Buchan Bay Li, Cs, Rb prospect

     Basic Li Grassroot Facts.

Breaks and Tindle, 1997 :

- Fertile granites differ from barren (common) granites in their geochemistry, mineralogy, and texture. Fertile granites tend to be large plutons or batholiths, typically greater than 10 km2 in outcrop area .

Selway, Breaks & Tindle, 2004 :

-They are silicic (quartz rich) and peraluminous (A/CNK > 1.0), resulting in crystallization of Al-rich minerals such as muscovite, garnet, and tourmaline.  

- The presence of muscovite in barren granites tends to be silver colored and medium grained, whereas muscovite in fertile granites and pegmatites tends to be green (but may also be brown, silver, and rarely pink) and coarse grained (>2 cm across).

-The presence of garnet in a granite indicates that the granite is peraluminous and fertile, because barren granites do not contain garnet.

-The presence of pink, green, or blue Li-rich tourmaline indicates that the pegmatite has economic potential for Li, Cs-Ta, although not all Ta-mineralized pegmatites contain tourmaline. 

-The presence of blue or green Mn-rich fluorapatite indicates that the pegmatite has economic potential for Li-Cs, Ta, although not very many Ta-mineralized pegmatites contain Mn-rich fluorapatite.

-The presence of beryl indicates that the granite is fertile and peraluminous, because barren granites do not contain beryl.
