DOI: 10.1007/s00126-020-01007-2
Abstract: The Troodos ophiolite Cyprus hosts the on-land analogue for actively forming mafic, Cu-rich, or Cyprus-type VMS deposits. In addition to high-temperature (> 350 °C) sulfide mound-related mineralization, other fossil seafloor mineralizing systems are known to operate, including… read more here.

DOI: 10.1016/j.gca.2020.11.001
Abstract: Abstract Recent studies of serpentine-free, spinel peridotite xenoliths from the mantle lithosphere beneath the active Kamchatka and West Bismarck arcs have shown that these rocks are enriched in silica and highly depleted in incompatible elements… read more here.

DOI: 10.1016/j.oregeorev.2020.103742
Abstract: Abstract The Okinawa Trough (OT), is a back-arc basin where rifting is in its initial stages, and where hydrothermal fields (HTFs) have developed above terrigenous sediments and volcaniclastics layers of variable thickness. The source of… read more here.

DOI: 10.1080/10426914.2020.1762210
Abstract: ABSTRACT The SiO2 varieties of low temperature other than quartz play an important role in the composition of many archeological tools, products, byproducts, and raw materials. We have encountered several SiO2 species, ranging from Paleolithic… read more here.
