Abstract
Mullalyup is a small village about 140 miles south from Perth and 33 miles by rail south-east from Bunbury. The main highway between Perth and Bridgetown passes through the village. The region is occupied by Basement rocks which appear to consist mainly of schist and gneiss. The regional strike is about north-west. The hill slopes and lower levels carry a heavy cover of soil and the hilltops are mostly covered with laterite and, in places, high-level gravels. These gravels are widely distributed in this region. The mica occurs, as usual, in pegmatite dykes, and five such deposits are shown on the attached plan. Some difficulty was experienced in locating these deposits owing to the thick undergrowth and hill terrain and it is probable that other pegmatites exist in the locality. Search was confined mainly to the slopes and it was considered that soil in the valleys and laterite on the hill tops would obscure outcrops of any pegmatite dykes, except at intermediate levels.
