A seismic reflection study over the Bane anticline in Giles County, Virginia
A seismic reflection study over the Bane anticline in southwest Virginia (37° 16' 50" N, 80° 41' 30" W) was made in an attempt to gain information about the thickness of sedimentary rocks in this part of the Appalachian Valley and Ridge province. Eleven seismograms were obtained. In addition to …

Structural Evolution of the Beaver Lodge Portion of the Nesson Anticline, North Dakota
<p>The structural development in the area of Beaver Lodge Field, Williams County, North Dakota, has been determined from Cambrian (Deadwood) through Late Cretaceous (Greenhorn) time. Detailed structural data defines two areas of structural closure occurring along a basement structural trend. One of …

Geochemical characteristics and microbial diversity of CO2-rich mound springs of the Tierra Amarilla anticline, New Mexico
… of the Nacimiento fault at the Tierra Amarilla anticline (TA). Geochemical data on the spring waters show 3He/4He ratio of 0.17-0.20 RA which indicates the presence of mantle-derived helium in the groundwater. Carbon isotope values range from -4.6 to -8.1 per mil, suggesting that some of the CO2 …

Conodont Biostratigraphy of the Middle and Upper Ordovician Viola Group of the South-Central Oklahoma Arbuckle Anticline
… Group of the south-central Oklahoma Arbuckle Anticline is described. Over 8000 identifiable conodont elements were recovered from 115 samples collected from the Viola Group at a single locality . The stratigraphic ranges of the conodonts are used to graphically correlate the Viola Group of the …

Beekmantown Formation-Middle Ordovician limestone unconformity on the northwest limb of the Green Ridge anticline near Fincastle, Virginia
The depositional and erosional history can be summarized as follows: 1) Subtidal carbonate shelf sedimentation through Early Ordovician (and including early Middle Ordovician White Rock?) time represented by the Beekmantown Formation. 2) Emergence of a Beekmantown terrain due to eustatic lowering …
