辽宁省地槽区的志留系—奥陶系分布于辽宁省北部,奥陶系称下二台群,由下向上分为盘岭组、黄顶子组、烧锅屯组;分布于辽宁省西部的奥陶系称明安山群。志留系下统为巴林桥组,中统为晒勿苏组。下二台群是一套变质的火山岩系夹正常海相沉积层,火山岩的岩石化学成分及岩石结构与甘肃白银厂早古生代火山岩相似。在火山岩系中已发现有多处铜、金矿点,显然辽宁省北部下二台群是寻找铜、金、银的理想地区。
The Silurian-Ordovician digesters in Liaoning Province are distributed in the northern part of Liaoning Province. The Ordovician group is called Erzitun Formation, which is divided into Panling Formation, Huangdingzi Formation and Xuguo Tuen Formation from the bottom up. It is located in the western part of Liaoning Province Ordovician Ming Ming Anshan group. Silurian system for the Bahrain Bridge Group, the system for the sun Matsu group. The Lower Second Group is a set of metamorphic volcanic rocks with normal marine sediments. The petrochemical composition and rock structure of volcanic rocks are similar to that of the Early Paleozoic volcanic rocks of the Baiyin Plant in Gansu Province. In the volcanic rock series have been found in a number of copper, gold point, apparently Liaoning Province, the next two groups is looking for copper, gold, silver ideal area.
