In-situ permeability of the Median Tectonic Line (MTL) fault zone in Mie Prefecture, southwest Japan, was estimated using hydraulic tests and groundwater pressure observations in two boreholes. The screen depths in Holes 1 and 2 are located, respectively, in a major strand of the MTL fault zone within the Sambagawa metamorphic rocks and a branching fault developed in the hanging wall of the MTL...

The Upper Jurassic Galice Formation and parts of its 164 to 162 Ma Josephine ophiolite basement, both of the western Klamath terrane (WKT) have been suggested to constitute lower grade equivalents of the Condrey Mountain Schist (CMS) . The high P/T CMS is exposed through a window within the Rattlesnake Creek terrane (RCT) which has been thrust westward over the WKT. The Ga lice-CMS correlation ...

The morphology of resorbed diamond crystals is a valuable source information on the composition and ascent rate kimberlite magmas, as well possible redox conditions in protolith. Previously, resorption was thoroughly investigated at P–T–fO2 parameters magma ascent. In this study, we using unaltered group I model carbonatite that are typical peridotite magmas subcontinental lithospheric mantle. ...

In the Southern São Francisco Craton near Itapecerica (Minas Gerais – Brazil) occurs a supracrustal succession of rocks, varying from bottom to top by quartzite, graphite schist, khondalitic paragneiss and banded iron formation whose protoliths are oceanic basin with ages in context Rhyacian-Orosirian orogeny. Amphibolite metaultramafic bodies occur associated this succession. Mineralogical tex...

the protoliths of metamorphosed argillaceous rocks from the garmichay area in the east azerbaijan province of nw iran were clay-rich sediments of reworked nature, originating most likely from an andesite to andesite-basalt source and deposited in an active continental margin tectonic setting. the protoliths of the garmichay metapelites experienced low to moderate chemical weathering. andalusite...
