摘要
本文简要介绍了产于华北板块与扬子板块碰撞带范围内的苏北-胶南构造混杂岩带的地质构造背景,并系统地研究滑移介质、中-浅源和深源构造块的基本特征。在深源构造岩块的研究基础上建立了壳幔过渡带至上地幔段的岩性地层柱,对上地幔可能存在的地质作用类型进行了探讨。
This paper briefly describes the geologic-tectonic setting of the tectonic melange in Northern Jiangshu-Southern Shandong region. This tectonic melange occures in the collision zone between North China and Yangzi Plates. The principal features of the sliding medium, shallow-middle- and deep-seated tectonic blocks. have been systematically studied in this paper as well. Based on the study of deep-seated tectonic blocks, a litho-logic column from upper mantle to crust-mantle transition zone bas been established, and the possible geologic process in upper mantle has been discussed.
