Abstract

In order to elucidate partition behavior of divalent cations between minerals and aqueous chloride solutions under supercritical conditions of fluid phase, we conducted experiments of the simultaneous partitioning of Ni2+, Mg2+, Co2+, Zn2+, Fe2+, and Mn2+ between löllingite (FeAs2) or safflorite (CoAs2) and 2 mol/L aqueous chloride solutions under the conditions of 500 and 600 °C, 100 MPa. Natural löllingite and safflorite were used as starting materials. The bulk partition coefficient (KPB) for the cation partition reactions can be expressed as follows:

超临界条件下二价阳离子在löllingite或红花铁矿与2mol/l氯化物水溶液之间同时分配的实验研究

为了阐明二价阳离子在超临界流体相条件下在矿物和氯化物水溶液之间的分配行为，我们进行了在500和600°C，100MPa的条件下，Ni2+、Mg2+、Co2+、Zn2+、Fe2+和Mn2+在löllingite（FeAs2）或红花铁矿（CoAs2）和2mol/l氯化物水溶液中同时分配的实验。以天然绿柱石和红花红柱石为起始原料。阳离子分配反应的体积分配系数（KPB）可以表示如下：

期刊介绍： The Journal of Mineralogical and Petrological Sciences (JMPS) publishes original articles, reviews and letters in the fields of mineralogy, petrology, economic geology, geochemistry, planetary materials science, and related scientific fields. As an international journal, we aim to provide worldwide diffusion for the results of research in Japan, as well as to serve as a medium with high impact factor for the global scientific communication Given the remarkable rate at which publications have been expanding to include several fields, including planetary and earth sciences, materials science, and instrumental analysis technology, the journal aims to encourage and develop a variety of such new interdisciplinary scientific fields, to encourage the wide scope of such new fields to bloom in the future, and to contribute to the rapidly growing international scientific community. To cope with this emerging scientific environment, in April 2000 the journal''s two parent societies, MSJ* (The Mineralogical Society of Japan) and JAMPEG* (The Japanese Association of Mineralogists, Petrologists and Economic Geologists), combined their respective journals (the Mineralogical Journal and the Journal of Mineralogy, Petrology and Economic Geology). The result of this merger was the Journal of Mineralogical and Petrological Sciences, which has a greatly expanded and enriched scope compared to its predecessors.
