SEDIMENTARY METAMORPHOSED BAUXITES OF THE PROVINCE JAMMU (INDIA) AS PRODUCTS OF REDEPOSITION OF DIFFERENT LATERITIC WEATHERING ROCKS
India is rich in bauxite deposits, especially, lateritic ones. At the same time, there are sedimentary and metamorphosed deposits, which genesis and sources of ore substance were unknown remained for a long time. The Cretaceous-Eocene bauxites of the Jammu and Kashmir State are situated in the foothills of the Himalayas and related to such objects. The results of the carried out investigations with application of SEM let us speak with confidence on some vague and discussion questions, concerning the composition and origin of these bauxites. The ore substance is bimineral and consists of diaspore and boehmite. Diaspore predominates in debris of the pseudomorphous lateritic bauxites, cavernous and porous cement and film secretions between cement and pisolites. Boehmite prevails in the dense cement and concretions. Bauxites are products of redeposition of laterized traps, quartz-muskovite-chlorite-feldspar slate, agglomerates and phosphorites. The obtained results of the study of the sedimentary metamorphosed kaolins and bauxites, as well as lateritic bauxites, are of great importance for theory of the origin of the similar objects on the territory of Russia.
