角砾岩

Brecha de basalto; la masa verde es de epidota.
Brecha sedimentaria.
Megabreccia (left) at Titus Canyon Narrows, Death Valley National Park, California

角砾岩和砾岩一样,也是一种碎屑岩,由从母岩上破碎下来的,颗粒直径大于2毫米的碎屑,经过搬运、沉积、压实、胶结而形成的岩石,砾石的平均直径如果在1-10毫米,为细砾,10-100毫米称为粗砾,大于100毫米为巨砾。其胶结物中常含有矿物,角砾岩也可以做为建筑材料。

角砾岩比较粗糙,可以见到明显的砾石,如果胶结成岩石的砾石超过50%是圆形的为砾岩,超过50%为具有棱角的,则称为角砾岩。

一个角砾岩可能有许多种不同的起源,由命名的类型所显示,包括沉积角砾岩,构造角砾岩,火成角砾岩,撞击角砾岩,和热液角砾岩。

A breccia may have a variety of different origins, as indicated by the named types including sedimentary breccia, tectonic breccia, igneous breccia, impact breccia, and hydrothermal breccia.
