Bracciated Greenfield Dolomite containing porphyroclasts of dolomite and sphalerite. The sample comes from a graben in the central uplift (from page 396 of The Serpent Mound Cryptoexplosion Structure, Southwestern, Ohio by Stephen P. Reidel and Frank L. Koucky part of the Geological Society of America's GSA Cincinnati '81 Field Trip Guidebooks, v. 2. Economic Geology, Structure). The Serpent Mound Impact Structure is an approximately 9-mile-diameter area of highly disturbed and structurally deformed bedrock at the intersection of Adams, Highland and Pike counties. The area of the impact structure has dolomite, shale, limestone, sandstone, and siltstone lithologies. Because of the geologic forces that have acted...
A specimen showing spheralite replacment without visible fracturing. The specimen shows contemporaneous solution of the dolomite and deposition of sphalerite. The photograph was taken by Stephen P. Reidel for his Geology of the Serpent Mound Cryptoexplosion Structure a thesis submitted in partial fulfillment of the degree of Master of Science to the University of Cincinnati in 1972. It appears as Photo 40 in his thesis document. The specimen was collected from the central uplift area of the Serpent Mound Impact Structure near the fifth and southernmost of Reidel's seven radiating anticlines (see Location 5 on the index map for Plate 1 in Appendix IV of the thesis). The Serpent Mound Impact Structure is an approximately...
A specimen that shows spheralite filling fractures and replacing the dolomite. Bleaching of the dolomite, where replacment occurred is not common but occassionally it is found near the dark
A specimen with sphalerite in a calcite vein. The photograph was taken by Stephen P. Reidel as part of the research for his Geology of the Serpent Mound Cryptoexplosion Structure a thesis submitted in partial fulfillment of the degree of Master of Science to the University of Cincinnati in 1972. The location given is approximate to the central point of the structure based on the specimen being collected by Dr. Reidel at the Serpent Mound Impact Structure, but the exact location in the structure not available at this time. The Serpent Mound Impact Structure is an approximately 9-mile-diameter area of highly disturbed and structurally deformed bedrock at the intersection of Adams, Highland and Pike counties. The area...
Sphalerite filling fractures and cementing breccia fragments in Greenfield-Tymochtee Dolomite from along a boundary fault on the southeastern side of the impact structure near Ohio State Route 41 (from pages 395 and 402 for the description of Stop 6 in The Serpent Mound Cryptoexplosion Structure, Southwestern, Ohio by Stephen P. Reidel and Frank L. Koucky part of the Geological Society of America's GSA Cincinnati '81 Field Trip Guidebooks, v. 2. Economic Geology, Structure). The Serpent Mound Impact Structure is an approximately 9-mile-diameter area of highly disturbed and structurally deformed bedrock at the intersection of Adams, Highland and Pike counties. The area of the impact structure has dolomite, shale,...
A specimen of fractured Peebles-Greenfield Dolomite from outside the central uplift of the Serpent Mound Impact Structure with spheralite cementing breccia in the fracture zone. The photograph was taken by Stephen P. Reidel for his Geology of the Serpent Mound Cryptoexplosion Structure a thesis submitted in partial fulfillment of the degree of Master of Science to the University of Cincinnati in 1972. The sample is pictured as Photo 35 in the thesis document. The Serpent Mound Impact Structure is an approximately 9-mile-diameter area of highly disturbed and structurally deformed bedrock at the intersection of Adams, Highland and Pike counties. The area of the impact structure has dolomite, shale, limestone, sandstone,...
A specimen of fractured Peebles-Greenfield Dolomite from outside the central uplift of the Serpent Mound Impact Structure with spheralite cementing breccia in the fracture zone. The photograph was taken by Stephen P. Reidel for his Geology of the Serpent Mound Cryptoexplosion Structure a thesis submitted in partial fulfillment of the degree of Master of Science to the University of Cincinnati in 1972. The specimen is from the same location as the specimen pictured as Photo 35 in the thesis document. The Serpent Mound Impact Structure is an approximately 9-mile-diameter area of highly disturbed and structurally deformed bedrock at the intersection of Adams, Highland and Pike counties. The area of the impact structure...
A thin section showing breccia and shattered prophyroclasts of sphalerite from the Serpent Mound Impact Structure. The area of the impact structure has dolomite, shale, limestone, sandstone, and siltstone lithologies. Because of the geologic forces that have acted on the site of the impact crater, bedrock in the area is a mixture of uplifted, down dropped, faulted, folded and eroded rock from the Ordovician, Silurian, Devonian and Mississippian Geologic Periods. The photograph was taken by Stephen P. Reidel for his Geology of the Serpent Mound Cryptoexplosion Structure a thesis submitted in partial fulfillment of the degree of Master of Science to the University of Cincinnati in 1972. The Serpent Mound Impact Structure...
