Olgers, F., 1961. The geology of the Machattie 4-mile sheet area, Queensland. Record  1961/061. Bureau of Mineral Resources, Geology and Geophysics, Canberra.

Abstract

The Machattie 4-mile Sheet area in western Queensland was mapped in 1960. Surface mapping and examination of water bore logs established a sequence of at least 2750 feet of Cretaceous rocks, which are, in places, unconformably overlain by up to 55 feet of Tertiary sediments. Possible basement rocks were struck in Cluny No. 1 and Coorabulka No. 10 bores. The Cretaceous rocks form the main aquifer and impermeable cap of the western portion of the Great Artesian Basin. The Lower Cretaceous shales of the Wilgunya Formation are possible source rocks for petroleum. Source rocks also occur in the Lower Palaeozoic succession to the north, in the Boulia 4-mile Sheet area. The sandstones of the Lower Cretaceous Longsight Sandstone are possible reservoir rocks in the Machattie area. Neither oil nor gas has been recorded from any of the bores (11 artesian, 2 sub-artesian). Showings were reported from the Bedourie Bore, 5 miles west of the area, and from Delhi-Frome-Santos Betoota No. 1 Well , 50 miles south of the Machattie area. A major north-east trending structure is present in the north-east corner of the area. It is possibly a continuation of the structure against which the Burke River Structure terminates in the Springvale 4-mile Sheet area, north of the Machattie area. No economic mineral deposits are present in the area
