糜棱岩

含眼球状碎斑的糜棱岩结构
Mylonite, Owl Mountains, Poland
Orthogneiss de Mervent mylonitisé.

具有糜棱结构的岩石称为糜棱岩。糜棱岩是一种变质岩,原岩经过强烈挤压,破碎后形成细粒,是一种动力变质岩石,粒度一般小于0.5毫米,但有时也含有少量比较粗的原岩碎屑,呈现为凸镜状定向排列的碎斑(porphyroclast)。

糜棱岩致密坚硬,主要由花岗岩、石英砂岩组成,伴生部分新生矿物,如绿泥石、绢云母、蛇纹石等,一般分布在断裂带的两侧。在中国的四川、云南断裂带有糜棱岩化带分布。

Mylonite is a fine-grained, compact rock produced by dynamic recrystallization of the constituent minerals resulting in a reduction of the grain size of the rock. It is classified as a metamorphic rock. Mylonites can have many different mineralogical compositions; it is a classification based on the textural appearance of the rock.
