摘要
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 Formation, 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. 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.
