Autor: Reimar Seltmann, Jens C.Ø. Andersen, Chunji Xue, Xiaobo Zhao, Ling Xing, Xinjie Cui, Weice Zhao, Alla Dolgopolova

Publikováno v: Geological Society, London, Special Publications. 516:155-176

The western Tianshan Gold Belt hosts numerous giant and large gold deposits that have been formed during the late Paleozoic amalgamation of the Tianshan orogen. However, little is known about their exhumation histories during the Mesozoic to Cenozoic

Cooling and exhumation of the Late Paleozoic Tulasu epithermal gold system, Western Tianshan, NW China: implications for preservation of Pre-Mesozoic epithermal deposits

Autor: Xiaobo Zhao, Weice Zhao, David T. A. Symons, Reimar Seltmann, Chunji Xue, Yong Zhang, Alla Dolgopolova

Publikováno v: Journal of the Geological Society. 178

Epithermal gold deposits are rarely well preserved in pre-Mesozoic terranes because of their low-temperature mineralization at shallow crust levels, and they are easily destroyed by subsequent erosion or depleted by tectonic events. However, several
