“眼状构造”及其控矿模式

与变质岩微观的眼球状构造相对应．在花岗岩发育区，由于强烈的张剪切作用．形成一种类似于眼球状构造的大型花岗岩眠状构造．它是卫星照片或航空照片上经常出现的构造形式，这种宏观甚至起宏观的眼状构造基地壳上一种普遍的构造类型、由于它受到张剪性应变的严格控制．形成特定的眼角区、眼睑和眼圈．矿体的形成、定位和分布常常受到眼状构造的控制，因此．可将它列为一种控矿构造类型。

EYE STRUCTURE" AND ITS ORECONTROLLING MODEL

Curresponding to micruscupic eye structures in metamurphic rocks, huge eye structures,due to strong tensivnal shearing, are common appearde in well-developed granite areas, shown on satellite or aerial phutugraphs. Those macroscopic of supermacroscopic eye structures are typical ones in the earth crust. Due to strick cuntrolling by tensional shearing stresses, eyeCanthi, eye lids and sock ets were formed and these features have becume ind ications for ore-forming, ore locatins and ore distribtltions. So eye structure can be regarded as one of typical ore-controlling structures.
