nickel occurs in this terrestrial minerals
garnierite, millerite, niccolite, pentlandite, and
pyrrhotite;

into various shades of blue, gray to black as it approaches the bedrock.
The higher ore grade is
believed to be due to the downward migration of nickel which eventually settles along
the numerous cracks
e ubiquitous green coatings along fractures
are often due to garnierite, a high grade hydrous nickel silicate belonging to the
serpentine group of minerals
Saprolite zone
associated with chromitites and platinum group
elements (PGE)
average grade of from 0.23 to 0.47 percent Ni.

Magmatic nickel sulfide

inclusions in the chromite grains
occurs in narrow silicified zones in serpentinite
rock and in rocks immediately adjacent to it.
