Petrographic Study of the Pacoota Sandstone, Amadeus Basin, Northern Territory

Abstract

A total of 61 thin-sections were examined in this study and one sample was analysed by x-ray diffraction methods. Eighteen of the thin-sections were prepared as part of this project; the rest had been prepared earlier and were supplied with the samples. The majority of samples used in this study were arenites with only three carbonate rocks and five mudrocks inclduded. Most of the samples came from outcrop sections but a small number were subsurface samples from P3B subunit in the Mereenie Field. All subunits of the Pacoota Sandstone (P1-P4) were represented in the surface samples.
