Geology and mineralazation in the southern Lachlan Fold Belt: Copper mineralisation at The Basin Creek No. 1 prospect, tumut, new south wales

Abstract

The Basin Creek No. 1 prospect is located in the Snubba Range 14 km south of Tumut. The host rocks are phyllites and intermediate metavolcanics of the (?) Middle Silurian Blowering Beds. Locally, these are about 1000 m thick and form a thin slice, striking 340°M and with near vertical dips, sandwiched between sediments of the (?) Lower-Middle Silurian Bumbowlee Creek Beds on both the east and west. The western boundary is a fault contact, but in the east the Blowering Beds lie conformably on the Bumbowlee Creek Beds. Regionally, these rocks form part of the western limb of a major south?south-east trending anticline that plunges steeply to the south.
