Quartz monzonite - Wikipedia
Quartz monzonite is an intrusive, felsic, igneous rock that has an approximately equal proportion of orthoclase and plagioclase feldspars. It is typically a light colored phaneritic (coarse-grained) to porphyritic granitic rock. The plagioclase is typically intermediate to sodic in composition, andesine to oligoclase.
Adamellite - Oxford Reference
6 天之前 · A rock of granitic composition (see granite) characterized by the presence of quartz, plagioclase feldspar, and potassic feldspar (see alkali feldspar) accompanied by biotite and/or hornblende. The two feldspar types occur in approximately equal proportions, the plagioclase composition lying within the oligoclase range.
Adamellite | Quartz monzonite - Definition - GeologyHub.com
What is Adamellite? Quartz monzonite or adamellite is an intrusive, felsic, igneous rock where two feldspar (Plagioclase and Alkali Feldspar) are approximately equal in quantity. Rest of the mineral constituent are quartz, biotite or hornblende. It is typically a light colored phaneritic (coarse-grained) to porphyritic granitic rock.
What Is Adamellite | Adamellite Features - Compare Nature
Adamellite is a coarse-grained porphyritic igneous rock, a variety of Monzogranite and dominated by phenocrysts of orthoclase in a granular groundmass of perthite, plagioclase and quartz. 1.2 History. 1.2.1 Origin.
