Crystal aggregate
In mineralogy, crystal habit is the characteristic external shape of an individual crystal or aggregate of crystals. The habit of a crystal is dependent on its crystallographic form and growth conditions, which generally creates irregularities due to limited space in the crystallizing medium (commonly in rocks).

WebThere are basically two types: single crystal forms and aggregate forms. The single crystal terms are used to describe individual crystals and so terms like platy or prismatic are used. Aggregate terms are for minerals whose crystals come in groups of at times literally thousands of crystals and form a unique shape. Individual crystals in these ... WebAn Aggregate refers to a mass of well associated mineral matter, crystals, sediment, and various particulates that have grown together irregularly. Aggregates are grouped further based upon the shape of the aggregate such as granular, botryoidal, massive, fibrous, and radiating. Notable examples of aggregates include Dolomite, Auralite-23 ...
WebCrystal aggregates formed in shear at intermediate crystal fraction are hence observationally distinct from the Kīlauea Iki aggregates, most of which contain two to four individual crystals.
