The plays are distinguished by their trapping mechanism, reservoir type, and the age of their producing intervals. Fifteen conventional plays and two continuous-type unconventional plays are described. They are: Step 3: Consistency with Other Features. Compare your environmental hypothesis to the characteristics implied by other sedimentary structures in the column and evaluate whether they are consistent with your tentative environmental interpretation. Examples of other sedimentary structures: Trough cross stratification.

5.In other words, itcan also be defined as stratigraphic map indicating distribution of sedimentary facies within a specific geologic unit. 5. Paleo-geologic Maps: Paleo-geologic maps were introduced by Levorsen in 1933 A map that shows the areal (relating to area) geology of an ancient surfaceat some time in the geologic past, …

Stratigraphy is a part of geology concerned primarily with layering in sedimentary rocks (and to a limited extent in some volcanic rocks). Nicolas Steno (1638-1686) is generally credited with defining some of the principles of stratigraphy, specifically the law of superposition which, put simply states that in undisturbed strata the youngest ...

This map represents a compendium of the geological mapping as presented in the out-of-print bulletins published by the Hawaii Division of Hydrography from the 1935 to 1960. The rock unit nomenclature was later revised and updated to conform to the North American Stratigraphic Code (1983). Texas geologic map data.

Stratigraphic sections of all systems of the Paleozoic are present and reach a maximum thickness in excess of 25,000 ft; however, complete vertical sequences of Paleozoic strata are rare. The Permian Basin, one of the most prolific petroleum provinces of North America, is now in a mature stage of exploration and development.These geologic elements are documented and integrated into a series of maps. The Permian Basin maps consist of layers of geologic and production information that users can view either as separate thematic maps (such as Figure 1) or as interactive layers of the U.S. Energy Mapping System. Data sources include

Map 1 shows the trace of an unconformable contact between slate and an overlying conglomerate. Conformably overlying the conglomerate is sandstone and limestone. Lab 2, Map 1: Stratified units overlying slate with veins. a. The Stratigraphic Principle. Stratigraphy organizes bodies of rock chronologically and spatially in accordance with their contained characteristics. It puts indirectly connected rock units together in a relationship. Stratigraphy is the substructure for remodelling the Earth’s history. It also plays a part in solving general geological questions.These geologic elements are documented and integrated into a series of maps. The Permian Basin maps consist of layers of geologic and production information that users can view either as separate thematic maps (such as Figure 1) or as interactive layers of the U.S. Energy Mapping System. Data sources include Plotting a structural contour map. Mapping the structural contours across a stratigraphic unit reveals a three-dimensional picture of its subsurface distribution, deformation, structural relief, and stratigraphic displacement along faults. The structure here is a north-plunging, asymmetric anticline, its eastern limb the steepest.Ordovician Chronostratigraphic Chart.
