柳河地区变质核杂岩顶部发育的大型韧性剪切带内金矿点星罗棋布,可开发利用的金矿产较少,文中探讨了金矿产形成作用与韧性剪切带和拆离断层的关系,认为金矿产在深部形成后能够抬升至浅表层次的重要条件是构造抬升,但是区域构造活动进入稳定期后,隐伏的矿产已经不再具备构造抬升条件,所以该区深部隐伏金矿产的寻找是重要的找矿方向。
柳河地區變質覈雜巖頂部髮育的大型韌性剪切帶內金礦點星囉棋佈,可開髮利用的金礦產較少,文中探討瞭金礦產形成作用與韌性剪切帶和拆離斷層的關繫,認為金礦產在深部形成後能夠抬升至淺錶層次的重要條件是構造抬升,但是區域構造活動進入穩定期後,隱伏的礦產已經不再具備構造抬升條件,所以該區深部隱伏金礦產的尋找是重要的找礦方嚮。

Many gold ore spots are distributed in large ductile shear zone,which developed at the top of the metamorphic core complex in Liuhe area,in which less developed and available.In this paper,discussed the relationship between gold deposits formation and the ductility shear zone and the detachment fault,it is considered that constructed uplift is the important condition that gold deposits in deep formation can be lifted to the superficial layers,after regional tectonic activities entered stability period,concealed orebody was no longer with tectonic uplift conditions,so the searching of deep concealed gold deposits is important prospecting direction.
