The Acidic Components of Metamorphic Massifs: A Perspective on Geochemistry and Mineralogy
Abstract
In this study, we attempted to interpret the geochemistry and mineralogy of acidic magmatite samples in the vicinity of Yolcular, approximately 140 km southeast of Bitlis Province, within the context of regional geology. Acidic magmatites are high-silica content igneous rocks that can have volcanic or plutonic origins. The average mineral composition of acidic magmatites such as aplite and metagranite includes alkali feldspar, plagioclase, quartz, biotite, and hornblende. Geochemical analyses indicate that these rocks are composed of granodiorite and formed through the differentiation of granite-granodiorite magma. The fractional crystallization process also suggests the modification of toleyitic and calc-alkaline granitic magma. Particularly, fractional crystallization plays a significant role in the formation of aplite veins within the metamorphic massif. This can be observed through high LaN/YbN, Rb/Sr ratios, low Sm/Nd, K/Rb, and Sr/Ba ratios. The variations in trace element ratios indicate the influence of fractional crystallization associated with partial melting on the upper continental crust. Acidic magmatites have been affected by regional metamorphism and cataclastic metamorphism, as evidenced by the preferred orientation, microfolds, and foliation observed in biotite minerals. Metamorphism represents amphibolite facies conditions that affect all units within the metamorphic massif.
