| 摘 要： | The Emei pyrophyllite ore district is localized in the middle part of eastern Fujian volcanic eruptive belt, within the Mesozoic fault mobile zone along the coast region of Fujian and Zhejiang. Upper Jurassic (J3n) Nan Yan Formation, which is composed mainly of rhyolitic erystalclastic tuff-lava, rhyolite and rhyolitic crystal tuff, is widely distributed throughout this region. Pyrophyllite and alumstone ore bodies occur principally in the rhyolitic crystal tuff and volcanic breccia-bearing tuff in the IV litbofaeics of the Nan Yan Formation. As a result of hydrotbermal metasomatism closely related to volcanic activities, pyrophyllitization, silicifieation and alunitization, empholitization, pyritization, and etc. are extensively developed, causing a systematic migration, enrichment and resetting of the constituents in the tuffs.
