SUMMARY:AGS Monthly Meeting
DESCRIPTION:Atlanta Geological Society Monthly Meeting. \nSpeaker: Bill Witherspoon \nTopic: Along the Divide – What Shapes Our Mountains? \nAbstract: Trivia question — What connects Okefenokee Swamp\, the Georgia State Capitol\, the trailhead at North Carolina’s Whiteside Mountain\, and Terra Incognita Vineyard near Clarkesville?  Answer — the Eastern Continental Divide (ECD). \nI created “Along the Divide” for a “talk & walk” this month at Terra Incognita Vineyard. The program traces the ECD from the sandhills of Florida through Atlanta to the peaks of North Carolina. In northeast Georgia\, the focus is on the stream capture event that led to Tallulah Gorge and a signature bend in the GA-SC boundary. At Whiteside\, the program considers a travel writer’s claim that this is “the world’s oldest mountain” and argues that the opposite is closer to the truth. This leads into the recent excitement over possible Neogene uplift in the Southern Appalachians as well as pushback in a 2022 review article by Virginia Tech researchers.

SUMMARY:Field trip to Arabia Mountain
DESCRIPTION:Following is taken from abstract by Dr. Aislin N. Reynolds\, Georgia Tech \nThe formation of surface parallel exfoliation fractures in rock domes produces some of the most celebrated and curious landforms on Earth. More than a century of observations\, including direct measurement of active exfoliation events\, highlight the key roles of solar heating and subcritical fracture propagation in rock exfoliation. Here we present new insights from Arabia Mountain\, a biotite orthogneiss dome near Atlanta\, Georgia (USA) that experienced a spontaneous exfoliation event of a formerly quarried surface in July 2023. The event uplifted a ~250 m2 area over 30 cm\, as revealed by digital elevation model differencing and field measurements. Following the event\, instrumentation was installed to monitor continued fracturing during summer 2024\, including surface parallel stresses\, local seismic waves\, and surface air and rock temperatures. Multiple additional exfoliation events were witnessed in-person during equipment installation\, including direct observation of progressive fracture propagation and explosion. \nParticipants will meet at the Davidson-Arabia Mountain Nature Center at 8:30 AM on Sunday\, August 4th\, 2024. The hike will start at 9:00 and last until approximately 11:30 AM. Please bring water and sun protection. \nParticipants must complete a waiver: https://atlantageologicalsociety.org/participation-waiver/

SUMMARY:Special Online Presentation--Thermally Induced Fracturing: New Insights from Active Exfoliation at Arabia Mountain\, Georgia
DESCRIPTION:This presentation provides geologic background prior to a field trip to the Arabia Mountain on August 4\, 2024 \nThe speaker will be Dr. Aislin N. Reynolds\, President’s Postdoctoral Fellow at Georgia Tech \nAbstract: The formation of surface parallel exfoliation fractures in rock domes produces some of the most celebrated and curious landforms on Earth. In 1904\, G.K. Gilbert outlined three mechanisms to produce exfoliation fractures: (1) original cooling of the rock\, (2) decompression during rock exhumation\, or (3) post-exhumation surface processes. More than a century of observations\, including direct measurement of active exfoliation events\, highlight the key roles of solar heating and subcritical fracture propagation in rock exfoliation. Here we present new insights from Arabia Mountain\, a biotite orthogneiss dome near Atlanta\, Georgia (USA) that experienced a spontaneous exfoliation event of a formerly quarried surface in July 2023. The event uplifted a ~250 m2 area over 30 cm\, as revealed by digital elevation model differencing and field measurements. Following the event\, instrumentation was installed to monitor continued fracturing during summer 2024\, including surface parallel stresses\, local seismic waves\, and surface air and rock temperatures. Multiple additional exfoliation events were witnessed in-person during equipment installation\, including direct observation of progressive fracture propagation and explosion. Observations and stress and seismic measurements all suggest a strong correlation with diurnal thermal cycles as captured by thermal sensors. These observations are compared with predicted stress distribution models informed by bulk-property measurements and regional geologic conditions to investigate the broader question: is the formation of exfoliation joints more sensitive to surface processes (e.g. solar heating and weathering)\, confining stresses related to topography and erosion\, or interactions of regional (i.e. tectonic) stresses with topography? Understanding the mechanisms driving exfoliation fracturing in rock domes will better constrain the sensitivities of these domes to future climate evolution\, with implications for forecasting rockfall hazards.

SUMMARY:PG Workshop: Petrology and Petrography
DESCRIPTION:Topic: Professional Geologist Candidate Workshop: Petrology and Petrography\n\nInstructor: Steven Stokowski\n\nWhen: 10am-12noon\, July 27\, 2024\n\nWhere: Zoom presentation. To sign up\, please click here\n\nCourse Syllabus: This review will cover petrography and petrology relevant to minerals and rocks. Emphasis will be on facts and calculations that are likely to be presented in the ASBOG Exam. The petrography review will focus upon the microscope tools and microscope methods used by geologists to perform their duties. The primary focus will be on reflected light (RL) and polarized light microscopes (PLM)\, ubiquitous in classic geology departments\, but often optional in departments that emphasize groundwater and environmental geology. The petrology review will cover the classification and origin of igneous\, metamorphic\, and sedimentary rocks\, including coal. I will discuss field and laboratory classifications based upon color\, grain size\, and mineral content.\n

SUMMARY:AGS Annual BBQ Social
DESCRIPTION:It’s time to start planning for the annual BBQ social. Remember last year’s event with lots of door prizes and Tony and his jokes? Who can top that?  Well\, we can try but we need volunteers\, and sponsors to make it happen. We only have three more monthly meetings before the Social. So\, in the next few weeks\, can you or your company provide a $100-$200 donation to help sponsor this annual event?  Or maybe you can volunteer and join me to set up/clean up the dining area\, check in guests\, take dues\, help with door prizes or you could be the Master of Ceremonies. Think about it and let me know as soon as you can. \nIf you have never been to the June BBQ Social it will be in the rotunda with the dinosaurs. Reservations are not needed but I will try to get a head count so I can buy enough food to have leftovers. The dinner menu includes barbecue chicken and pork\, bread\, mac and cheese\, BBQ beans\, sweet and unsweet tea\, and cobbler and cookies for dessert. While we eat\, Pamela will give her presidential address followed by door prize giveaways. The Big Screen Movie starts after dinner. Sponsors are welcome to set up a meet and greet table or give a short presentation. \nPlease let me know if you can help out\, bring company SWAG\, geology books\, maps\, rocks\, fossils donations for door prizes. Thanks again John Salvino Hospitality Chair and Treasurer johnsalvino@bellsouth.net \nAnnual BBQ Social: Tuesday\, 6pm\, June 25\, 2024 - *Members Free\, Guests $5\n*Membership must be current for 2024.

SUMMARY:January 27 Professional Geologist Candidate Workshop: Geophysics
DESCRIPTION:When: 10am-12noon\, January 27\, 2024\nWhere: Zoom presentation.  Contact Benjamin Black for login details: benjamin.black@geologicllc.net \nCourse Syllabus: Geophysical techniques are often cost-effective and safe ways to investigate the subsurface. Using these tools\, engineers and geologists can characterize sites and image subsurface conditions better.  Common applications include determining lithology\, depth to rock\, integrity and quality of rock masses\, fracture and foliation orientation\, locating subsurface hazards such as voids or manmade objects (utilities\, storage tanks\, waste\, burials etc.)\, and prospecting for natural resources.   Geophysical methods can be deployed from the land surface\, from the air\, on bodies of water\, and in borings. \nSome of the most common methods used are electrical resistivity imaging\, electromagnetic methods\, seismic methods (seismic refraction\, seismic reflection\, and surface waves)\, ground penetrating radar\, magnetic methods\, gravity methods\, and geophysical borehole logging. Geophysical methods work very well in tandem with a boring program for imaging the subsurface between boreholes. Also\, boring data is often critical for calibrating geophysical data to develop accurate subsurface models using geophysics.  In this presentation\, I will explain how each method work and the output\, and discuss applications and limitations. \n​Course Instructor: Jorgen Bergstrom is a licensed geophysicist and geologist and an expert in the field of near-surface geophysics.  He has over 25 years of experience with geophysical methods and instruments in the United States and Europe. During his career\, he has conducted numerous geophysical investigations\, assisting clients with characterizing the subsurface using geophysical methods\, and has authored numerous published papers discussing various geophysical technologies.

SUMMARY:AGS Monthly Meeting
DESCRIPTION:Speaker Ajoy Baksi \nTopic: The timing and duration of flood basalt traps\, India and the Columbia River Basalt Group\, USA. \nSpeaker bio: Ajoy Baksi obtained a M.S. (1967) and Ph.D. (1970)\, from the University of Toronto (Canada) in (Geo)Physics\, following degrees in Physics and Exploration Geophysics in India. Worked in Canada\, India and Australia\, before moving to Louisiana State University in 1982. Research was focused on geochronology (argon dating methods) and geochemistry; retired in 2008 and moved to Atlanta in 2019. In “Emeritus state” have continued to publish occasionally. Most recently three papers in 2022\, on the Deccan and Rajmahal Traps (India)\, Columbia River Basalts (USA). \nAbstract: Interest in flood basalt volcanism (encompassing > 200\,000 km3 of rocks) has increased over the past 60 years\, including the possible effect on the environment\, of their eruption. This effort looks at the latest research on geochronological aspects of their timing and duration of formation. Until the last decade\, the argon dating methods were the the only tools used for this purpose. Initial K-Ar work in the 1970s\, on whole-rock basalts\, showed that bulk of the Columbia River Basalt (CRB) was formed in < 2 m.y. at ~16 Ma. The next two decades produced scattered results for the Deccan and Rajmahal Traps (India)\, the CRB (USA)\, the Siberian Traps (Russia)\, the Parana (South America) and Karoo and Etendeka (South Africa). Following improvements on technical fronts\, 40Ar/39Ar dating of both whole-rock samples and plagioclase separates\, showed that the bulk of the Siberian Traps and Parana were (each) formed in ~ 1 m.y. around 250 Ma and 135 Ma\, respectively. This effort summaries work on the Deccan and the CRB over the past decade. The latest 40Ar/39Ar results show that each of these was formed in ~ 700 ka around 66 Ma and 16.4 Ma\, respectively. The advent of U-Pb dating on single zircons\, taken from layers intercalated with the flows in these provinces\, has reinforced these conclusions. The obstacles facing such efforts are examined\, as well as the lacunae of the 40Ar/39Ar and U-Pb dating methods. These techniques produce ages with precision < ±0.5 m.y. over the Phanerozoic; their accuracy must be carefully judged on both geological and physical/mathematical grounds. \n

SUMMARY:PG Exam Workshop: Petrology and Petrography
DESCRIPTION:Zoom presentation. Contact Ben Black at benjamin.black@geologicllc.net for login information (AGS membership required) \nCourse Syllabus: This review will cover petrography and petrology relevant to minerals and rocks. Emphasize will be on facts and calculations that are likely to be presented in the ASBOG Exam. The petrography review will focus upon the microscope tools and microscope methods used by geologists to perform their duties. The primary focus will be on reflected light (RL) and polarized light microscopes (PLM)\, ubiquitous in classic geology departments\, but often optional in departments that emphasize groundwater and environmental geology. The petrology review will cover the classification and origin of igneous\, metamorphic\, and sedimentary rocks\, including coal. I will discuss field and laboratory classifications based upon color\, grain size\, and mineral content.\nAfter discussing the tools and methods of petrography\, we will review mineralogy and then mineral identification with a microscope. The major chemical and crystal classes of minerals will be covered\, followed by their diagnostic features and associations. Then\, the characteristic features of minerals in thin section will be presented. This will include crystal shapes\, pleochroism\, birefringence\, twinning\, and associated and alteration minerals. The IUGS classification schemes for plutonic and volcanic rocks will be described including QAPF diagrams. Bowen’s reaction series will be covered as will phase equilibria. For metamorphic rocks\, the fabric\, composition\, and mineral facies schemes and their applications will be presented. Sediments and sedimentary rocks will be subdivided into quartz and silicate-rich sediments and rocks\, carbonate sediments and rocks (limestones and dolomites)\, carbonaceous sediments and rocks (peat\, lignite\, bituminous coal\, etc.)\, and other\, less-common\, rock types. The identification of heavy minerals will be presented\, as will grain size\, roundness\, and texture analysis analyses of sediment grains. The relationship of Goldich’s dissolution series and Bowen’s series will be explained\, and how Goldich’s observations explain the chemical and mineral composition of sedimentary rocks\, especially arenites through lutites. For carbonate rocks\, the highlights of the distinctions between limestones and dolomites will be covered\, as will carbonate rock classification schemes\, especially Folk’s particle type and texture classification. For carbonaceous sediments\, we will discuss the characteristics of peat through anthracite. \nInstructor: Steven Stokowski\, CPG\, is the owner and materials geologist of Stone Products Consultants. Steve’s primary professional interests are aggregates and concrete petrography. Steve has extensive geological and petrographic experience across the US.
