On my second visit to Lake Cowal back in early December, I was told about a place that was of great interest to geologists visiting the nearby gold mine. This trip I headed out to have a look.
Following is the information I was given to explain what I was going to see.
"The outcrop is part of the Booberoi Fault and features sheared Late Silurian-Early Devonian Edols Conglomerate (Sherwin, 1996) showing stretched quartzite and vein-quartz pebbles in a quartz white mica-chlorite matrix, which was probably a muddy sandstone. Mesoscopic kinematic indicators show at least two movement episodes: a horizontal sinstral movement and a near vertical reverse (west side up) movement. The movement direction can be discerned from the asymmetry of the matrix surrounding the pebbles and the mineral elongation within the matrix."
