AUSTRALITES FROM MOUNT REMARKABLE STATION AND ADJOINING PARTS OF YERILLA STATION, WESTERN AUSTRALIA

WA Museum Records and Supplements | Updated 1 decade ago

Abstract: Collections of australites totalling 926 specimens found on Mount Remarkable and Yerilla Stations in the semi-arid interior of Western Australia have been examined. The more representative units within those collections totalling 476 australites were used for studies of morphology, specific gravity and mean weights. Most of the australites are badly abraded, weathered or broken, only 53% being morphologically classifiable. The frequency diagram of specific gravity has a single mode in the 2.45-2.46 interval and no values above 2.47, suggesting that the australites belong to the 'normal australite' chemical type. The mean weight of whole australites is 4.74 g and of all specimens 2.73 grams.
