From theCambridge English Corpus Thus,dolomitevein formation and haematite precipitation were two distinct events, which likely record different conditions.

From theCambridge English Corpus In the molasse sample,dolomiteis present while calcite is absent. From theCambridge English Corpus The main constituents are quartz and calcite, whereas plagioclases, clay minerals and dolomites are less abundant. From theCambridge English Corpus The sulphide phase involves the precipitation of both fine-grained and coarsely crystalline sulphides (chalcopyrite, sphalerite, galena, pyrite) with quartz,dolomite, calcite, malachite and pink baryte.
