澳大利亚中南部维多利亚大沙漠的沙子根据其物理和化学特征（颜色、粒度参数、重矿物组的矿物学、石英氧同位素组成、锆石 U-Pb 年龄）可分为三大类。这些群体分别占据了维多利亚大沙漠的西部、中部和东部，它们之间的边界大致对应于与耶尔加恩克拉通到官员盆地到阿卡林加盆地相关的底层岩石的变化。一些证据表明，沙子主要来自当地的基岩，随后的风作用很少。沙子的最终原始来源（按重要性排序）是：大维多利亚沙漠西部 - 伊尔加恩克拉通、奥尔巴尼-弗雷泽造山带、马斯格雷夫杂岩；维多利亚大沙漠中部——马斯格雷夫综合体；大维多利亚沙漠东部——高勒和库纳莫纳区块、阿德莱德地槽、马斯格雷夫综合体。来自阿德莱德地槽的沉积物还包括...
Sands of the Great Victoria Desert, south‐central Australia, can be divided into three main groups on the basis of their physical and chemical characteristics (colour, grainsize parameters, mineralogy of heavy‐mineral suites, quartz oxygen isotopic composition, zircon U–Pb ages). The groups occupy the western, central and eastern Great Victoria Desert respectively, boundaries between them corresponding approximately to changes in the underlying rocks associated with the Yilgarn Craton to Officer Basin to Arckaringa Basin. Several lines of evidence suggest derivation of the sands mainly from local bedrock with very little subsequent aeolian transport. Ultimate protosources for the sands, each in order of importance, are: western Great Victoria Desert—Yilgarn Craton, Albany‐Fraser Orogen, Musgrave Complex; central Great Victoria Desert—Musgrave Complex; eastern Great Victoria Desert—Gawler and Curnamona Blocks, Adelaide Geosyncline, Musgrave Complex. Sediment from the Adelaide Geosyncline includes in additi...
