What does fibroradiated mean in mineralogy ?

Fibroradiated : definition

This term refers to crystalline textures showing fibers radiating from a center. Each fiber corresponds either to a crystal or to a stack of small crystals of the same crystallographic orientation.

Pyrite (photo on the right), goethite, zeolites commonly offer this texture which can be found in concretions of organic origin (certain foraminifera tests) or in magmatic rocks (diorite spherulites for example).
