A wide range of plutonic rocks, ranging from mafic to felsic compositions, including various gabbros, diorites, tonalites, granodiorites, monzogranites, syenogranites and leucocratic granitoids, occur in the Alvand plutonic complex, Sanandaj-Sirjan zone, Iran. Age of this complex is middle Jurassic. In this complex, granitic and dioritic rocks occur as major constituents. Granites contain plagi...

base and precious metals associated with porphyry, epithermal and acid sulphate or high-snlphidation hydrothermal systems (Panteleyev, 1992; Panteleyev and Koyanagi, 1993, 1994). The majority of these systems are associated with the Early to Middle Jurassic Island Plutonic Suite and Early Jurassic B O M ~ Group rocks. The regional mapping component of this study focused primarily on potential t...

The bio-weathering process contributes majorly in the physical shaping of earth’s surface. weathering mineral is coupled to formation new minerals and release bio-available nutrients for flora as well microbial communities. Granites from Eastern Dharwar Craton (EDC) India are felsic plutonic igneous rock composed nutritive minerals. major elemental composition granite such that, it forms an anc...

In a study based on Pb isotopes, it has been shown that the formation of gold-sulfide mineralization in Early Proterozoic gabbros Northern Ladoga region is associated with different tectonic phases. This conclusion comparative isotopic data for feldspars and lead sulfides two intrusions; Velimäki Alattu-Päkylä. The investigated intrusions have similar geological settings at junction Svecofennia...

Abstract Pegmatite fields within granite plutons are commonly considered to have formed from residual melts of their host. This is not always true as demonstrated by the Tysfjord gneiss and its two groups pegmatites. The gneiss, exposed in a tectonic window Caledonides northern Norway, part transscandinavian igneous belt (TIB) that includes several phases granitic magmatism. In Hamarøy area (Dr...

The Kuh-e Mish plutonic complex (KPC) is located about 30 km south of Sabzevar. Based on tectonic division, it is part of Sabzevar zone. The Stratigraphic units of the area are conglomerate, tuff, and sandstone of the Paleogene, radiolarites, andesite and tuff unit of Upper Cretaceous. This collection consists of two plutonic rocks types. (1): The granitoid complex of northern Kuh-e Mish which ...
