PEGMATITES TYPICALLY
OCCUR IN CLUSTERS
Overview of lithium pegmatite deposit geology
Pegmatites do not form in isolation:
they typically occur as members of
larger populations of cogenetic
bodies numbering tens to hundreds
and occupying a few tens of square
kilometres, or districts. At the district
scale, pegmatites typically display
mineralogical and geochemical
zonation that is broadly concentric
surrounding an exposed or inferred
granitic pluton.
Lithium pegmatite dykes
account for about one-fourth
of the world's lithium
production and are a distinct
class of mineral deposits.
Pegmatite dykes are late stage
igneous rocks characterized by
distinctive textures and
massive crystals that may
range up to several metres in
size.
Pegmatites tend to be intruded
into shallow crustal depths
along anisotropies such as
faults, fractures, foliation, and
bedding.
