Spatio‐Temporal Transitions in Paleozoic Bivalvia: A Field Comparison of Upper Ordovician and Upper Paleozoic Bivalve‐Dominated Fossil Assemblages

Historical Biology, 1989
Because of the uncertain relationship between relative abundance and taxonomic richness, abundance data are potentially critical components in any analysis of faunal dominance within fossil assemblages. However, such data are often not available in the literature. In this paper, relative abundance data collected during field work at 25 Upper Ordovician

Upper Paleozoic Petroleum System, Ordos Basin, China

Marine and Petroleum Geology, 2005
Abstract The Ordos Basin is a typical lapped basin, including three sequences of strata: early Paleozoic, late Paleozoic and Mesozoic, with a total thickness of 4000–6000 m. Impermeable sealing beds are well developed at the top and base of the upper Paleozoic sequence, separating it from the Mesozoic and the lower Paleozoic strata to form an ...

UPPER PALEOZOIC CLIMATIC REGIONS IN NORTHWESTERN EURASIA

International Geology Review, 1962
It is necessary to consider paleo-environments in geochemical analysis of sediments. In a study of the upper Paleozoic humid-climate sediments of the U.S.S.R. the indicators of the geochemistry of a given environment included 1) distribution of chemical elements in the series sandstone-siltstone- clay-marl-limestone, 2) iron balance, 3) chemistry of ...

Upper Paleozoic Paleogeography of Idaho: ABSTRACT

AAPG Bulletin, 1980
In south-central Idaho, Mississippian rocks were deposited in flysch-trough and carbonate-bank environments. Lower Mississippian detritus shed from the Antler highland accumulated to a thickness of more than 3,000 m in an adjacent elongate flysch-trough and End_Page 785------------------------------ spread eastward to the inner craton margin.
