摘要
在概述脆－韧性变形时空转换的过程、成生机制、影响因素和时空结构基础上，着重论述了变形转换过程中岩石构造破裂的形成机理、水动力学条件，以及构造破裂与流体流动、矿质聚集间关系，总结了与变形转换有关的两类成因不同的剪切带型金矿床的产出特征和形成条件。
After summarized the time/space structure,affecting factors and evolutionprocess of the brittle-ductile transition,this paper predomintly discusses the developingmechanism and hydrodynamic condition for the rock fracturing,researches the relationshipamong the rock fracturing, fluid flow and accumulation of ore-forming element, andfinally presents the geological characteristics and their origin for two kinds of ore deposits,i.e.mesothermal and epithermal hydrothermal An deposits,which related with transitionsegment of shear zone in different way.
