Proterozoic and Paleozoic evolution of the Blue Ridge geologic province in northern Virginia

Bill Burton, Steve Schindler and Alan Pitts, USGS

Saturday, May 14 at 9 AM, starting in Haymarket, VA

A one-day trip across the northern Virginia Blue Ridge geologic province highlighting published geologic mapping and geochronology of Mesoproterozoic rocks that constitute the core of the Blue Ridge anticlinorium and Neoproterozoic cover-sequence rocks on the fold limbs.

 Directions to meeting place from I-66 W:  Take I-66 W in the direction of Front Royal.  Take exit number 40 to US-RT 15 N.  Turn right onto Heathcote Blvd.  Take the next right into the Heathcote Blvd Park and Ride.  This is a VDOT commuter parking lot where we can leave cars safely for the day. There are no restroom facilities or food services at this location. For restrooms or snacks, plan to stop before arriving at the meeting point–for example, at the Sheetz Gas station on the south side of I-66 just 5 mins from this location, which is part of a larger shopping center with a Subway, Aldie Grocery Store, and others.  Arrive early if you need to use these services.  Introductory remarks in the parking lot will start at 9 AM.  We will need to consolidate cars before leaving—please carpool to the meeting place if you can.

It will feature a full slate of three talks. Join us to learn what super deep diamonds can tell us about the causes of deep focus Earthquakes, about volcanic climate warming, and about the initial analysis of the asteroid Ryugu. If you come to the Cosmos Club, please remember to bring your Covid vaccination card. It will be checked. And don’t forget to save some room for the beer. Non-members are welcome! Details of the talks, including the Zoom link, have been sent to members. Contact Michael Ackerson (ackersonm[at]si.edu) for the Zoom link if you do not have it.

and feature a full slate of three talks. Join us to learn what paleomagnetic tools can tell us about the early Solar System, what zircon can tell us about environments on the early Earth, and using infrasound to characterize large volcanic eruptions. Zoom will open at 7:30 PM for you to socialize, and the meeting will begin at 8:00 PM. Talks will be 20 minutes with questions to follow.
