Sanjiang Tethyan metallogenesis in S.W. China: Tectonic setting, metallogenic epochs and deposit types

Tectonically, the Sanjiang Tethyan Metallogenic Domain (STMD) is located within the eastern Himalayan–Tibetan Orogen in the Sanjiang Tethys, southwestern China. Although this metallogenic domain was initiated in the Early Palaeozoic, extensive metallogenesis occurred in the Late Palaeozoic, Late Triassic and Himalayan (Tertiary) epochs. Corresponding tectonic settings and environments in the domain are: an arc-basin system related to the subduction of the Palaeo-Tethyan oceanic slabs; a post-collision crustal extension setting caused by the lithospheric delamination or slab breakoff underneath the Sanjiang Tethys during the Late Triassic; large-scale strike-slip faulting and thrusting systems due to the Indo-Asian continent collision since the Palaeocene. In this metallogenic domain important gold, copper, base metals, rare metals and tin ore belts, incorporating a large number of giant deposits, were developed. The main types of deposits include: (1) porphyry copper deposits, controlled by a large-scale strike-slip fault system, (2) VHMS deposits, mainly occurring in intra-arc rift basins and post-collision crustal extensional basins, (3) shear-zone type gold deposits in the ophiolitic mélange zone along the thrusting–shearing system, (4) hydrothermal silver-polymetallic deposits in the Triassic intra-continental rift basins and Tertiary strike-slip pull-apart basins, and (5) Himalayan granite-related greisen-type tin and rare-metallic deposits. Within the metallogenic epochs of the Late Palaeozoic to Cenozoic, the styles and types of the ore deposits changed from VHMS types in the Late Palaeozoic through exhalative-sedimentary type deposits in the Late Triassic, to porphyry-type copper deposits, shear-zone type gold deposits, hydrothermal vein-type silver-polymetallic deposits, greisen-type tin and rare-metal deposits in the Cenozoic. Correspondingly, ore-forming metals also changed from a Pb–Zn–Cu–Ag association through Ag–Cu–Pb–Zn, Fe–Ag–Pb and Ag–Au–Hg associations, to Ag–Cu–Pb–Zn, Cu–Mo, Au, Sn, and Li–Rb–Cs–Nb–Zr–Hf–Y–Ce–Sc associations.

民乐火山岩-次火山岩型铜矿

民乐铜矿产于中三叠统钙碱性、碱性系列火山碎屑岩、熔岩、次火山岩(英安斑岩)中。矿床形成与陆相火山活动及其后的火山热液、英安斑岩体侵入有关,明显受火山岩岩性、岩相、层位及构造控制。成因上与火山喷发、英安斑岩体侵入作用有关,具有斑岩铜矿的一些特征。矿床受后期火山热液,次生富集叠加改造明显。     

Exhumation and Preservation of the Jinchuan Ni-Cu-PGE Deposit under the East Longshou Mountain Thermal Evolution,Revealed by Apatite Fission Track Thermochronology

Uplift and exhumation are important factors affecting the preservation of deposits. The anatomy of uplift-cooling evolution and exhumation in the East Longshou Mountain is of significant research value in understanding changes in the Jinchuan Ni-Cu-PGE deposit since its formation. This study uses apatite fission track(AFT) thermochronology to reconstruct the thermal history of the East Longshou Mountain, including the Jinchuan mine, revealing the uplift and exhumation history of the East Longsho...
