TLDR
The Tso Morari serpentinites in the Ladakh area, northwest Himalaya, originated from the forearc mantle overlying the northward subducting Neo-Tethys lithosphere and the margin of the Indian continent as mentioned in this paper.About:

Journal ArticleDOI
Geochemistry of subduction zone serpentinites: A review
TL;DR: A review of the geochemistry of serpentinites, based on the compilation of ~900 geochemical data of abyssal, mantle wedge and exhumed serpentinite after subduction, is presented in this paper.

The role of serpentinites in cycling of carbon and sulfur: Seafloor serpentinization and subduction metamorphism
Jeffrey C. Alt,Esther M. Schwarzenbach,Gretchen L. Früh-Green,Wayne C. Shanks,Stefano M. Bernasconi,Carlos J. Garrido,Laura Crispini,Laura Gaggero,José Alberto Padrón-Navarta,Claudio Marchesi +9 more
TL;DR: In this paper, the authors summarize the uptake of carbon and sulfur during serpentinization of seafloor peridotites, and discuss the fate of these volatiles during subduction of serpentinite.

Recycling of water, carbon, and sulfur during subduction of serpentinites: A stable isotope study of Cerro del Almirez, Spain
Jeffrey C. Alt,Carlos J. Garrido,Wayne C. Shanks,Alexandra V. Turchyn,José Alberto Padrón-Navarta,Vicente López Sánchez-Vizcaíno,Vicente López Sánchez-Vizcaíno,Maria Teresa Gomez Pugnaire,Claudio Marchesi +8 more
TL;DR: In this article, the authors use the concentrations and isotope compositions of water, carbon, and sulfur in serpentinites and their dehydration products to trace the cycling of volatiles during subduction.
Journal ArticleDOI
Serpentinites act as sponges for fluid‐mobile elements in abyssal and subduction zone environments
TL;DR: In this paper, trace element analysis of oceanic serpentinites from the Mid-Atlantic Ridge and the Greater Antilles (Cuba, Dominican Republic) shows that all serpentine minerals are enriched in fluid-mobile elements (FME: As, Sb, B, Li, Cs, Pb, U, Ba, Sr).

The composition of the Earth
William F. McDonough,Shen-Su Sun +1 more
TL;DR: In this paper, the authors compared the relative abundances of the refractory elements in carbonaceous, ordinary, and enstatite chondritic meteorites and found that the most consistent composition of the Earth's core is derived from the seismic profile and its interpretation, compared with primitive meteorites, and chemical and petrological models of peridotite-basalt melting relationships.
Journal ArticleDOI
A review of the source, behaviour and distribution of arsenic in natural waters
TL;DR: The scale of the problem in terms of population exposed to high As concentrations is greatest in the Bengal Basin with more than 40 million people drinking water containing ‘excessive’ As as mentioned in this paper.

Distribution of the Elements in Some Major Units of the Earth's Crust
Karl K. Turekian,K. H. Wedepohl +1 more
TL;DR: A table of abundances of the elements in the various major units of the Earth's lithic crust with a documentation of the sources and a discussion of the choice of units and data is presented in this article.

The chemical composition of subducting sediment and its consequences for the crust and mantle
Terry Plank,Charles H. Langmuir +1 more
TL;DR: This article evaluated subducting sediments on a global basis in order to better define their chemical systematics and to determine both regional and global average compositions, and then used these compositions to assess the importance of sediments to arc volcanism and crust-mantle recycling, and to re-evaluate the chemical composition of the continental crust.

Composition of the Earth
TL;DR: In this article, the authors reported that the resulting densities in the lower mantle are in good agreement with shock-wave measurements on rocks having FeO contents in the range 10 ± 2% by weight.
