Diagenetic history
WebFeb 1, 2009 · Illite age analysis (IAA) is a classical method for extracting diagenetic and detrital ages from mixed ages measured by K-Ar. This approach is based on measuring the masses of diagenetic and detrital illitic components in a few different grain-size fractions of one rock sample and measuring the mixed ages of these fractions. The 1Md illitic … WebThis report presents preliminary results of a mineralogic and diagenetic study of some low-permeability sandstones from measured surface sections and cores obtained from drill holes in the Piceance Creek Basin of northwestern Colorado. A documentation of the mineralogy and diagenetic history will aid in the exploration for natural gas and in the development …

WebBone histology has proved to be a valuable tool to obtain information about the palaeobiology and early taphonomic history of fossil vertebrates. However, there are still many extinct taxa for which bone histology studies could be applied to deduce information about their life history and early diagenetic changes. WebVolumetrically, silica and carbonate cementation were the most important diagenetic processes. Chlorite is the dominant authigenic clay mineral. Porosity is predominantly secondary, and the dissolution of quartz and quartz overgrowths provided much of the reservoir in these highly productive strata. Authors: Haiduk, J P Publication Date:
WebThe diagenetic history and porosity evolution of these grainstones are very complicated. Both near-surface and burial diagenesis are obvious, based on both petrographical and geochemical studies. The submarine diagenesis is characterized by micritization and isopachous fibrous cementation. The subaerial diagenesis can be subdivided into ... WebDec 8, 2024 · The sandstone units of the Early Cretaceous Lower Goru Formation are significant reservoir for gas, oil, and condensates in the Lower Indus Basin of Pakistan. Even though these sandstones are significant reservoir rocks for hydrocarbon exploration, the diagenetic controls on the reservoir properties of the sandstones are poorly …
WebDec 9, 2024 · Together, these properties of primary and diagenetic carbonate minerals and shallow-water sedimentary systems lead to a characteristic relationship between bulk δ 44 Ca and Sr/Ca and provide a means with which to characterize the effects of mineralogy and early marine diagenesis on the geochemistry of shallow-water carbonate sediments … WebJun 1, 1995 · The petrography, stable isotopes, fluid inclusions, cathodoluminescence and mirror/trace element chemistry of these sandstones are used to establish the diagenetic history and controlling factors.
