The new model calculates the amount of free hydrogen gas produced and stored beneath the seafloor based on a range of parameters - including the ratio of a site's tectonic spreading rate to the thickness of serpentinised
rocks that might be found there, Science Daily reported.
A relatively easy climb to the base of this Simsima exposure begins with a traverse across dark serpentinised
About 8090% of the peridotite in the study area is serpentinised
This structure underwent a change of the insular arc type starting in the Lower Cretaceous and contains metamorphic rocks [green schist, metavulcanites and serpentinised
peridotites, and blue and serpentine schist in the northern mountains] (Lewis and Draper 1990, Bowin 1975, 1966; Bracey and Vogt 1970).
The parent material of the very deep red, clayey soil is highly fractured and serpentinised
ultrabasic rock (peridotite) of Upper Cretaceous origin.
Under the typical weathering profile of this serpentinised
peridotite, the rock has been hydrated prior to laterisation and the permeating groundwater solutions have penetrated the hydrated rock.
A petrological examination of four rock samples collected during 2002 from the Exploration Licence 50 kilometres north of the WMC/ Falcon ground , has identified them as being possible silicified and ferruginised ultrabasic cap rocks which may have been serpentinised
A small lens of serpentinised
mass occurs within the schists outcropping along the road just to the south of the main mass and MMT.
The Touban hill is an intrusive basic-ultrabasic elongated plug-like body that contains two petrographically distinct facies, an ultrabasic peridotitic-type partly serpentinised
facies and a gabbroic facies with little mineral alteration.
