  Platinum-group elements for the Kudi ophiolite, western Kunlun

  摘要：

  The analyses of PGE characteristics for the Kudi ophiolite, western Kunlun, are reported in this note. The Ir-depleted anomalous ancient upper mantle represented by the Kudi mantle peridotites had been percolated and mixed by remelted oceanic crust material from a supra-subduction zone, leaving the rocks relatively enriched in Pd. The PGE contents in the Kudi cumulate pyroxenites and gabbros vary from 2.4 to 23.94 ng/g, and the highest values are in pyroxenites. The Pd/Ir ratios increase from the pyroxenites to the gabbros. The PGE patterns for the Kudi cumulate rocks are steeply positively sloped. The Pd enrichment in these rocks is similar to that in pyroxenites from the Thetford ophiolite and the Troodos ophiolite. The Kudi diabase and basalts have low PGE contents and positively sloped PGE patterns, and are comparable with the upper pillow lavas from the Troodos ophiolite, indicative of the environment of back-are spreading center in a supra-subduction zone.

  公开号：US04162946A1

  公开（公告）日：1979-07-31

  A process for concentrating at least one of (a) individual halogenoanthraquinones (b) binary mixtures of di-halogenoanthraquinones and (c) binary mixtures of trihalogenoanthraquinones, from a mixture containing at least two halogenoanthraquinones, comprising subjecting said mixture containing at least two halogenoanthraquinones to fractional vacuum distillation in a heated rectification column having an efficiency corresponding to about 20 to 50 theoretical stages with an absolute pressure at the top of about 0.5 to 50 mm Hg and a reflux to take-off ratio of about 5/1 to 50/1. Advantageously, distillation is carried out continuously in a cascade of columns, the products withdrawn from the top of the first column being 2-chloroanthraquinone in the first stage, 1-chloroanthraquinone in the second stage, 1,6- and 1,7-dichloroanthraquinone in the third stage and 1,5- and 1,8-dichloroanthraquinone in the fourth stage, 1,4,5- and 1,4,6-trichloroanthraquinone being obtained in the sump of the 4th stage and being separated therefrom by film evaporation. The mixture of halogenoanthraquinones is advantageously a mixture of chloroanthraquinones such as is obtained by the action of chlorine, chloric acid or a chlorate on various industrial mixtures of nitro- or sulfo-anthraquinones.
