东昆仑热液矿床的流体包裹体特征

Characteristics of the fluid inclusion in hydrothermal deposit of the east Kunlun

东昆仑地区矿产资源丰富,是我国重要的金属成矿带。区内岩浆活动强烈,从元古代到中生代间歇性火山喷发与岩浆侵入频繁交替,因此形成了数量繁多,种类各异的热液型矿床。通过总结前人的研究,将各种热液矿床分类为4种:造山型、浆控高温热液型、浅成低温热液型和热水沉积型。然后分别介绍了这四种热液矿床的流体包裹体特征,并总结各类矿床的差异,使分类更加简洁明了。

East Kunlun area is rich in mineral resources,which is an important metallogenic belt in China.The magmatic activity is intense in east Kunlun,and the intermittent volcanic eruption and magmatic intrusion alternated frequently from Proterozoic to Mesozoic.As a result,a large number of different types of hydrothermal deposits have been formed.By summing up previous studies,various hydrothermal deposits are classified into four types:orogenic or metamorphic deposit,intrusion-related hypothermal deposit,epithermal-type deposit,and hot-water deposit.Then,the fluid inclusion characteristics of four kinds of hydrothermal deposits are introduced,and the differences of four kinds of deposits are summarized to make the classification clearer.
