Menterang Formation Sediments<br />
The Menterang Formation in <strong>the</strong> project area is composed <strong>of</strong> shales <strong>and</strong> argillite, being light to<br />
dark grey in colour when fresh, in 2-15 centimetre thick beds. Sometimes grey s<strong>and</strong>stones to<br />
75cm thick underlie shale b<strong>and</strong>s. The thin shale sequence with occasional s<strong>and</strong>stone couplets<br />
is typical <strong>of</strong> distal turbidites. In some areas, thick sedimentary breccia, composed <strong>of</strong> r<strong>and</strong>omly<br />
distributed angular fragments <strong>of</strong> shale approximately 10 centimetres in size in a light grey clay<br />
matrix possibly represent slump zones in <strong>the</strong> distal turbidite sequence. This argillite sequence is<br />
characterised by strong presence <strong>of</strong> <strong>the</strong> S1 cleavage which in places turns <strong>the</strong> rock into a slate.<br />
