Silicalites, predominated by pelitic silicalite, occur in collisional zones and back-arc basins. In the collisional zones, they occur as rock sheet as an important part ofophiolitic mé lange, belonging to ophiolitic mélange type silicalite. In the back-arc or interarc basin, they occur as pelitic silicalite intercalation varying in thickness, characteristic of "silica merl",and belonging to abyssal back-arc basin type or carbonate type silicalite. In the magmatic arc, they occur as intercalation related to volcanic hydrotherm or volcalic exhalation, belonging to volcanic arc type silicalite.

在硅质岩方面：冈底斯构造带侏罗系硅质岩主要属泥质硅质岩，在各个碰撞结合带和弧后盆地中均有产出，主要的产出状态有：①在碰撞结合带中呈岩块产出，构成蛇绿混杂岩的重要组成部分，属蛇绿混杂岩型硅质岩；②在弧后或弧间盆地中呈厚度不等的泥质硅质岩夹层产出，常具"硅灰泥"特征，属弧后深水盆地型硅质岩；③呈夹层状产于弧火山岩系中，属火山热液或火山喷气型硅质岩。

Based on the geological background , ore?deposit and structural geology, the paper analyzed the geological character istics and metallogenic mechanism of the gold deposit and suggests that the deposit occurring in the limestone and metamorphic siliceous rocks in the third litholog ic unit of Devonian Tuokesalei formation is controlled by the Duolanasayi shear zone characteristic of secondary shear deformation, mineralizaion and multiphased vei n mineralization?.

笔者从地质背景、矿床地质，以及控矿构造分析了多拉纳萨依金矿矿床特征及其成矿机理；明确了矿床产于泥盆系托克萨雷组第三岩性段的灰岩－浅变质－硅质岩系，受控于多拉纳萨依韧性剪切带；控矿构造具有二次韧性剪切变形、矿化和多期次脉体矿化的特征，显示出构造活动的多期次性与复杂性，阐明了构造期次与矿化之间的关系。？
