Ultraslow spreading at mid-ocean ridges limits melting due to on-axis conductive cooling, leading the prediction that peridotites from these are relatively fertile. To test this, we examined abyssal Gakkel Ridge, slowest ridge in global ocean system. Major and trace element concentrations pyroxene olivine minerals reported for 14 dredged peridotite samples Sparsely Magmatic (SMZ) Eastern Volcanic (EVZ) Zones. We observe large compositional variations among same dredge dredges close proximity...

Endolithic microbial communities survive nutrient and energy deficient conditions while contributing to the weathering of their mineral substrate. This study examined composition fully serpentinized weathered rock from 0.1 6.5 m depth at a site within Khalilovsky massif, Orenburg Region, Southern Ural Mountains, Russia. The includes major content serpentinite family (mostly consisting lizardite chrysotile), magnesium hydrocarbonates (hydromagnesite with lesser amounts hydrotalcite...
In the mantle, base metal sulfides have been proposed as main host for many chalcophile and siderophile elements. This includes elements such Pb, Se, Te, which are often used tracers of processes ranging from planetary accretion to mantle melting. We present in situ measurements these elements, along with As, Sb, Ag, Au, Cl, abyssal peridotite provide constraints on storage mantle. A total 152 11 peridotites 1 pyroxenite Gakkel Southwest Indian ridges were analyzed. The pentlandites, some...
