globular texture
Quick Summary
In geology, a globular texture describes mineral grains that radiate outwards to form small spherical or hemispherical groups. This is a type of crystal aggregation, where individual crystals grow together.1
The texture of an igneous rock, defined by the size, shape, and arrangement of its mineral grains and any glass present, provides clues about the conditions under which the rock formed. While specific textures like ophitic or poikilitic describe particular intergrowths, globular texture refers to a distinct radiating pattern of crystal growth.21
