UPPER DEVONIAN ACRITARCHS AND MIOSPORES FROM THE GEIRUD FORMATION IN CENTRAL ALBORZ RANGE, NORTHERN IRAN
The Geirud Formation consists mainly of clastic sediments which are interbedded with limestone stringers. This rock unit is well-exposed along the Central Alborz Range in northern Iran. The Geirud Formation rests unconformably on the Mila Formation (Upper Cambrian) and is conformably overlain by the Mobarak Formation (Lower Carboniferous). This study was undertaken to determine the geologi...
متن کاملJoint sets that enhance production from Middle and Upper Devonian gas shales of the Appalachian Basin
Terry Engelder, a leading authority on the recent Marcellus gas shale play, received his B.S. degree from Pennsylvania State University (1968), his M.S. degree from Yale University (1972), and his Ph.D. from Texas A&M University (1973). He is currently a professor of geosciences at Penn State and has previously served on the staff of the U.S. Geological Survey, Texaco, and LamontDoherty Earth O...
متن کاملRED COLOURING OF THE UPPER RED FORMATION IN CENTRAL PART OF ITS BASIN, CENTRAL ZONE, IRAN
This study attempts to investigate the origin of red pigments, time of reddening, and processes responsible for red colouring of the Upper Miocene age Upper Red Formation, the most important clastic unit in central Iran. Mineralogical composition and textural properties of the studied sequences show that the Upper Red Formation sequences were not red when deposited, although some parts of red p...
متن کاملSequence Stratigraphy of Upper Mississippian Strata in the Central Appalachians: A Record of Glacioeustasy and Tectonoeustasy in a Foreland Basin Setting
The Upper Mississippian Hinton, Princeton, and Bluestone formations of southern West Virginia constitute a westwardly thinning wedge of strata that filled the central Appalachian basin over a ~7 million year time interval. Up to 17 unconformity bounded, transgressiveregressive sequences comprise the study interval in the basin depocenter. Five sequence types are recognized based upon the degree...
