THE BIOLOGICAL SURVEY OF THE EASTERN GOLDFIELDS OF WESTERN AUSTRALIA: Discussion

WA Museum Records and Supplements | Updated 9 years ago

Introduction: The Jackson-Kalgoorlie Study Area is a topographically diverse region and contains seven of the 10 landform units encountered in the Eastern Goldfields. The Helena and Aurora Ranges are excellent examples of Hill (banded ironstone formation)(Figure 4, Plate 4). Bungalbin Hill, at 684 m in the Aurora Range, is the lii"ghest point in the region. Undulating Plain (greenstone), Broad Valley and Salt Lake Feature are also well represented, while the extensive areas of Sandplain contain important admixtures of the south-western and arid floras. Granite Exposure is more frequent in the western portion of the Study Area and there are a few small breakaways. Mt Walter was the only occurrence of Hill (quartz) noted during field work.
