Serpentinite, a metamorphic rock of modest appearance, has not only been a material revered by ancient cultures, but modern ...

Submarine hydrothermal vents above serpentinite produce chemical potential gradients of aqueous and ionic hydrogen, thus providing a very attractive venue for the origin of life. This environment was ...

Figure 1: Distribution of serpentinite along the SAF creeping section. The serpentinite contains numerous calcite- and some quartz-filled veins, possibly resulting from focused fluid flow within the ...

Starting today I will be doing weekly posts for the San Francisco Bay Area public TV/radio station KQED’s community science blog. They produce a television program called QUEST that highlights greater ...

In the upper two panels show modelling results of the contamination of depleted mantle (DM, yellow stars) by (1) serpentinite-derived fluids, and by (2) fluids derived from the slab crust materials.

A new study has identified serpentinite -- a green rock that looks a bit like snakeskin and holds fluids in its mineral structures -- as a key driver of the oxygen recycling process, which helped ...

The purpose of this study was to 1) demographically monitor the only remaining natural population of the rare serpentinite annual plant Acanthomintha duttonii (Lamiaceae); 2) attempt to reintroduce a ...

The serpentinite-dominated mélange was initially formed at the slab-mantle interface, which is primarily composed of forearc serpentinite along with minor sediments and possibly other slab-derived ...

STATEN ISLAND, N.Y. -- The truly oldest rocks on the Island can't be seen on the surface. These include 575-million-year-old Fordham gneiss, Manhattan schist, granite pegmatite and Inwood marble, ...
