山东大地构造相研究方法划分方案与基本特征

在系统收集山东已完成的1∶5万、1∶20万和1∶25万区域地质资料基础上，通过编制山东省1∶25万实际材料图和建造构造图、1∶50万大地构造相五要素工作底图和1∶50万大地构造相图，全面介绍了大地构造相的定义、研究内容、指导思想、基本原则与编图程序。采用大地构造相编图作为大陆动力学研究的主要方法，是揭示不同陆块之间相互作用、形成过程和演化历史、研究山东大陆块体离散、会聚、碰撞、造山的大陆动力学过程的主要载体和具体表达形式。进而对山东大地构造相进行了划分，共划出华北陆块区、秦祁昆造山系和中国东部陆缘弧盆系相系3大相系，鲁西陆块、渤海陆块、大别苏鲁结合带、威海弧盆系、胶辽岩浆弧和华北裂谷盆地6个大相以及20个相和59个亚相，明确了其鉴别标志。对陆块区、造山系和陆缘弧盆系相系以及大相、相的基本特征进行了描述；简要总结了大地构造相与成矿尤其是金矿的关系，探讨了不同矿床与大地构造相的成因联系。

Division Scheme and Basic Characteristics of Tectonic Facies Research Methods in Shandong Province

On the basis of collecting of regional geological data in Shandong province with the scale of 1∶50000,1∶200000 and a 1∶250000,through the preparation of actual materials and construction map in Shandong province with the scale of 1∶250000,five elements working base map of tectonic facies with the scale of 1∶500000,and tectonic facies map with the scale of 1∶500000,definition,research,guiding ideol-ogy,basic principles and map compilation process of tectonic facies have been introduced comprehensively. By using tectonic phase diagram as the primary method of continental dynamics research,interaction be-tween different continental blocks has been revealed,formation and evolution,Shandong discrete continen-tal blocks,convergence,collision,major orogenic processes of continental dynamics carrier and specific forms of expression.Furthermore,Shandong tectonic phase have been divided into three major phases, such as the North China Craton region,Qinqikun orogenic system and eastern China superposition orogeny rift system,5 large phases,such as Luxi land mass,Bohai Sea continental block,Dabie Sulu combina-tion belt,Jiaoliao magmatic arc,and Huabei rift basin,20 phases and 59 sub phases.Its identification sign has been determined.Basic characteristics of continental block,orogenic system,superimposed oro-genic rift system,large phases system and phases have been described.Relationship between tectonic phase and mineralization,in particular gold mineralization has been summarized,and the origin relation be-tween different deposits and different tectonic phases have been studied as well.
