构造迁移论概述

INTRODUCTION TO TECTONIC MIGRAION THEORY

本文概述了构造迁移的涵义、与前人迁移概念的区别、构造迁移论的理论基础、研究内容、研究方法和在地质学中的应用。 构造迁移论是以构造运动为研究对象,它将不同期次的构造运动联系起来,建立有序的、动态的运动流的概念。目的在于查明运动轨迹,发掘迁移规律,划分迁移区,寻找全球基本迁移方向,探讨产生构造迁移的地球动力学和热力学机制,建立岩石圈点线面开合演化基本模式,应用迁移规律进行各种地质预测,特别是找矿区预测,开拓地质研究新领域,为地球科学增添新内容。

This paper outlines the meaning of tectonic migration theory and its distinction from the concept of tectoic migration by our predecessors, and briefly discussed the theoretical basis of the tectonic migration theory, and its research content, method and application in geology.The theory of tectonic migration takes tectonization as its object of investigation and establishes a dynamic and regular ordinal concept for the kinematic-hydrodynamics with relation to the tectonization of different tectonic episodes. The purpose of this theory lies in finding the locus of tectonization, exploring the law of tectonic migration, dividing the domains of tectonic migration, seeking the basic directions of tectonic migration on the global scale, inquiring the mechanism of geodynamics and thermodynamics for the tectonic migration, building the basis point-line-plane evolution model for the lithospheric splitting and closing, as applying this theory in various geological prognoses, especially in prospecting prognoses, and opening up a new domain and contents for geological sciences.The concept of tectonic migration was advanced by Jiang Chunfa (Geo-tectonic fundamental feature of China, 1960), was briefly mentioned in 1962 (reference 1), and was further expounded in 1980(reference 2). The concept of tectonic migration was gradually systematized with uninterrupted accumulation of the material, and successively developed and became the embryo of the tectonic migration theory.The view point of tectonic migration was publicised in some geological surveys, colleges, geological units and study classes, attracting geologists interest. Some geologists, including authors of 《RIGIONAL GEOLOGY》of some provinces (regions), quoted the theory to discuss the problems of tectonic-migration in some regions and some subjects (references 3-16). This paper only gives an outline of the tectonic migration theory in order to make public and academic exchanges.
