Introduction. 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 is associated with both series but is Its characteristic failures are debris flows, debris avalanches, and debris slides. Saprolite is residual granitic rock that is vulnerable to rota- tional slides and slumps Archaean granitoid rocks of the Kaapvaal Craton have formed the subject of a number of investigations aimed at determining the geological, geochemical and Peraluminous granitic rocks are magmatic rocks that contain quartz, po tassic feldspar and/or sodic plagioclase, and one or more aluminum-rich minerals; thus One of the most outstanding characteristics of some granodioritic to granitic rocks is the presence of K-feldspar megacrysts.

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.

Nappes in the middle parts of the Caledonian tectonostratigraphy in … Granitoid rocks of this age in eastern Labrador belong to two groups. One is a series of discrete alkali-feldspar syenite bodies in the Makkovik Province that have already been addressed (see Section 6.5). The other is the Eagle River complex in the Grenville Province, which is the topic of this chapter. A number of granitoid bodies and low-grade metasedimentary and metavolcanic rocks of the Neoarchean Dharwar Supergroup (locally termed as Goa Group) are exposed in the north-westernmost part of the Dharwar Craton, near Goa and northern Karnataka (Fig. 30.24) (Dhoundial et al., 1987; Devaraju et al., 2007).These granitoids yielded whole-rock Rb–Sr age of ∼2.6 Ga and are variably interpreted 2021-01-09 regression to determine mineral modes of granitoid rocks Christoph Hecker Department of Earth Systems Analysis, Faculty of Geo-Information Science and Earth Observation, University of Twente, PO Box 217, NL-7500 AE Enschede, Netherlands (hecker@itc.nl) John H.
