احصل على السعرNow, with fairly mild chemical processing that MIT's Davide Ciceri describes as 'accelerated weathering in an autoclave', Ciceri and his colleagues think they can change this. Their processing method removes the need for costly and energy and water intensive separation and recrystallisation processes, explains fellow team member Antione Allanore.
احصل على السعرThe various textural types of Seqi dunite also contain magnetite inclusions, and previous serpentinization of these rocks can therefore not be excluded. However, it should be noted that the oxygen isotope compositions of the Seqi olivine is within the range of magmatic rocks, which places constraints on the degree of potential early serpentinization.

Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite bearing rocks are altered by heat or weathering.
