Abstract

The paper presents results of a study of middle crustal (amphibolite-facies level) desilicated rocks exemplified by corundum-bearing plagioclasites developing after metabasites at the unique Khitostrov corundum deposit in the Belomorian–Lapland orogen of the Fennoscandian shield, with emphasis placed onto newly acquired geological data, documentation and analysis of the metasomatic zoning, determination of the P–T conditions of its formation, and a model of the metasomatic process.

闪长岩向含刚玉斜长岩的变质转化：以芬诺斯坎地盾独特的希托斯特罗夫刚玉矿床为参照，对这一过程进行分区并建立数值模型

本文介绍了在芬诺斯坎地盾Belomorian-Lapland造山带Khitostrov刚玉矿床中，以变质岩后发育的含刚玉斜碎屑岩为例的中地壳(角闪岩相水平)脱硅岩的研究结果，重点介绍了新获得的地质资料、交代带的记录和分析，确定了其形成的P-T条件，并建立了交代过程模型。

期刊介绍： Petrology is a journal of magmatic, metamorphic, and experimental petrology, mineralogy, and geochemistry. The journal offers comprehensive information on all multidisciplinary aspects of theoretical, experimental, and applied petrology. By giving special consideration to studies on the petrography of different regions of the former Soviet Union, Petrology provides readers with a unique opportunity to refine their understanding of the geology of the vast territory of the Eurasian continent. The journal welcomes manuscripts from all countries in the English or Russian language.
