Argentina, granites in China, and pegmatites in Australia, China, and Zimbabwe. An important aspect of the lithium R areelement granitic pegmatites are well recognized for the diversity and concentrations of metal ores that they host. The supply of some of these elements is of concern, and the European Commission recently designated metals such as tantalum and niobium as "critical materials

Three granitoid types are recognised in the Famatinian magmatic belt of NW Argentina, based on lithology and new geochemical data: (a) a minor trondhjemitetonalitegranodiorite (TTG) group, (b) a metaluminous Itype gabbromonzogranite suite, and (c) Stype granites. The latter occur as small cordieritic intrusions associated with Itype granodiorites and as abundant cordieritebearing facies

· Two weathering profiles evolved on peneplainrelated granites in Sierra Norte, Córdoba province, were examined. Several weathering levels, of no more than 2 m thickness, were studied in these profiles. They had developed from similar parent rock, which had been exposed to hydrothermal processes of varying intensity. Fracturing is the most notable feature produced by weathering; iron

The centraleastern part of the Sierra de Velasco (Sierras Pampeanas, NW Argentina) is formed by the large Huaco (40 × 30 km) and Sanagasta (25 × 15 km) granite massifs and the small La Chinchilla stock (2 × 2 km). The larger granites intrude into Ordovician metagranitoids and crosscut Devonian (?) mylonitic shear zones, whereas the small stock sharply intrudes into the Huaco granite.
