  • Crystalline Aggregate Collection

    CRYSTAL HABITS AND AGGREGATES COLLECTION Many minerals form distinct crystal patterns as the crystals grow. Minerals may form isolated or distinct crystals, in radiating or parallel groups, or in a collection of crystals call aggregates. Aggregates of minerals sometimes are composed of scales or lamellae or of grains. Below is a list of terms geologists use to describe these crystal habits:
    ACICULAR -slender, needle like crystals MYGDALOIDAL A -rock with mineral filled cavaties
    BANDED -narrow bands of differing colors BLADED -elongated, flattened crystals
    BOTRYOIDAL -globular forms like a bunch of grapes CAPILLARY -hair like crystals
    COLLOFORM -spherical forms of radiating crystals COLUMNAR -column like crystal
    CONCENTRIC -spherical layers around a common center CONCRETION -minerals formed around a nucleus
    DENDRITIC -slender divergent branches DRUSY -a layer of small crystals on a surface
    FIBROUS -slender fiber aggregate of crystals FILIFORM -embedded threadlike crystals
    FOLIATED -easily separated into plates GEODE - a spherical hollow cavity lined by mineral(s)
    GLOBULAR -radiating crystals forming small spheres GRANULAR -composed of grain like crystals
    LAMELLAR -plate like crystals forming layers MAMMILLARY-round masses resembling mammae
    MASSIVE -a mineral w/o distinguishing features or form MICACEOUS -easily separated into thin sheets
    OOLITIC -aggregate of small spheres resembling fish eggs PISOLITIC -aggregate of spheres the size of peas
    RADIATED -radiating crystal groups RENIFORM -radiating crystals forming kidney shape
    RETICULATED -lattice like groups of crystals ROSETTE- a flowerlike crystal growth of minerals
    STALACTITIC-conical/cylindrical deposits of minerals STELLATED -radiating crystals forming circular groups
