摘要:

深部碳循环是全球碳循环研究中不可或缺的部分。较之表层碳,人类对地球深部碳储库的储量、碳的迁移方式和交换量都缺乏清晰认识。作为来自地球深部的碳单质矿物,金刚石是研究深部碳循环的绝佳样品。近年来原位微区分析技术的突飞猛进为研究金刚石及深部碳循环提供了良好条件。文中对表层与深部碳交换、深部碳储库及金刚石矿物学性质进行了介绍,并通过金刚石及其包裹体的稳定同位素组成,探讨了金刚石的形成机制及含碳流体/熔体的性质与来源问题。

关键词: 金刚石, 深部碳循环, 稳定同位素, 包裹体

Abstract:

Deep carbon cycle is an indispensable part of global carbon cycle. While extensive research has been done on surface carbon cycle, there is still little understanding of the carbon in deep earth. We do not know how much carbon is stored in deep repository, nor do we quantify the migration of carbon between different repositories and its exchange with earths surface. As a simple substance mineral of carbon from deep earth, diamond is a wonderful window of glimpsing deep carbon cycle. Recent rapid development of insitu microanalysis techniques provides strong support for diamond and deep carbon cycle research. This article makes a brief introduction on carbon exchange between surface and deep earth, deep carbon repositories and mineral characteristics of diamond. Subsequently, a discussion is made for mechanism of diamond formation, characteristics and sources of deep earths carboncontaining fluid/melt through stable isotopes compositions of diamond and its inclusion.

Key words:  , diamond, deep carbon cycle, stable isotopes, inclusion
