Maps showing aeromagnetic survey and interpretation of the Virgin Mountains Instant Study Area Clark County, Nevada Maps showing aeromagnetic survey and interpretation of the Virgin Mountains Instant Study Area Clark County, Nevada

Data for the aeromagnetic map (fig. 1) of the Virgin Mountains Instant Study Area wre collected in 1978 and compiled at a scale of 1:62,500. North-south traverses were spaced at 0.8-km intervals at an altitude of about 300m above the surface of the ground. The contour interval is 20 and 100 gammas, depending on the steepness of local magnetic gradients in the Earth's magnetic field. A...

Maps showing coal resources of the Crumpler quadrangle, Mercer, McDowell, and Wyoming Counties, West Virginia Maps showing coal resources of the Crumpler quadrangle, Mercer, McDowell, and Wyoming Counties, West Virginia

Coal Geology The Crumpler quadrangle lies in the Appalachian Plateaus province, with the coal bearing Pocahontas and New River Formations of Pennsylvanian age having a gentle dip toward the northwest. Coal bed maps were prepared (figures 1-7) and resources were estimated (table 1) for seven of the many coal beds in the Crumpler quadrangle (Stricker, 1980, lists the names of the various...
