Contact us· Recent work proposed that hydrous partial melting of mafic rocks is an alternative mechanism to form plagiogranites (Koepke et al., 2007). The proposed magmatic link is the key of to the interpretation of Beard et al. (2002), who equated the U-Pb data on a single zircon from an albitite clast to the intrusion age of the kaersutite dike. Out of ...
Contact usA pegmatite is an igneous rock, formed by slow crystallization at high temperature and pressure at depth, and exhibiting large interlocking crystals usually greater in size than 2.5 cm (1 in).Most pegmatites are intrusive rocks found in sheets of rock (dikes and veins) near large masses of igneous rocks called batholiths.. The word pegmatite derives from Homeric Greek, πήγνυμι (pegnymi ...
