This paper describes unusual graphite-sulfide deposits in ultramafic rocks from the Serranía de Ronda (Spain) and Beni Bousera (Morocco). These deposits occur as veins, stockworks and irregular masses, ranging in size from ...
The isotopic composition of carbon and oxygen was determined by two techniques in whole-rock samples and single grains of carbonates from rocks of various morphogenetic types from the Aldan Shield. The isotopic values ...
