Extract

The country in the vicinity of Toodyay, which is situated approximately 60 miles north-east from Perth, is occupied by a series of Archaeozoic metasedimentary and igneous rocks (Text-fig. 1). The metasediments include interbedded sillimanite-and andalusite-mica-schists, extremely pure quartzites and occasional narrow bands of calc-silicate rocks. The igneous rocks occur as (1) narrow bands of schistose plagioclase-amphibolite (interbedded with the metasediments) which appear to have been originally sills or flows of tholeiitic character; (2) wider bands of fluxion microcline- (and oligoclase-) granite-gneisses occurring as concordant thick sill-like bodies in the metasedimentary strata; (3) Quartz-dolerite dykes, intrusive into all the above-mentioned rocks. Some of these rocks, which are developed in the Jimperding valley (about 6 miles southwest from Toodyay), have been previously described (Prider, 1934).
