Meet 7:30 AM at Vulcan's Manassas Quarry. Out by 12 or when the quarry employees have to leave. The rock is diabase, with one level having a layer of hornfels. This quarry has produced prehnite, apophillite, calcite, amethyst, other quartz, chalcopyrite, pyrite, epidote, and zeolites -- stilbite, chabazite, heulandite, stellerite, and others. Our recent joint trip with the Northern Virginia club was quite productive, hence the second visit (I have invited them to join us on that day also).Please let me know if you plan to attend by May 4, so I can provide the quarry with an accurate headcount. Children 10 and up are welcome if accompanied and well supervised by a parents and use the required safety gear. Directions:From the Beltway, go West on 66.
Take Exit 44, SR-234. Go 3.6 Miles
Turn Left onto Wellington Lane. The quarry will be on your left, about .5 miles from Rt 234.
