Hettinger, R.D.

This is a point coverage that contains data for coal and otherstratigraphic horizons in the John Henry Member of the StraightCliffs Formation (Upper Cretaceous) east of 112 degrees oflongitude in the Kaiparowits Plateau. The item map# is the numberon the index map (Figure A, Plate 1) that refers to a record in adata table (Appendix 1) in Hettinger and others (1996). Bufferswere drawn at a three-mile distance from data points in thiscoverage to create the reliability coverage. This coverage alsoincludes arcs representing lines of cross section shown in Figs. B,C, D and E, Plate 1 (Hettinger and others, 1996).

This is a polygon coverage of the inclination of strata within theKaiparowits Plateau. Inclinations of strata are attributed incategories that range from 0 - 6, 6 - 12, 12 - 25, and > 25degrees. The range-of-dip was compiled at 1:125,000-scale fromstructure contour lines and from dip measurements on 1:24,000-scalepublished geologic maps of the Kaiparowits Plateau. These geologicmaps are referenced in figure 2 of Hettinger and others (1996).The outside polygon defines the base of the coal-bearing John HenryMember of the Straight Cliffs Formation (Upper Cretaceous) east of112 degrees of longitude. The northern boundary is delineated bythe Paunsaugunt fault and volcanic rocks of Tertiary age. The areawithin this polygon...

This is a polygon coverage of the outcrop of the base of the DripTank Member of the Straight Cliffs Fm. (Upper Cretaceous) east of112 degrees of longitude. The northern boundary is delineated bythe Paunsaugunt fault and volcanic rocks of Tertiary age.

This is a polygon coverage containing eleven different attributes of information including net coal thickness and estimated coal tonnages in the Calico and A-sequences in the Kaiparowits Plateau study area. This layer was derived from a "union" process, i.e., intersection and overlay of numerous layers and retaining attributes of each. It is the result of computing the geometric intersection of ten polygon coverages using the Environmental Systems Research Institute, Inc. (ESRI) Arc/Info UNION command, and finally calculating coal tonnage in INFO. Net coal thickness values are from 209 data points and represent all coal beds that are more than 1 foot thick.CARE SHOULD BE TAKEN IN USING THE COAL THICKNESS AND COAL...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
