n.〈地质学〉鲕粒岩
A small rounded accretionary mass,usually of calcium carbonate,larger and less regular than an oolite. 豆岩一种小的圆形沉积岩，常为碳酸钙，比鲕状岩大且不规则

Oolite lime sand packs naturally with 40% porosity because the particles are essentially spheroids. 自然堆积的灰质鲕粒砂具有40%25的孔隙度，因为其颗粒其本上都是球状的。

Natural gas mainly accumulated in oolite beach sedimentary facies of carbonate platform edge around Guangliang trough in Sichuan Basin. 天然气主要富集于广梁海槽两侧台地边缘鲕粒滩相区。
