放射虫岩
放射虫岩是硅质岩的一种，硬度较高、粒度较细、与燧石相似，主要由放射虫死亡后的残骸构成。放射虫岩这一名词也应用于已固结的放射虫软泥。未固结的放射虫岩被称为放射虫土。放射虫燧石是层理发育，微晶的放射虫岩，硅质胶结或硅质基质的一种放射虫岩。

Radiolarite 放射虫岩
Radiolarite is a siliceous, comparatively hard, fine-grained, chert-like, and homogeneous sedimentary rock that is composed predominantly of the microscopic remains of radiolarians. This term is also used for indurated radiolarian oozes and sometimes as a synonym of radiolarian earth. However, radiolarian earth is typically regarded by Earth scientists to be the unconsolidated equivalent of a radiolarite. A radiolarian chert is well-bedded, microcrystalline radiolarite that has a well-developed siliceous cement or groundmass.
