Lithostratigraphy of Bar-Mohra Khurd-Raira Khurd Area of Pali District, Rajasthan and their Relationship with the Soil and Vegetation

The paper deals the study a metasedimentary sequence, overlying schistose formation of Sendra Formation of Delhi Supergroup and the underlying Banded Gneissic Complex of Pre-Delhi age, in Birantiya Khurd -Raira Khurd areas in northwestern Rajasthan. The sequence is important due to its heterogenous lithologic association. It shows by different type of conglomerates imbedded in quartzofeldspathic schist. The process of soil formation by breaking up the rock particles and organic matter from weathering and erosion of subterranean parts are influenced by different biological activity. This sequence has been defined as the 'Bar conglomerate horizon' in this paper. The soils derived from the parent rocks which sustain different vegetation, depends upon the climatic conditions. Hence, the nutritional status is required to be studied from the point of view of sustenance of flora in the area. There is no clarity, so far, regarding the exact chronology of deformation in the area. At the same time, the lithostratigraphic history of the area also needs a further revision. In view of the above, the Bar-Mohra Khurd-Raira Khurd area have been studied extensively and results are presented in this paper.
