通过测量稳定同位素来说明热液中水的成因和历史是一项较新的技术.现代着重于研究雨水在许多热液矿床(包括许多产于断裂火山岩层中的浅成低温热液含金金属矿床)的形成中的重要作用.认为别的脉型金矿是由岩浆或变质成因的矿液形成的,且具有特征的δO~(18)值.而澳大利亚东部一些重要的金矿床的初步的氧、碳同位索资料则着重于它们矿液的不同来源.现已证实芒特摩根(MountMorgan)金一铜矿体属火山成因的块状硫化物型矿床,其矿液以海水为其主要来源.查尔特斯托威尔斯(Charters Towers)裂隙脉形成于热液(此热液与洛瓦斯—Lolworth火成杂岩体的侵入活动有成因联系)活动期.斯特韦尔(StaWell)和京比(Gympie)石英脉的氧同位素研究未取得结果.矿液的δO~(18)值约为70%,可能为岩浆或变质作用的产物.
It is a relatively new technique to illustrate the origin and history of water in hydrothermal fluids by measuring stable isotopes.Modern emphasis on the study of rainwater in many hydrothermal deposits, including many epithermal gold-bearing metals from fault volcanic formations Ore deposits) .It is believed that other vein-type gold deposits are formed by magmatic or metamorphic ore fluids and have characteristic δO ~ (18) values.And some important gold deposits in the eastern part of Australia Oxygen and carbon isotopic data are focused on different sources of their ore fluids and it has been confirmed that the MountMorgan gold-copper ore body is a volcanogenic massive sulphide-type deposit with seawater as its main source The Charters Towers fractures formed in the hydrothermal fluid that is causally linked to the intrusive activity of the Lovas-Lolstock complex, and Stawell, And the quartz isotopes of Gympie quartz veins have not been obtained.The δO ~ (18) value of ore fluid is about 70%, which may be the product of magmatic or metamorphism.
