The change of minerals or geologic texture in protoliths or pre-existing rocks that occurs without the melting of protolith into liquid magma is known as Metamorphism. This change occurs principally ...

CLAY mineralogical analyses have been important in sedimentology, in studies of the genesis and behaviour of soils and in ceramics. The effect of high temperatures on clay minerals has also often been ...

Contact metamorphism resulting from intrusion of the South Mountain Batholith (SMB) at 372 Ma produced textural and mineralogical changes in rocks of the Meguma Supergroup. A detailed petrographic ...
