鲁西地区中生代沂南超单元基本特征

BASIC CHARACTERISTICS OF MESOZOIC YINAN SUPERUNIT IN WEST OF SHANDONG

摘要:

“七五”以来，鲁西地区开展的１∶５万和１∶２０万区调工作，对中生代侵入岩的研究逐步深入，建立了济南、铜石、埠村、沂南等超单元。本文对重新厘定的沂南超单元的基本特征及所属单元典型侵入体（命名地点）的特征作了初步介绍，并对这套中基性杂岩体的形成时代、就位机制、岩浆演化及与铜、铁、金矿化的关系进行了探讨。

Abstract:

Since the seventh“fiveyearplan”,the regional geological survey with the scale of 1∶50,000 and 1∶200,000 in west of Shandong has been carried out, and the Mesozoic intrusives have been further studied, where Jinan, Tongshi,Bucun and Yinan superunits established. In this paper, the basic characteristics of Yinan superunit and its typical intrusives(namegiven location)have been primarily introduced. Their forming age, emplacement mechanism, magmatic evolution and the correlation of copper, iron and gold de...
