Abstract

From a huge belt of peridotites, situated in the province of Muğla - SW
Turkey, the general tectonic setting, age relations, composition and structure are discussed.
In this belt many chromite deposits are scattered, some of them having economical importance.
It is shown that differences of chromites, calculated from analyses of chromium ores, make
it possible to distinguish between basal-middle and upper zone of the ultrabasic intrusion.
This observation is of practical importance inasmuch as economical chromite deposits are
mostly restricted to the basal - lower middle part of the peridotites.
It also may be used to solve tectonic problems where alpine mountain building, resulting in
overthrusts respectively thrust faults and posterior faulting, obliterated primary-magmatic relationship.
