Greisenization in Nigeria has affected three distinctive mineralogical
assemblages; perthitic granite, albitized variants, and microclinized variants. The
chemical ...

Geological Survey Professional Paper
Widespread vein mineralization and local greisenization are significantly
younger than the granitoid intrusive rocks, but the ages indicate a complex
plutonic and subsequent hydrothermal episode within a 5-m.y. interval near the
end of the ...

... have noted the occurrence of microlite in addition to columbite-tantalite in
greisenized granites and remark on the separation of niobium from tantalum and
the tantalum enrichment in the process of alteration, albitization, and
greisenization.

Giant Metallic Deposits: Future Sources of Industrial Metals
Hu Shouxi et al. (1984) pointed out that strong greisenization was a prerequisite
of a strong W mineralization to form. Simple veins at small deposits are quartz-
wolframite only, whereas at large deposits like Xihuashan (read below) the veins

Tardi and/or post-magmatic processes, such as albitization and greisenization
probably related to the skarn genesis, took place in the central part of the granitic
body, around 620 Ma ago, as supported by a Rb-Sr preliminary isochron.

Also, a strong correlation exists between the geometry of a given cupola and the
intensity of alteration: the most intense apical greisenization is associated with
small-diameter cupolas that have steeply dipping contacts. The paragenetic ...

Tectonics, Magmatism and Metallogeny of Mongolia
Zones of greisenization make up the later formations of the Modotin Massif.
Greisenization occurs within the coarse-grained granites of the main phase of
intrusion and also in the fine-grained and pegmatoid granites of the second
phase.
