Age constraints on Tarkwaian palaeoplacer and lode gold

Two major epigenetic gold-forming events are recorded in the world-class gold province of southwest Ghana. A pre-Tarkwaian event was the source of the world-class Tarkwa palaeoplacers whereas post-Birimian and Tarkwaian deformation, which was related to the Eburnean orogeny, gave rise to the world-class (e.g. Prestea) to giant (e.g. Obuasi) orogenic gold deposits which have made the region ...

The Red Wing prospect is one of many auriferous lodes at the head of Windham Bay, most of which have been known since at least 1904 (Wright and Wright, 1906; Kimble and others, 1984). The prospect consists of a caved adit at least 75 feet long that extends to a stope that has been mined vertically for less than 10 feet (Kimble and others, 1984).

Gold mineralization is hosted primarily by Archean-aged dolerites and basalts that have been metamorphosed to the greenschist facies. This mineralization occurs in hundreds of auriferous and telluride-bearing lodes, which have been classified into three structural types on the basis of orientation: main (trending NNW), caunter (trending NW) and ...

The lodes are quartz veins and stringers that contain auriferous pyrite, galena, sphalerite, and chalcopyrite and lesser amounts of gold tellurides, tetrahedrite, argentite, and stibnite. Most of the ore shipped was oxidized and consisted of gold and free silver in quartz, iron oxides, manganese oxides, and a little locally occurring copper stain.

Gold mineralization at the Ballarat East deposit, central Victoria, Australia, is hosted in lodes that are historically known as “leather jackets.” These are quartz-dominant vein arrays related to low-displacement, W-dipping faults (≤45 ) that transect the core and/or eastern limb of tight, asymmetric N-S-trending anticlines.
