ON THE KERATOPHYRE-SPILITIC FORMATION OF THE SOUTH-YENISEY MOUNTAIN RIDGE AND THE POSSIBLE NATURE OF THE KASSKAYA MAGNETIC ANOMALY.

Abstract

The translation is of a work which drew the following conclusions: (1) The Yenisey metamorphic complex, or at any rate a considerable part of it, represents a metamorphized keratophyre-spilitic formation. (2) Ferrour quartzites are spatially and genetically connected with similar Pre-Cambrian formations of the world. (3) Rocks of the keratophyre-spilitic formation of Southern Yenisey ridge subside in a northwestern direction. These formations and higher horizons of the above-indicated formation obviously compose the Pre-Cambrian basement of the West-Siberian lowland in the region of the Kasskaya magnetic anomaly. (4) All that has been mentioned above indicates the possible occurrence of ferrons quartzites in the Pre-Cambrian foundation of the West-Siberian lowland in the region of the eastern part of the Kasskaya magnetic anomaly. (5) It is possible to assume that in Central Siberia there is located a basin of iron ore similar to that of the Kursk-Kriway Rag Basin. (Author)
