Pseudomorphism of alkali feldspar to biotite from the alkaline nana complex granite in Cameroon

Discover Geoscience
Alkaline complexes all over the world generally are enriched in high–field strength elements and rare earth elements. This enrichment can be accounted for by magmatic processes, but, many of these complexes display evidence of hydrothermal alteration. In

Brecciation and Associated Mobile Submagmatic Emplacement of Alkali Feldspar Rich Rocks At Lake La Cloche, Harrow Twp, Ontario [PDF]

, 1971
Tensile fracturing and expansion possible relating to tectonic activity and faulting have in part controlled the emplacement of alkali feldspar rich rocks in Heronian sediments at Lake La Cloche, south of Massey, Ontario. The rocks include 1. albitite -
