| 摘 要： | 酸性、中酸性岩区火山构造洼地中火山－侵入岩浆活动广泛、强烈，因而在纵向上形成了一套巨厚的以酸性火山岩为主体，夹有火山喷沉积夹层的多旋回、多岩相组合的高钾钙碱性火山－侵入杂岩系，从定位的性质与深度可分为两个基本相带：以火山喷发为主的岩相划为地表管近地表相带；以次火山－浅成侵入为主的岩相划为近地表和火山根部相带。

| Abstract: | he volcanism and magmatic intrusion are widespread and extensive in the volcano-tectonic rent of the acid and intermediate acitity rock terrain. In the volcano-tectonic rent there is a series of thick multicyclic and mutifacies high-potassium cafe-alkaline volcanic and intrusive complexes which are composed of acidic volcanic rocks with the interbed of eruptive materials and can be divided into two basic lithofacies belts: surface and near-surface lithofacies belt (mainly as eruptive rocks) and near-surface and volcano root lithofacies belt (mainly assubvolcanic and hypabyssal intrusive rocks). In the volcano-tectonic rent there are different volcanic structural types and second fracture structures and there is a well-developed mineralization of Cu,Au,Ag,Pb and Zn. The volcanic hydrothermal deposits are mainly distributed over the surface and near-surface phase belt and the subvolcanic hydrothermal and magamatic hydrothermal deposits mainly over the near-surface and volcano-root phase belt. Therefore, the author put forward a lithofacies and structural metallogenic model of the volcano-tectonic rent. |
