拆离构造动力学与地洼理论

DYNAMICS OF DENUDATION TECTONICS AND DIWA TECTONICS THEORY

拆离构造是当前地学中的研究热点,对其研究具有重要的理论与经济意义。在20世纪90年代初,笔者应《铀矿地质》编辑部之约,以“拆离构造理论与找矿实践”命题分八个方面在“铀矿地质”期刊断续刊登,其内容涉及:(1)拆离构造在我国研究的新进展;(2)拆离构造概念的演化与地球圈层;(3)拆离构造基本含义与相关构造术语;(4)拆离构造形成的动力学讨论;(5)拆离构造的厘定和鉴别;(6)拆离构造的研究方法;(7)拆离构造控矿理论与找矿;(8)拆离构造研究展望。本文仅就拆离构造的动力学机制研究和地洼理论在拆离构造动力学研究中的应用作简要论叙,并以此草文敬献陈国达院士九十华诞以兹纪念。

The denudation tectonics is,at prasent,a focus of the study in geoscience.A study on the de-nudation tectonics is of not only gre at theoretical significance,but also more economic importance.For the studying and applying the theory of d enudational tectonics and on the invitation of the Editorial Department of'Uranium Geology'in the 1990s,the paper'Theory of denudational tectonics an d practice in prospecting',had been writtern and was divided int o several issues with the following c ontents accordingly:(1)New pro-gress in the research on denudational tectonics in China;(2)The evolution of denudational tecto nics'con-cept and layer zoning of the Earth;(3)The fundamental implication of the d enudational tectonics and rel-evant tectonic terminology;(4)Discussion on dynamics of the formation of denudational tectonics;(5)De-finition and discrimination of denudational tectonics;(6)Research method of denudational tectonics;(7)Ore-controlling theory of denudational tectonics and prospecting;(8)Outlook on the research of denudatio nal tectonics.This paper briefly discu sses dynamic study of denudational t ectonics and application of diwa tec-tonics theory on dynamics of denudational tectonics.
