Скачать или смотреть PART 2 of 3: Water bearing fracture in tectonically fractured carbonate

Part 2 - This video examines an interval from 213 ft - 218 ft below ground surface in Virginia State Observation Well 009 in Pulaski County as recorded by DEQ Groundwater Characterization staff on 3/25/08. The video shows intense fracturing of Elbrook or Rome Formation carbonate beds in the hanging wall of the Peak Creek fault system that are mostly recrystallized with calcite. A near-horizontal water bearing fracture with an oxidized halo cross cuts the deformed unit at 218'. The former supply well is located 37.0483672797222 / -80.6286453333333 NAD83 and is currently a state observation well used for drought monitoring. http://www.deq.virginia.gov/gwcharact...
