Metamorphic rocks in SW Arak composed from two groups including regional and contact metamorphism. Regional metamorphic rocks are composed of slate, phyllite and micaschists and locted in green-schist facies and contact metamorphic rocks are composed of spotted schist and hornfels respectively. Mineralogically, these rocks are composed of quartz, chlorite, muscovite, biotite and cordierite. Pet...
Northeast Queensland contains multiple slices of mafic–ultramafic units, strung out along regional faults that mark major tectonic boundaries. One such complex is the Cowley Ophiolite Complex, which situated Russell-Mulgrave Fault. The Complex a differentiated composed gabbro, chlorite schist, anthophyllite schist and serpentinite. We interpret alteration assemblages observed throughout reflect...
for the first time, an unusual assemblage of talc-phengite-chlorite-k-feldspar was found in quartz schists from the sanandaj-sirjan zone in the nahavand area in western iran. the talc-bearing quartz schists occur as small bodies or lenses within pelitic schist layers and contain talc, phengite, chlorite, k-feldspar and quartz as major mineral constituents with subordinate amounts of calcite ...
Insights into a Mineral Resource Chlorite Mica Carbonate Schist by Terahertz Spectroscopy Technology
Nowadays, the mineral resources formed by geological processes have been effectively utilized with boom exploration of novel technologies. Traditional analytical methods, such as X-ray Fluorescence, diffraction, and Scanning electron microscopy, remain commonly used approaches for resource detection. However, recent accelerations in terahertz component progress promoted researchers to discover ...
[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...
The submarine volcanic rocks of Totmaj volcano-sedimentary sequence, located at 25 Km southeast of Kashan city, have suffered extensive non-uniform propylitization. Based on field and petrographical studies, the volcanic rocks can be classified into three alteration zones: chlorite-epidote zone, epidote zone and hematite zone. The secondary hydrothermal minerals formed in the volcanic rocks inc...
Metapelites of the Do Chah complex (SE Shahrood) are composed of micaschist, garnet micaschist, chloritoid schist and garnet-bearing gneiss. In the highest degree of metamorphism, metapelites have been affected by partial melting, resulting as granitization. A significant part of these rocks, imposed by compressional tectonic regime and show typical evidence of plastic deformation and intensive...
HP/LT metabasite rocks can preserve some evidences of tectonic and geochemical processes of a subduction zone. Sabzevar Ophiolite and metabasites which are located at the north of Central Iranian Microcontinent Block (CIM) have preserved such evidences. The metabasites are fossil oceanic crust of Neotethys-related basin. Metabasites are composed of glaucophane schist, amphibolite and greenschis...
