摘要

澳大利亚中部的马斯格雷夫省是长期地幔上涌的焦点,产生了大量镁质玄武岩到拉斑岩浆及其长英质衍生物。马斯格雷夫省拥有全球最集中的基性-超基性层状侵入体之一,被归类为吉尔斯侵入体。本文研究了南澳大利亚Kalka、Gosse桩和Ewarara层状侵入体的岩浆成矿潜力。Ewarara和Gosse Pile的铂族元素(PGE)礁和岩浆Ni-Cu礁的潜力相对较低,这主要是由于缺乏明显的金属富集和镁铁质-超镁铁质过渡带,而镁铁质-超镁铁质过渡带是全球大多数PGE礁的栖息地。然而,侵入体中可能具有较高找矿潜力的镁铁质-超镁铁质管道尚未被研究。在Kalka,暴露了基性-超基性过渡层,使得这种入侵具有潜在的PGE礁前景。然而,根据现有的数据,这个区域似乎是贫瘠的。相反,在含磁铁矿的侵入体上部有PGE富集和金属比变化的迹象,提示未发现的PGE生物礁。这一解释与侵入体上部邻近土壤的微量Cu-Pd富集相一致。南澳大利亚Kalka、Ewarara和Gosse桩层状侵入体岩浆成矿潜力首次评价。在岩体上部含磁铁矿部分,Kalka显示出PGE富集的迹象,表明PGE礁的可能性增强。Ewarara和Gosse Pile似乎对PGE-Ni-Cu的前景不太乐观,但苦橄岩管道仍未被研究。

Petrogenesis of the Kalka, Ewarara and Gosse Pile layered intrusions, Musgrave Province, South Australia, and implications for magmatic sulfide prospectivity
Abstract The Musgrave Province of central Australia was the focus of long-lived mantle upwelling that produced large volumes of magnesian basaltic to tholeiitic magma and their felsic derivatives. The Musgrave Province contains one of the greatest concentrations of mafic–ultramafic layered intrusions globally, grouped as the Giles intrusions. In the present paper, we study the magmatic ore potential of the Kalka, Gosse Pile and Ewarara layered intrusions located in South Australia. Ewarara and Gosse Pile appear to have relatively low potential for platnium-group element (PGE) reefs and magmatic Ni–Cu, based on lack of evident metal enrichment and the absence of a mafic–ultramafic transition zone that hosts most PGE reefs globally. However, mafic–ultramafic pipes within the intrusions that could have higher ore potential have not been studied by us. At Kalka, the mafic–ultramafic transition interval is exposed, rendering this intrusion potentially more prospective for PGE reefs. However, based on the available data, this zone appears to be barren. Instead, there are signs of PGE enrichment and metal ratio variation in the magnetite-bearing upper portion of the intrusion suggestive of undiscovered PGE reefs. This interpretation is consistent with subtle Cu–Pd enrichment of soils adjacent to the upper portion of the intrusion. KEY POINTS First assessment of magmatic ore potential of Kalka, Ewarara and Gosse Pile layered intrusions in South Australia. Kalka shows signs of PGE enrichment in upper, magnetite-bearing portion of intrusion, suggesting enhanced potential for a PGE reef. Ewarara and Gosse Pile appear to be less prospective for PGE–Ni–Cu, but picrite pipes remain unstudied.

期刊介绍: Australian Journal of Earth Sciences publishes peer-reviewed research papers as well as significant review articles of general interest to geoscientists. The Journal covers the whole field of earth science including basin studies, regional geophysical studies and metallogeny. There is usually a thematic issue each year featuring a selection of papers on a particular area of earth science. Shorter papers are encouraged and are given priority in publication. Critical discussion of recently published papers is also encouraged.
