Summary:

Yandicoogina: goethite mineralisation occurs as pisolite ores within the paleo-channel of a channel iron formation.

The Yandicoogina area consists of Proterozoic basement rocks of the Hamersley Group. The majority of the outcrop being the Weeli Wolli Formation, comprising jaspilite and shale. The Weeli Wolli Formation is overlain by relatively thin Tertiary and Quaternary sediments. The basement rocks comprise Banded Iron Formation (BIF), chert, shale and volcanic rocks. The thin alluvium and colluvium cover consists of valley fill and recent alluvium deposits, which includes the CID, and are restricted to areas close to present drainages.

The Proterozoic basement rocks have been faulted and folded into a gently synclinal structure called the Yandicoogina Syncline which controls the geomorphology and ultimately the location of the CID and present drainage system. Fractured basement rocks and their weathered profile underlie and enclose the CID and are hydraulically connected to the CID aquifer.

The CID consists of pisolitic clasts of goethite-hematite, clay and fossil wood fragments with an approximately average thickness of 60m. The CID clasts (peloids) are typically irregular or sub-angular to sub-rounded in shape. These iron rich peloids are interpreted to represent the end product of detrital weathering via sheet wash processes deposited in low lying areas (Ramanaidou, et al, 2003).

The modern drainage of the Yandicoogina, Marillana, Weeli Wolli Creeks and other tributaries contain unconsolidated conglomerates (river gravels) up to 5m thick. The river gravels contain boulder to gravel size clasts comprising mainly BIF, shale, siltstone, chert, dolerite and minor calcrete and duricrust.
