TL;DR: In this paper, the authors studied the geodynamic evolution of skarn-type gold deposits in collisional orogenic belts, fault-controlled magmatic belts and reactivated collisional margins.

TL;DR: The Chang'an gold deposit, Yunnan province is one of five large gold deposits in the Ailaoshan gold belt that is the most important ore belt of the Sanjiang Tethyan metallogenic domain this article.

TL;DR: The major, minor and trace element chemistry of chlorite were evaluated as a tool for mineral exploration in the propylitic environment of porphyry ore deposits as discussed by the authors, and the results showed that a variety of elements, including K, Li, Mg, Ca, Sr, Ba, Ti, V, Mn, Co, Ni, Zn and Pb, are probably incorporated in the chlorite lattice and display systematic spatial variations relative to the porphyries center.

TL;DR: The Tuwu-Yandong porphyry Cu belt is located in the Eastern Tianshan mountains in the eastern Central Asian Orogenic Belt as mentioned in this paper, and the porphyries are characterized by high SiO 2 content but high MgO, Cr and Ni contents, similar to those of high-Mg andesites.

TL;DR: The Sawayaerdun gold deposit as mentioned in this paper is considered to be the largest Muruntau-type gold deposit in the Chinese Tianshan metallogenic belt, and the isotopic compositions of quartz and sulfides from the gold deposit show some variation but are generally comparable to those of other orogenic type gold deposits.
