Clay-mineralogy study of Taiwanese river-mouth sediments, recent deep-water seafloor sediments around Taiwan, along with collected from the Tainan shelf edge, have been investigated to access source and transport detrital fine-grained sediments. We determined clay mineralogy in both hemipelagites turbidites top 50 cm deep-sea sediment cores infer how are dispersed through river-fed turbidity cu...

Introduction: For nearly a decade, the international program of Mars exploration has been guided by a remarkably useful framework that describes how Mars' environmental conditions have evolved in the context of time-dependent changes in the mineralogy of rock and regolith deposits at the Martian surface [1]. Built on the basis of observations by the OMEGA spectrometer onboard ESA's Mars Express...

[1] The slip behavior of major faults depends largely on the frictional and hydrologic properties of fault gouge. We report on laboratory experiments designed to measure the strength, friction constitutive properties, and permeability of a suite of saturated clay-rich fault gouges, including: a 50:50% mixture of montmorillonite-quartz, powdered illite shale, and powdered chlorite schist. Fricti...

El’gygytgyn Crater Lake, NE Siberia was investigated for sedimentological proxies for regional climate change with a focus on the past 65 ka. Sedimentological parameters assessed relative to magnetic susceptibility include stratigraphy, grain size, clay mineralogy and crystallinity. Earlier work suggests that intervals of high susceptibility in these sediments are coincident with warmer (interg...
