摘要
在湘西—黔东汞矿带中,硒主要替代硫以类质同象的形式存在于辰砂中,少部分见于黑辰砂和硒汞矿中。辰砂中硒含量的高低与其颜色、晶形、粒度、生成期以及产出部位有关。硒是湘黔汞矿带标型微量指示元素。
The occurrences of selenium of the western Hunan - eastern Guizhou mercury belt are discussed. Selenium mainly exists in cinnabar in dispersion state of impurities. A few amount is also discuvered in melano-cinnabar and tiemannite. The contents of selenium in the metallic minerals are associated with their colour, crystal form, size, formed period and formed position. Selenium is the guide trace element in the western Hunan - eastern Guizhou mercury deposit.
