Jun 29, 2017 (Therese Pettigrew) - The biotite-quartz-feldspar schist is a dark-coloured, grey rock having a banded appearance due to compositional variations in the original sediments. While the major portion of sequence is granoblastic in texture, porphyroblastic rocks are also present containing porphyroblasts of one or more of garnet, staurolite and cordierite. These minerals are more resistant to erosian and hence stand up in marked relief on outcrop surfaces. The medium- to coarse-grained granitic rocks are pale grey or pale pink in colour generally massive in nature and consist primarily of feldspar, quartz and mica. The pegmatites are closely associated with the granite and are of two types. The potentially economic pegmatites consist of feldspar, quartz, muscovite and most importantly spodumene, while the second type are the more normal granitic pegmatites (AFRI 42E05SW8331).
