Abstract

Podiform chromite deposits occur in peridotite and mafic complexes of alpine type, and are tabular, pencil-shaped, or irregular in form. In contrast with stratiform deposits, whose textures and structures reflect crystal settling and suggest analogies with sedimentary rocks, the textures of podiform deposits reflect extensive flowage, under magmatic conditions, as a stiff crystal mush and suggest analogies with metamorphic rocks. Though the orebodies as entities may be parallel or discordant with wall-rock layering, interval linear and planar elements are generally parallel with those of the country rock. The relationships of the various structural elements are critical exploration guides.
