The preponderance of early cementation and brecciation towards the top of the Langport Member is compatible with reduced sedimentation rate. |
The paucity of outcrop in the Acraman depression indicates that the bedrock beneath the depression is strongly disrupted by brecciation and jointing. |
Brecciation likely occurred during both excavation and modification stages. |
The mineralization appears to be located at the intersection of two regional structural trends where deformation has produced intense cataclasis and brecciation. |
Lamination, brecciation, and other sedimentary features of the dolomite are well preserved in this massive sheet of microcrystalline quartz. |
The thrust zone displays significant brecciation although no slip planes were located. |
