- Their original rocks are volcanic rocks, epicontinental clastic sedimentary rocks, and ophiolite of volcanic and island arc tholeiitic series or calcium alkali series. 其原岩岩石类型有火山岩,陆缘碎屑沉积岩,火山、岛弧拉斑系列或钙碱系列火山岩、蛇绿岩等。
- The massive sulfides related to felsic volcanic rocks in the back-arc and island arc environments have higher content of gold. 通常形成于弧后或岛弧环境下的同长英质火山岩有关的块状硫化物中的金含量较高。
- Under the tectonic backgrounds of island arc belt, fore-arc trench belt, back-arc basin, and epicontinental active belt of Late Paleozoic, it has different volcanic rock characteristics. 在晚古生代岛弧带、弧前海沟带、弧后盆地或陆缘活动带等构造环境下发育有不同的火山岩组合。
- Therefore, the tectonic environment of the volcanic rocks in the Luxi area occurred in the late stage development of island arc system near to the side of continent with a thickening crust condition. 因此盆地腹部陆西地区火山岩的喷发环境应该是在岛弧发展后期,属于岛弧近大陆一侧、在地壳增厚的环境下喷发。
