fibrous texture
Quick Summary
The term "fibrous" describes a texture resembling a mass of strings. In mineralogy, a fibrous texture refers to an aggregate of slender, parallel, or radiating fibers. This texture is often observed in minerals like gypsum (satin spar) and chrysotile asbestos.123
Minerals form under various geological conditions, including igneous, sedimentary, metamorphic, and hydrothermal processes. The texture of an igneous rock, defined by the size, shape, and arrangement of its mineral grains, provides insights into its formation. While "fibrous" describes a specific texture, it's one of many ways mineral aggregates can be characterized.4562
