alteration of ophiolitic ultramafic rocks, formation of listwaenite and associated mineralization are interesting phenomena of metallogeny of khoy ophiolite. it seems that the hydrothermal circulations responsible for mercury mineralization were derived from geothermal systems caused by intermediate to acidic magmatism in neogene-pleistocene time. reactivation of brecciated serpentinite with hy...

Annotation. The article is devoted to the development of an effective technology for processing serpentinite ores from Bozymchak deposit in Kyrgyz Republic. Based upon analysis mineralogical, physical and chemical parameters ore, authors set reasons decrease technological indicators existing concentrator determine concentrating properties reviewed resistant material by applying methods intensif...

Geological processes at subduction zones control seismicity, plutonism and volcanism, geochemical cycling between the oceans, crust, mantle. The down-going plate experiences metamorphism, associated dehydration fluid flow alters physical properties of interface mantle wedge, as well controlling composition material descending into Any direct study slab evolution during is inhibited by prohibiti...
