granitoid rocks: coarse grained granodiorites and porfiroidical granodiorites. Largery granular gra-nodiorite is mainly gray through which can be found dark gray patches of colored mineral. It con-sists of coarse grained minerals, with grain diame-ter 5 – 6 mm, which is massive and hard texture. It has hypidiomorphic granular structure and

(1999). According to those workers four tectonic units make up the Menderes nappes. The three structurally highest units, which are, from top to bottom, the Selimiye, the C¸ine and the Granitoid rocks cover about 60.000 km² of the Egyptian Shield (Hassanen et al., 1996). Granitic rocks form ~50% of the basement in the North Eastern Desert of Egypt and southern Sinai.

By stressing the various techniques used to determine the petrogenic history of granites, and by bridging the gap between undergraduate and research texts, this book provides a clear understanding of the Host granitoid rocks are part of the Klein Creek pluton . The largest deposits are Baultoff , which has a 2 km2 area of altered rock , and Horsfeld , which has a 1 . 2 km2 area of altered rock .

granitoid rocks are formed by magma mixing between 70%–90% melts derived from partial melting of the Neoproterozoic basement rocks of the SQB and 10%–30% mantle-derived maﬁc melts with minor involvement of Archean to Paleoproterozoic old basement materials of the SQB. The Zhashui granitoid rocks exhibit high K 2O, Rb, A/CNK, AMF(Al 2O

Granitic rocks or granitoids, i.e., granular igneous rocks that generally The oxidation state of granites is also critical, with Cu-Au-. Mo associated with oxidised rocks and Sn with reduced rocks.

W. DODGE, H. T. MILLARD, JR., and H. N. ELSHEIMER GEOLOGICAL SURVEY PROFESSIONAL PAPER 1248 A geochemical study of the lateral compositional variations in granitoid rocks across the central Sierra Nevada batholith granitoid rocks: coarse grained granodiorites and porfiroidical granodiorites. Largery granular gra-nodiorite is mainly gray through which can be found dark gray patches of colored mineral. It con-sists of coarse grained minerals, with grain diame-ter 5 – 6 mm, which is massive and hard texture. Granitoid rocks can be subdivided in two main ways: (1) by referring to geographically contiguous bodies (batholiths); and (2) by reference to groups of rocks which have similar chemistry, mineralogy, and usually age (suites).
