Textural characteristics and clay mineralogy of the 'Red Beds' from the Khanapur Palateau, Maharashtra, India

Textural Characteristics, Red Beds, Detrital And Transported In NatureAbstract
The Khanapur plateau surface is consisting chiefly of 'Red beds' which rest uncomfortably over the bed rock basalt which has its weathering profiles. They occurs fan-shaped sedimentary deposits especially in the area around Menganwadi village, Balavadi and Adsadwadi. The sediment can be considered as heterogeneous mixture of various sizes with dominance of fine grained materials. The poorly to very poorly sorted nature of ‘Red beds' indicate that the sediments are most probably deposited in fluvial environment as traction current due to river action. Mineralogy, the XRD and IR and microscopic analysis were used for four constituents; clayey materials, opaques, lithic fragments and iron oxides. However, thus detrital natural minerals have reveal as well as effects of weathering, erosion and transportation. The secondary precipitation of silica and calcite has been taken place along the fractures, bedding planes and cavities or voids in the strata. The SEM show the dominance of
