Three granitoid types are recognised in the Famatinian magmatic belt of NW Argentina, based on lithology and new geochemical data: (a) a minor trondhjemite–tonalite–granodiorite (TTG) group, (b) a metaluminous I-type gabbro-monzogranite suite, and (c) S-type granites. The latter occur as small cordieritic intrusions associated with 1-type granodiorites and as abundant cordierite …
Granite is a durable and heat-resistant natural stone that is suitable for outdoor use. It can withstand high temperatures and is not affected by extreme weather conditions such as UV rays, direct sunlight, or heat.
Granite is a natural stone formed from volcanic magma and is mainly composed of quartz, feldspar, and mica. It has a grainy appearance with visible patterns and variations in color. …
During the Early Carboniferous, significant intracontinental magmatism was developed in the retro-arc region of the SW margin of Gondwana between ca. 27° and 31°S. This magmatism consisted of metaluminous to weakly peraluminous A-type granites, strongly peraluminous A-type granites (A- to S- hybrid granitoids) and, to a lesser extent, (sub-)volcanic …

The inconsistent distribution of mineralization of late Mesozoic granites in the East Qinling orogenic belt (EQOB) remains to be explained. The EQOB formed as a result of the Triassic collision between the NCC and YB along the Mianlue suture (Wu and Zheng, 2013), and this area contains widespread late Mesozoic granites.All of the large porphyry (−skarn) Mo …
The geochemistry of K-feldspar for K, P, Sr, Ba, Rb, Cs, Ga, and of muscovite for the same elements plus Nb and Ta, was used for proving the parental relationships of S-type granites and LCT (Li, Cs, Ta) rare-element pegmatites in the southernmost pegmatitic field of the Pampean pegmatite province in Argentina.

The two-stage Nd and Hf model ages of these granites suggest that continental crust older than 2.80 Ga is preserved beneath the TSGT.In combination with previous data from the region, it is noted that, apart from rapid crustal growth at ~ 2.7 Ga, other additions of mantle-derived magma, such as minor 2.6–2.5 Ga sanukitoids, siliceous high-Mg basalts (SHMBs) …

The petrogenetic processes proposed for the generation of A-type granites are diverse: (1) differentiation of mantle-derived basaltic magmas (± crust assimilation) (Loiselle and Wones, 1979; Frost and Frost, 2011), (2) partial melting of quartzo-feldspathic crustal rocks (Creaser et al., 1991; Patiño Douce, 1997; Skjerlie and Johnston, 1992), (3) partial melting of …
In Argentina, Sn–W mineralization has been described from various Carboniferous granites in the Sierras Pampeanas orogen (Fig. 1) such as Sierra de Velasco (Báez, 2006), Sierra de Mazán (Fogliata and Báez, 2008) and Sierra de Fiambalá (Fogliata et al., 2008). Despite these numerous and detailed descriptions of Sn–W deposits and old ...
McCay and Younger, stablish that granites with a radiogenic heat production above 5.00 µW/m 3 are considered HHP granites, granites with values between 5.00 µW/m 3 and 3.00 µW/m 3 are considered MHP granites and the ones with a value below 3.00 µW/m 3 are considered LHP granites. According to this classification, five granitoids fall into ...

The Loma Pelada granites show characteristics of S-type magmatism (low CaO and MgO, and high SiO 2 and K 2 O contents) typical of granites segregated in the last stages of magmatic differentiation, or anatectic granites. They show an increasing peraluminosity due to garnet entrainment and they are related to the anatectic melts generated in the ...

The Characato suite (Achala batholith, Sierras Pampeanas, Argentina), consists of at least six granitic facies with affinities of F-rich moderately to strongly peraluminous A-type granites.The two more extensive facies (Facies 1 and 2) and a minor one (Facies 5) would represent at least three batches of magma generated by partial melting from the same source …
