韧性剪切带型金矿床作为重要金矿床类型之一,对其进行深入研究具有重要的理论和实际意义。以辽宁排山楼金矿床和广东河台金矿床2个典型韧性剪切带型金矿床为例,对韧性剪切带型金矿床地质特征进行概括和总结。韧性剪切带型金矿床与其赋存的韧性剪切带往往具有形成时间上的滞后效应,矿体严格受韧性剪切带控制,但多分布在韧性剪切带的后期脆性断裂中。剥蚀程度低、长期演化的造山带环境是寻找韧性剪切带型金矿床的战略方向。
韌性剪切帶型金礦床作為重要金礦床類型之一,對其進行深入研究具有重要的理論和實際意義。以遼寧排山樓金礦床和廣東河檯金礦床2箇典型韌性剪切帶型金礦床為例,對韌性剪切帶型金礦床地質特徵進行概括和總結。韌性剪切帶型金礦床與其賦存的韌性剪切帶往往具有形成時間上的滯後效應,礦體嚴格受韌性剪切帶控製,但多分佈在韌性剪切帶的後期脆性斷裂中。剝蝕程度低、長期縯化的造山帶環境是尋找韌性剪切帶型金礦床的戰略方嚮。

The ductile shear zone type of gold deposits as one of the important gold deposits is worth further study for this type of gold deposits and has important theoretical and practical significances .In this paper,taking Paishanlou gold deposit(Liaoning Province) and Hetai gold deposit(Guangdong Province),two typical ductile shear zone types of gold deposits,for example, summary and conclusion of geological characteristics of the ductile shear zone types of gold deposits have been made.The ductile shear zone type of gold deposit tends to have lagged effects on the formation time compared with the ductile shear zones it occurs in .The ore bodies are strictly controlled by ductile shear zones ,but are always located in late brittle fracture of the ductile shear zones .The paper pointed out that the orogenic belt environ-ment with low denudation and long-term evolution is the strategic direction of looking for the ductile shear zone type of gold deposits.
