Description/Abstract:
SECTIONS OF THE PALEOZOIC ROCKS THAT ARE EXPOSED IN THE FOOTHILLS OF T HE SANGRE DE CRISTO MOUNTAINS SHOW MUCH VARIATION OF THE PENNSYLVANIAN AND PERMIAN STRATA AND PROVIDE INFORMATION THAT MAY BE OF VALUE IN TH E INTERPRETATION OF THE SUBSURFACE STRATIGRAPHY OF THE LAS VEGAS PLATE AU IN SAN MIGUEL AND MORA COUNTIES, N. MEX., WHERE A BURIED PENNSYLVAN IAN AND PERMIAN SEDIMENTARY BASIN IS INDICATED. THIS BASIN OFFERS POS SIBILITIES OF OIL AND GAS ACCUMULATION IN BOTH STRUCTURAL AND STRATIGR APHIC TRAPS WHICH HAVE NOT BEEN ADEQUATELY TESTED. THE ACCOMPANYING M APS AND DIAGRAMS SHOWING THE DISTRIBUTION AND VARIATION OF THESE STRAT A AND OF THE SUPERJACENT MESOZOIC ROCKS IN AN AREA OF ABOUT 1,500 SQUARE MILES, ARE PRESENTED IN AN EFFORT TO SUMMARIZE PERTINENT INFORM ATION ON THIS BASIN. THE AREA CONSIDERED IS A PORTION OF TWO MAJOR PH YSIOGRAPHIC PROVINCES; NAMELY, THE SOUTHERN ROCKY MOUNTAINS AND THE GR EAT PLAINS. THE EASTERN MARGIN OF THE SANGRE DE CRISTO MOUNTAINS, WHI CH IS A PORTION OF THE SOUTHERN ROCKY MOUNTAIN PROVINCE, IS A COMPRESS ED, FOLDED AND FAULTED BELT AND IS A PART OF A MAJOR ANTICLINORIUM. I T IS THUS A FEATURE THAT CONTRASTS SHARPLY WITH THE ADJACENT LAS VEGAS PLATEAU, ONE OF THE MINOR DIVISIONS OF THE GREAT PLAINS. STRATA IN T HAT AREA ARE GENTLY FOLDED AND LOCALLY FAULTED AT THE SURFACE. AVAILA BLE INFORMATION SUGGESTS THAT THE PENNSYLVANIAN AND PERMIAN ROCKS AT DEPTH MAY DEPART FROM THIS SIMPLE STRUCTURE ALONG THE MARGINS OF THE I NDICATED SEDIMENTARY BASIN.
