ALLOCHTHONOUS MARBLES IN HIGH-GRADE METAMORPHIC TERRANES (A CASE STUDY OF OLKHON TERRANE, WEST BAIKAL AREA, RUSSIA)

https://doi.org/10.5800/GT-2017-8-3-0291

Abstract

Marbles are common constituents of high-temperature (HT) metamorphic terranes and shields. They have been traditionally considered as indicators of sedimentary or volcanic origin of related rocks involved into metamorphism which erases the primary features of the protoliths. This approach is correct in most cases, but carbonate and silicate-carbonate rocks, which often make linear bodies, may be allochthonous in some structurally and compositionally complex metamorphic terranes, as in the case of the Olkhon terrane.
