Along each side of the dusty Cerro Gordo road, you examine a thick succession of black shales and black limestones of Pennsylvanian and Permian age assigned to the Keeler Canyon Formation. Individual limestone beds are meters thick, and each one grades from coarse ( millimeters) abraded and broken fossil particles at the bottom to mud. Permian rocks of Wolfcamp, Leonard, and Guadalupe age of the Northwest shelf are found in the northwestern part of the report area; rocks of Ochoa age are not preserved. The basal Permian formation of the shelf, the Hueco Limestone, is not exposed at the surface, and the lower part of the overlying Yeso Formation is also buried.
The Moenkopi Formation is a geological formation that is spread across the U.S. states of New Mexico, northern Arizona, Nevada, southeastern California, eastern Utah and western unit is considered to be a group in Arizona. Part of the Colorado Plateau and Basin and Range, this red sandstone was laid down in the Lower Triassic and possibly part of the Middle Triassic, around The Grand Forks-Eholt map area is underlain predominantly by a sequence of moderately deformed and slightly metamorphosed sedimentary and volcanic rocks, previously termed the "Anarchist Group" and ranging in age from Permian/or Earlier to Middle Jurassic. These rocks are divisible into two distinct sequences: (a) cherts (Knob Hill), quartzites, phyllites, and greenstones of Permian/or Earlier.
Shales are the most common radioactive lithology that is seen on a gamma-ray log. However, other lithogies can generate high gamma-ray readings and their expected API values can be computed by applying the multipliers to analyses of thorium (ppm), uranium (ppm), and potassium (%), where these are available.

The Permian Basin is one of the oldest and most widely recognized oil and gas producing regions in the U.S. The Permian Basin covers approximat square miles and encompasses 52 counties in New Mexico and Texas. Here are some links to the data we have available on the Permian Basin, Wolfcamp, Bone Springs, Spraberry.
The Permian, named after exposures in the southern Urals of Russia, which was within the ancient kingdom of Permia, has three named series/epochs—Cisuralian (type area is the southern Urals), Guadalupian (type area is the Guadalupe Mountain region of West Texas), and Lopingian (type area is South China) (Fig.
).The ratified or candidate Global Boundary Stratotype Sections and Points. The Permian Basin is a complex sedimentary system located in the foreland of the Marathon–Ouachita orogenic belt.
It covers an area of more t square miles and extends across 52 counties in West Texas and Southeast New Mexico. The Permian Basin was developed in the open marine areaFile Size: 2MB. I. Introduction. Between the River Severn and the village of Enville in South-east Shropshire, and again round the southern half of the South Staffordshire Coalfield, there are certain bands of rocks cemented and hardened by calcareous matter—namely, calcareous conglomerates, cornstones, and calcareous sandstones—which constitute parts of the group classified by the officers Cited by: 9.
Widespread mid-Tertiary vulcanism spread a blanket of flow and pyroclastic rock over Trans-Pecos Texas. In the Eagle Mountains rhyolitic and trachytic flow rock, volcanic breccia, and flow breccia overlie centroclinally dipping Cretaceous strata.
The high, interior part of the Eagles is a crescent-shaped stock composed of the Eagle Peak Syenite. Permian Period - Permian Period - Occurrence and distribution of Permian deposits: Permian rocks are common to all present-day continents; however, some have been moved—sometimes thousands of kilometres—from their original site of deposition by tectonic transport during the Mesozoic and Cenozoic eras.
For example, Permian glacial terrestrial and marine deposits typical of the cold high. The Sadlerochit Group extends Statistical analysis of a basal permian conglomerate from the Eagle Area across the North Slope of Alaska, from outcrops in the Arctic National Wildlife Refuge (ANWR) (Determan, ; Crowder, ), westward into the subsurface, reaching a depth of approximately ft ( m) at Prudhoe Bay Field, and on to the Chukchi Sea coast (Figure 1).In the Prudhoe Bay area of the central North Slope, the Sadlerochit Group.
The Permian basin of west Texas and Southeastern New Mexico is one of the major petroleum producing regions of the United States. This basin produced 3% of the world's petroleum in and in that year, 1% of the world's proven reserves were in the Permian basin (Robichaud, ).
Most of the Upper Permian hydrocarbon reservoirs are in San Andres and Grayburg formations (Galloway et al. Book and Open-File Report Sales U.S. Geological Survey Federal Center, Box Denver, CO Library of Congress Cataloging-in-Publication Data Johnson, Samuel Y.

At Sop Pong and Bun Tai, plant compressions were described by Vozenin-Serra (), confirming the occurrence of the Cathaysian genus Gigantopteris in the Permian of Laos.

Permian Basin, also called West Texas Basin, large sedimentary basin in western Texas and southeastern New Mexico, U.S., noted for its rich petroleum, natural gas, and potassium deposits.

Scale: 1. Basal conglomerate definition, a conglomerate deposited on an erosion surface and constituting the bottom layer of a stratigraphic series. See more. Pennsylvanian–Permian strata within the Eagle Basin were sampled along a generally east–west transect consisting of four detailed measured sections across the basin (Figs.
2 and 5, panels 1–4). These strata span Early Pennsylvanian through Late Pennsylvanian time. Further analysis of petrophysical log curve data incorporated into area Cross Sections clearly highlights potential pay zones.
