| The available evidence suggests the possibility of karst dissolution, collapse and brecciation, followed by lithification. |
| Progressive intrusion and hydraulic fracturing gave rise to local brecciation of the banded rocks. |
| The mineralization appears to be located at the intersection of two regional structural trends where deformation has produced intense cataclasis and brecciation. |
| The paucity of outcrop in the Acraman depression indicates that the bedrock beneath the depression is strongly disrupted by brecciation and jointing. |
| Locally, intense brecciation gave rise to angular vein quartz fragments enveloped by a matrix of massive hematitic rock. |
| The host lithology is a dolomitic unit that has undergone stylolitic quartz and manganese veining and brecciation. |
