茶叶山辉长岩杂岩体分布于鲁西台背斜邹平火山洼地的西南缘,属于西窝陀-十九郎庄-茶叶山-大临池弧形辉长岩杂岩体的南段,为燕山期岩浆活动产物。该杂岩体由两期四次侵入而成。各期次岩体的类别、产状、岩相及分布情况如表1所示,其中以辉长岩期第一次侵入的苏长辉长岩体分布最广。兹将该岩体的岩石学特征及在该岩体中找寻铜镍矿床的前景介绍如下:
Tea Hill gabbro complexes are distributed in the southwestern margin of the Lupineta anticline Zouping volcanic depression and belong to the southern segment of the Xiwotuo-Shijulangzhuang-Tea Hill-Dailingchi gabbro complex. Period magmatic activity product. The complex consists of two intrusion from four times. The types, occurrences, lithofacies and distribution of rock mass in each phase are shown in Table 1, of which the most widely intruded Permian gabbro body is the first intrusive in the gabbro period. The petrological characteristics of this rock mass and the prospect of finding Cu-Ni deposits in this rock mass are hereby introduced as follows:
