Magnetic Characteristics of Carboniferous Continental Depositional Systems: Implications for the Recognition of Depositional Hiatuses
Quaternary magnetic studies have provided the conceptual framework to bridge magnetic studies into ancient systems. In cases where environmental materials have been subjected to diagenetic alteration two questions come to mind: 1) What part of the magnetic signal is preserved in the rocks; and 2) can the preserved signal be used to infer/identify magnetic patterns that are characteristic of the...
متن کاملMegafloral Perturbation across the Enna Marine Zone in the Upper Silesian Basin Attests to Late Mississippian (serpukhovian) Deglaciation and Climate Change
A significant vegetational change occurs in the Late Mississippian (Serpukhovian, Namurian A) across the Enna Marine Zone (EMZ), Upper Silesian Basin, Czech Republic. All plant clades were impacted, including both spore-producing and seed-producing taxa; wetland taxa were unaffected. Similar vegetational responses are not identified elsewhere although, basinwide, thick marine zones (e.g., Barbo...
متن کاملThe magnetic polarity stratigraphy of the Mauch Chunk Formation, Pennsylvania.
Three sections of Chesterian Mauch Chunk Formation in Pennsylvania have been studied paleomagnetically to determine a Late Mississippian magnetic polarity stratigraphy. The upper section at Lavelle includes a conglomerate with abundant red siltstone rip-up clasts that yielded a positive conglomerate test. All samples were subjected to progressive thermal demagnetization to temperatures as high ...
متن کاملOrigin of Discontinuities in Coal-bearing Strata at Roaring Creek (basal Pennsylvanian of Indiana)
Nelson, W.J., Eggert, D.L., DiMichele, W.A. and Stecyk, A.C., 1985. Origin of discontinuities in coal-bearing strata at Roaring Creek (basal Pennsylvanian of Indiana). Int. J. Coal Geol, 4: 355—370. Basal Pennsylvanian coal-bearing strata exposed along Roaring Creek, west-central Indiana, exhibit extreme lateral discontinuity. Coal seams abruptly change in thickness and elevation; they split, g...
متن کاملEchinoderm microtubule-associated protein -like protein 5 in anterior temporal neocortex of patients with intractable epilepsy
Objective(s):EMAP-like Protein 5 (EML5) is a new echinoderm microtubule-associated protein that is expressed in the central nervous system. The aim of this study was to investigate the expression profile of EML5 in the anterior temporal neocortex of patients presenting with intractable epilepsy (IE). Materials and Methods:Western blot assays were performed to determine EML5 expression in 36 su...
