We distinguish hetween liquid-magmatic, pegmatitic, pneumatolytic and
hydrothermal deposits. Liquid-magmatic deposits Liquid-magmanc deposits
occur in the initial phase of cooling at tempemtures hetween 1 200 and b00'C,

LODE DEPOSITS Lode tin deposits can be classified into six distinct types,
following the classification of Ahlfeld (1958) : (1) pegmatite deposits, (2)
pneumatolytic- hydrothermal deposits, (3) subvolcanic or tin-silver deposits, (4)

Geology and ore deposits near Lake City, Colorado
The older term "pneumatolytic" was formerly commonly applied to ores supposed
to have this derivation, but was used in a much narrower sense, being applied
only to deposits like the Cornwall tin veins, where minerals rich in boron, fluorine,

Introduction to Mineralogy and Petrology
Tourmaline (Fig. 1.18) is very abundant second- ary mineral, especially in acidic
intrusives (granites), pegmatites and rocks affected by pneumatolytic processes.
Tourmalines are typical pneumatolytic minerals that crystallize in pneumatolytic ...

Mineralogical and Structural Evolution of the Metamorphic Rocks
Pneumatolytic scapolites are generally of more sodic composition, and
correspondingly richer in chlorine, than scapolites formed by normal
metamorphism. They occur not only in calcareous rocks, where their presence
implies addition of ...
