一、北西向构造概述位于新华夏系第二隆起带中之济阳拗陷南缘之邹平中生代陆相火山岩盆地,是一个受北西向断裂控制形成的断陷盆地,北西向断裂是组成该盆地构造格架的基础构造,它控制了盆地内的火山活动、岩浆侵入,使其盆地的火山岩系,侵入杂岩及相应的脉岩,矿化蚀变带在总体上是北西走向展布,串珠状分布的火山口也大致呈北西向排列;在地貌上,主要山脉亦呈北西——南东走向延伸。燕山运动晚期,由于沂沭断裂带强烈左行压扭活动、迁就和改造
I. Introduction to Northwest Structure The Zouping Mesozoic continental facies volcanic basin, located in the southern margin of the Jiyang depression in the second uplift of the Neo-Cathaysian System, is a fault basin formed by the NW-trending fault rupture. The NW-trending fault is composed of the basin Tectonic framework of the basic structure, which controls the volcanic activity within the basin, magma intrusion, so that the basin of volcanic rocks, intrusive complexes and the corresponding veins, mineralized alteration zone is generally northwest spread, beaded The craters distributed likewise are arranged in a northwest direction. On the landscape, the main mountain ranges also extend from northwest to south. Late Yanshan movement, the Yishu fault zone with a strong left twist and move, accommodation and transformation
