| 摘 要： | 山东徂徕山区珂洛山、刘家山一带岩浆杂岩分布广泛,按岩相学、地球化学等特征可划分为闪长质岩组和花岗质岩组两大系列。闪长质岩组中的细粒闪长岩与泰山地区的普照寺型闪长岩相当,中粗粒闪长岩与中天门花岗闪长岩一致,二者可能产生于长期亏损地慢源.花岗质岩组中的黑云二长花岗岩测得锆石U—Pb一致线年龄为2440±_(22)~(23)Ma,其岩石学和地球化学特征均与泰山地区的傲徕山花岗岩相当,系由变质岩地壳熔融而来的深成流体形成.徂徕山杂岩体和泰山杂岩体区域片麻理走向一致,共同组成鲁西绿岩——花岗岩地体。

| Abstract: | According to the field investigation, petrographic examination, petrochemical and geochemical analyses, and a few isotopic age determinations, the features of the Zulaishan complex are very similar to those of the Taishan Complex. The Zulaislian Complex, like the Taishan Complex, can be subdivided into diorite and granite groups which have intruded into the basement of the Taishan Group, The diorite group is composed of finegrained one and medium-coarse grained one; the former corresponds to Puzhaosi diorit... |
