The iron deposits occur in roughly parallel ranges of hills, Ironback Range to the north-west, and Little Ironback Range to the south-east. These both have a roughly NE-SW trend, and are about 5 to 7 miles apart, with some small undulating hills and much alluvial material in between. The iron deposits were examined with a view to discussing their origin and associations. The beds were not mapped on this visit (May 1949) but it is hoped to be able, at a later date, to return and map the beds in detail. Thus at present, no indication as to their possible future economic utilization can be given. The deposits were inspected at 3 general localities (see sketch map attached). Loc. A: Ironback Range, approx. 2 miles east of Braemar-Tiverton track. Loc. B: near the southern tip of the Little Ironback Range. Loc. C: about half mile north of Loc. B. Loc. D: about 1 mile north of Loc. C. Loc. E: About 300 yards east of Braemar H.S. The following Sections are also attached:- Section 1. Diagrammatic Section from Little Ironback Range to Ironback Range. This is very generalised, and at present only represents the probable structure. Section 2. Generalised Section of the Little Ironback Range, Loc. D. Section 3. More detailed section at Loc. C, Little Ironback Range. Sections 2 and 3 show thicknesses which are approximate only, the profiles also being diagrammatic.enHonours; Geology; Adelaide Geosyncline; Sturtian; iron formations; hematite; petrography; chemistryThesis
