Pegmatites are texturally complex igneous rocks marked by some combination of coarse but
variable crystal size, mineralogical zonation, prominent anisotropy of crystal orientations …

Metals such as Cu, Mo, Au, Sn, and W in porphyry and related epithermal mineral deposits
are derived predominantly from the associated magmas, via magmatic–hydrothermal fluids …

About 85% of all historically mined tin of about 27 million tonnes Sn is from a few tin ore
provinces within larger granite belts. These are, in decreasing importance, Southeast Asia …

Jiama is a giant skarn-porphyry deposit in southern Tibet, southwestern China. It is the
largest Cu (~ 7.4 Mt), second largest Au (~ 208 t), and fourth largest Mo (~ 0.62 Mt) skarn …

Granitoids are a major component of the continental crust. They play a pivotal role in its
evolution, either by adding new material (continental growth), or by reworking older …

在晚侏罗世时, 南岭地区发生了与花岗岩有关的钨锡铌钽大规模成矿作用. 依据花岗岩的岩石学,
地球化学及其矿化特征, 可将南岭地区含钨锡铌钽花岗岩划分为三个主要类型: 含钨花岗岩 …

The classification of granitic pegmatites was frequently attempted during the past century,
with variable degrees of success and applicability. Internal structure, paragenetic …

It has been widely accepted that magmas genetically linked to porphyry (-skarn) Cu (Mo)
deposits are commonly oxidized. Recently, using laser ablation-inductively coupled plasma …

Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …
