在矿物、岩石、矿床、地球化学等方面,反映氧化还原条件的氧逸度,日益受到人们的重视.本文就氧逸度、氧缓冲剂、氧逸度的估算以及氧逸度在岩矿方面的应用,概述如下. 氧逸度及氧缓冲剂(一)氧逸度的概念氧逸度fo_2(Oxygen fugacities)就是有效的氧分压.氧分压(Partial oxygen pressure)是指混合气体总压之下的氧的分压力,以Po_2表示.举一个最简单的例子来说,如果把空气的总压力看作是一个大气压(atm),而空气的
In the fields of minerals, rocks, mineral deposits, geochemistry and so on, the oxygen fugacity which reflects the redox conditions is paid more and more attention by people.In this paper, oxygen fugacity, oxygen buffer, oxygen fugacity, Oxygen fugacity and oxygen buffering agent (a) the concept of oxygen fugacity oxygen fuzz fo_2 (Oxygen fugacities) is the effective partial pressure of oxygen (Partial oxygen pressure) refers to the total pressure of the mixed gas Under the partial pressure of oxygen to Po_2. For the simplest example, if the total pressure of the air as a pressure (atm), while the air
