Redox conditions in the earth's upper mantle and the implications for kimberlite petrogenesis, diamond formation and mantle metasomatism.

钻石是一种重要的高价值商品。就克拉而言，澳大利亚是世界领先的生产国，这主要是由于西澳大利亚州北部的大量Argyle矿藏。虽然钻石形成于地球的很深处，但在地表是可以接触到的，因为它们是由稀有的火山岩、金伯利岩和角闪岩运输的。尽管这些岩石很重要，但人们对它们的成因知之甚少。这项研究将解决这一问题，为钻石及其宿主火山岩的形成模型提供科学约束，这将直接为采矿业的勘探模型提供信息。从勘探支出的更成功结果来看，将给国家带来经济利益。

Diamonds are an important and high value commodity. Australia is the world's leading producer in terms of carats, due mainly to the massive Argyle deposit in northern Western Australia. Although diamonds form at great depths in the earth, they are accessible at the surface because they are transported by rare volcanic rocks, kimberlites and lamproites. Despite their importance the genesis of these rocks is poorly understood. This research will address this, providing scientific constraints on models for formation of diamonds and their host volcanics, which will directly inform the minerals industry's exploration models. There will be an economic benefit to the nation in terms of more successful outcomes from exploration expenditure.
