The authors classified the NE-,NW-,ENE-and ENE-striking and SW-,NE-,ESE-and WNW-dipping into four sets of conjugate joints,belonging to the regional NW-and N-S-trending structures respectively.
运用野外观察分析和构造解析方法,遵循共轭节理配套分期原则对大渡河金川坝区发育的节理构造进行逐步分析研究,可将该区发育的NE向、NEE向,NEE向、SW向,倾向SW、倾向NE,倾向SEE和倾向NWW的节理构成4套共轭节理,分别属于区域北西向和南北向构造的组成。
The principle of determination of conjugate joints and the method of structural analysis were applied to the study of secondary joints developed in the Xiluodu area.
运用构造解析方法 ,遵循共轭节理配套原则对溪洛渡地区发育的次生节理构造进行逐步分析 ,将该区发育的北东向和北西向节理、近南北向和近东西向节理、倾向南东和北西的两组北东南西向剖面节理、北东东向和北北东向节理以及倾向北东和南西的两组北西南东向剖面节理组成 5套共轭节理 ,分属南北向、北东向和北西向 3个构造期次。
The study of conjugate joints is a reliable method used for discussing the structural stress field,which conduces to the understanding of the tectonic activity mechanism and the development history of tectonism.
共轭节理研究是用来探讨构造应力场的一种可靠方法,它有助于了解构造活动机制和构造运动的发展史,对于矿产预测、水文工程地质及地震预报均具有重大意义,且对加深图幅地质构造研究、成岩成矿分析和提高图幅质量起重要作用。
