Abstract:
The Cenomanian succession in Rutbah City, western Iraq, is composed of siliciclastic carbonate with multicolored paleosoil layers that refer to unconformity surfaces within the Ms'ad Formation. The current study will examine the clay mineralogy and facies to determine the source of these clay minerals and depositional settings. Fifteen carbonate facies have been identified as three distinct facies associations (FA1–FA3). These FAs are supratidal to intertidal (FA1), semi-restricted lagoon (FA2), and shallow open subtidal ramp with patches of a rudist-bivalve reef (FA3). The reported Multispiri

AbstractThe K/Ar characteristics of 53 clay assemblages (Triassic–Cretaceous), representing the detrital, volcanogenic and arid-facies clay mineral associations, are interpreted in relation to their mineralogy, chronostratic age and geological origins. The K-bearing mineral components of the 1–2 μm, 0.2–1 μm and <0.2 μm fractions of each clay assemblage together display one of two characteristic patterns of K2O and 40Ar values (the K/Ar signature of the assemblage) on a 40Ar/K2O correlation diagram. Interpretation of the K/Ar signatures indicates that: (1) all of these clay assemblages are

Abstract:
AbstractClay minerals from Middle Jurassic lagoonal mudrocks, siltstones and silty fine-grained sandstones of the upper Great Estuarine Group (Bathonian) are divided into four assemblages. Assemblage 1, the most common assemblage, is rich in mixed-layer illite–smectite with attendant illite and kaolinite. Assemblage 2 is dominated by smectitic clay. These assemblages are indicative of primary Jurassic deposition. Illite and kaolinite were probably derived from the weathering of older rocks and soils in the basin hinterland and were deposited in the lagoons as river-borne detritus. The majority

AbstractThe evaluation of clays as barriers to fluid movement can be improved by geochemical methods that provide ways to examine the reactivity and weathering of minerals in soils and sediments.

AbstractLower Palaeozoic rocks crop out extensively in Wales, the Lake District of northern England and the Southern Uplands of Scotland; they also form the subcrop concealed beneath the English Midlands and East Anglia. These mainly marine sedimentary rocks were deposited in basins created during plate tectonic assembly of the various terranes that amalgamated to form the British Isles, 400-600 Ma ago. Final amalgamation occurred during the late Lower Devonian Acadian Orogeny when the basins were uplifted and deformed, producing belts of cleaved, low-grade metasediments, so-called slate belts

Clays deposited in marine evaporite sequences are strongly altered, and the most important factor determining their transformation is brine concentration. An X-ray diffraction study of clay minerals associated with the Lower and Middle Miocene evaporite formations of the Ukrainian Carpathian Foredeep indicated that the clay mineral assemblages in the gypsum facies are composed of smectite and illite, and, in some samples, mixed-layer chlorite–smectite and illite–smectite, as well as chlorite. In the halite facies, illite, chlorite, and mixed-layer illite–smectite occur in rock salt of Eggenbur

AbstractDetrital, volcanic and diagenetic origins have been used to explain the smectite clay assemblage that characterizes the Upper Cretaceous Chalk of Europe. To further the understanding of how clays of different origins may have converged to this characteristic clay mineral assemblage a new approach is put forward for their investigation. This is based upon (1) the correlation that exists between the trace element and stable isotope geochemistry of the calcite cements preserved within Chalk brachiopods and the various diagenetic phases of early lithification and cementation recognized in

The Vejle Fjord Formation comprises three members; the Brejning Clay, the Vejle Fjord Clay, and the Vejle Fjord Sand (Late Oligocene-Early Miocene). The lower part of the Brejning Clay was laid down in a shelf environment with a reduced influx of siliciclastic detritus. This resulted in deposition of clay minerals enriched in iron. The early diagenesis was characterized by pyrite and siderite formation within an anoxic sedimentary environment which was established due to degradation of organic matter just below the water/ sediment surface.

Abstract Phyllic and argillic alteration at Bingham consists of smectite, sericite, and kaolinite. X-ray diffraction and microprobe studies show that sericite in these alteration assemblages is illite interstratified with 10 percent or less smectite. Illite occurs as a replacement of plagioclase phenocrysts, in veins, and as pervasive disseminations in the rock along with smectite and minor kaolinite. The illite/smectite interstratification is a mixture of 1M and 2M polytypes and generally contains more smectite in the finer size fractions. Structural formulae for the illite show less K and Al

Natural radioactivity in rocks is usually the result of the presence of natural isotopes: potassium – 40K, uranium – 238U, 234U, 235U, and thorium – 232Th and their decay products. Initially contained in acid igneous rocks, these isotopes are released through weathering processes and subsequently transported to sedimentary sites, where they primarily accumulate by adsorption onto clay mineral particles. Direct measurements of potassium, uranium, and thorium activity in sedimentary rocks provide crucial insights into their geochemistry and mineral content. Methods proposed the use of gamma ray
