| The available evidence suggests the possibility of karst dissolution, collapse and brecciation, followed by lithification. |
| The host lithology is a dolomitic unit that has undergone stylolitic quartz and manganese veining and brecciation. |
| Locally, intense brecciation gave rise to angular vein quartz fragments enveloped by a matrix of massive hematitic rock. |
| The paucity of outcrop in the Acraman depression indicates that the bedrock beneath the depression is strongly disrupted by brecciation and jointing. |
| The brecciation and width of mineralization appears to be increasing to the west and at depth. |
| Lamination, brecciation, and other sedimentary features of the dolomite are well preserved in this massive sheet of microcrystalline quartz. |
