Abstract

This preliminary report deals with examination and classification of Ordovician, Middle and Upper Devonian limestone samples collected in the Fitzroy Basin during August, September and October of 1953. The geology of the area has recently been described by Guppy (1953). Rocks are designated by their field numbers, as geologists of West Australian Petroleum Limited, in conjunction with whom the collection was made, have retained the numbers for reference. For purposes of petrographic discussion, the nomenclature of clastic limestones as set out by Condon (1953) is used. Basic information sought in investigations of most limestones concerns: 1) Composition: distinction between calcite and dolomite is important; [and] 2) Origin: the origin of many limestones is very complex, but division into clastic, organic or chemical limestone should be attempted. Texture, both as observed under the microscope and in handspecimens is very useful, but in some cases (especially bioherms) field evidence supplies the only criterion. This paper has two main sections. The section on determination of composition describes techniques for distinction between calcite and dolomite, and the section on description of specimens incorporates suggestions about origin and environment of deposition where these logically arise from examination of textural or other features. 78 thin sections were examined, and textures typical of limestones of the area are illustrated by photomicrographs.
