Mineralogy and geochemical affinities of bentonites from Kapıkaya (Eskişehir, western Turkey)
Abstract There are numerous bentonite deposits, formed by the alteration of volcanic rocks, in the Kapıkaya area (Eskişehir, western Turkey). These deposits can be classified into three groups
Spanish Bentonites: A Review and New Data on Their Geology, Mineralogy, and Crystal Chemistry
A review and a synthesis of the geological, mineralogical, and crystal chemical data available in the literature on active Spanish bentonitic exploitations were done, and at the same time, new data
Diagenetic evolution of the volcaniclastic deposits: an example from Neoproterozoic Dokhan Volcanics in Wadi Queih basin, central Eastern Desert, Egypt
Wadi Queih basin hosts a ∼2,500-m thick Neoproterozoic volcanoclastic successions that unconformably lie over the oldest Precambrian basement. These successions were deposited in alluvial fan,
Formation of a hydrothermal kaolinite deposit from rhyolitic tuff in Jiangxi, China
The Longmen kaolinite deposit is one of the largest hydrothermal clay deposits of Ganxi volcanic basin (northern Wuyi Mountain area, China). The pristine host rocks are rhyolitic crystal-vitric tuff
The origin and implications of clay minerals from Yellowknife Bay, Gale crater, Mars
TLDR
Mineralogical evidence of the persistence of benign aqueous conditions at YKB for extended periods indicates a potentially habitable environment where life could establish itself andThermodynamic modeling indicates that the production of authigenic magnetite and saponite at surficial temperatures requires a moderate supply of oxidants, allowing circum-neutral pH.
Volcanic Holocrystalline Bedrock and Hydrothermal Alteration: A Terrestrial Analogue for Mars
Clay minerals have been detected on Mars to outcrop mainly as alteration of ancient bedrock, and secondarily, as deposition from aqueous environments or interlayered with evaporitic deposits on Mars.
Significance of the tuffaceous beds associated with the Bijaigarh Shale of the Kaimur Group, Vindhyan Supergroup, Central India and their correlation with tuffs in other contemporaneous Proterozoic basins
Bijaigarh Formation is lithologically heterogeneous with grain size varying from fine to medium sand to clay. About ~1 m thick tuffaceous beds of rhyolitic to rhyodacitic nature, sandwiched between
Elemental Compositions of Smectites Reveal Detailed Sediment Provenance Changes during Glacial and Interglacial Periods: The Southern Drake Passage and Bellingshausen Sea, Antarctica
Variations in clay mineral assemblages have been widely used to understand changes in sediment provenance during glacial and interglacial periods. Smectite clay minerals, however, have a range of
The mineralogy of paleosols in the Marilia Formation and their importance in the environmental evolution of the Maastrichtian of the Bauru Basin in southeastern Brazil
Soils and paleosols reflect the complex interplay between sedimentation, erosion and non-deposition. An analysis of the mineralogical components of paleosols is critical for the reconstitution of the
