Geology

Alteration processes:

Some lamprophere dikes have tactite borders but these may not be related to mineralization. The origin of dolomite and dolomite breccia is also not clear here. Mass balance calculations show significant SiO2, Al2O3, alkali, and fluorine enrichment with mineralization (Sainsbury, 1968, p. 1567).
