| 摘 要： | 石柱子杂岩体分布在辽东宽甸地区东部,大地构造位于中朝准地台胶辽台拱与太子河凹陷接触带附近,锆石U-Pb法同位素年龄为129Ma,侵位时代为中生代早白垩世。按照侵入岩岩石单位的划分原则,由早期到晚期划分为大砬子沟石英闪长岩、振江花岗闪长岩、赤榆顶子二长花岗岩。成因类型为I型花岗岩类,为幔源岩浆成因的钙碱性岩石系列侵入岩,岩浆由中性向酸性演化,演化趋势明显,构成了完整的演化序列。成岩环境为大陆边缘活动带型钙碱性岩石系列侵入岩。石柱子杂岩体周围的金、铜、钼、铅、锌、铁矿床及矿(化)点的形成是由石柱子杂岩体提供矿质源及热源。

| Abstract: | Shizhuzi complex,which is situated in the contact zone between Jiao-Liao platform-uplift and platform-subsidence,is distributed at east area of Kuandian.Its isotope dating of zircon U-Pb is 129Ma represented its intrusive age of Cretaceous in Mesozoic era.According to petrology and age,the Shizhuzi complex can be grouped into Dalazigou quartz diorite,Zhenjiang granodiorite,Chiyudingzi adamellite.All of this cell is belonged to the calc-alkaline series and I-type granite.The evolution trend of magma is obviously completed evolution series.The diagenesis environment of tectonics is in mobile belt of continent edge. |
