It also occurs as a minor component of wall-rock alteration of mafic rocks, and replacing biotite in the outer zone of alteration associated with vein deposits (Lindgren and Ransome, 1906; Thompson et al., 1985; Thompson, 1992).
Roscoelite occurs mostly as a product of wall-rock alteration, replacing plagioclase and biotite in the inner alteration zone of veins (e.g.
Serpentine is a product of wall-rock alteration replacing olivine in mafic rocks of the district (e.g.
