The Dogantarla-Aksaray area is situated in western part of the CAVP. This province contains nine (9) different ignimbrite levels, for which a Late Miocene age is indicated by vertebrates as well as K/...
Palygorskite in Miocene mudstones, palustrine limestones and calcretes from the Esquivias locality (Madrid Basin, Spain) has been analyzed by X-ray diffraction, infrared spectroscopy, scanning electro...
the mineralogical characteristics of palygorskite from the Lower Miocene Euphrates Formation and the Middle Miocene Fat’ha (Lower Fars) succession in north and northwestern Iraq were studied by X-ray ...
The playa-mudflat facies under investigation are found in the Gemerek Basin (Sivas, T黵kiye). This Miocene basin is bordered by the Akdag Metamorphics (Paleozoic) to the N-NW, the Elmal齞ag Volcanic Roc...
Clay mineralogy of the Miocene successions taken from northern Iraq constitute an important paleoenvironmental indication for the evolution of these sediments. Palygorskite is a common mineral especia...
Abstract: Clay mineral diagenesis in the Niigata basin is documented by mineralogical and chemical analysis of clay minerals from cuttings from the Shinkumoide SK-1D (SSK-1D) well which is characteriz...
Abstract: The oxygen and hydrogen isotope compositions of volcanic ash layers from coastal outcrops of the Miocene Monterey Formation elucidate the progressive burial diagenesis of glass to bentonite ...
Abstract: Clay mineral compositions from 2 paleosol profiles (Chu-Wan, CW, and Shiao-Men Yu, SMY, profiles) on the late-Miocene sediments in Penghu Islands (Pescadores), Taiwan, are characterized by r...
Abstract: Magnesite pebbles in Miocene lacustrine conglomerates in northwest Turkey have been partially to totally replaced by sepiolite. Only 5% of the magnesite pebbles have been converted to essent...
Abstract: In the Pohang area of Korea, heulandite occurs as cements in conglomerate and sandstone of a Miocene marine fan-delta system resting on Eocene dacitic volcanics. Three types of heulandite ce...
The grey-green peloids from the Miocene period to Recent fine-grained deposits on the continental shelf close to Congo-Zaîire River mouth were studied by X-ray transmission diffractometry (XRD),...
The Sepfilveda-Ayll6n Basin (SAB) was an episodically closed Miocene basin adjacent to the Tertiary Duero Basin (northern Spain). The sediments studied here represent a depositional system developed f...
This study assesses the distribution of Al and Fe in mixed-layer illite/smectites (I/S) in shales undergoing burial diagenetic changes, using evidence from 27Al NMR, XRD, and chemical analyses. Sample...
Empirical relationships between clay mineral transformations and temperature provide a basis for the use of clay minerals as geothermometers. Clay-mineral geothermometry has been applied mainly to dia...
Mordenite occurs in hydrothermally altered rhyolitic volcanic rocks at the margin of a Late Miocene lake basin on the island of Samos, Greece. The mordenite was identified by its X-ray powder diffract...
