Three types of endogranitic tin mineralisation have been recognised at Collingwood: steep siliceous sheeted veins, albitic veins and flat |
lying greisen. |
The majority of cassiterite is associated with en-echelon zones of siliceous, sheeted quartz-tourmaline and greisen veins. Alteration |
minerals include secondary quartz, muscovite (sericite), green biotite and tourmaline. |
