摘要
在河南西峡县洋淇沟岩体边部识别出大量以超镁铁质—镁铁质为主的多种类型糜棱岩,它们是康棱岩化橄榄岩、橄榄岩质糜棱岩、斜长角闪质糜棱岩等。这类岩石是岩体沿板块碰撞带构造侵位时强应变条件下的产物。
On the edge of the ultramafic rock mass in Yangqigou in Xixia county, Henan province, there occurs a varied type of mylonites giving priority to ultramafic-mafic mylonites including mylonitized peridotite, peridotite-mylonite, plagioamphibolite-mylonite, etc.,which were formed under the condition of strong strain as the rock mass emplaced tectonically along the plates collision belt.
