| Research on Metallogenic Geological Background of Emerald in Taxkorgan, Xinjiang |
| Based on research on regional metallogenic background of emerald (beryl) in Xinjiang, the authors made a systematic study, test and analysis of petrologic geochemical characteristics of volcanic rocks in strata of Wenquangou Fomration, the strata that produced emerald deposits, which included its petrologic chemical characteristics, trace elements and REE, and determined that its tectonic environment was an active epicontinental subduction zone, i.e., a back-arc pull-apart environment formed after the formation of island arc resulting from the subduction of the ocean crust towards the continental crust. It was generally an active epicontinental environment on the side of the continent, and somewhat had characteristics of the transition from the island arc to the continent. |
