PREFACE In compliance to the Notification issued by the Ministry of Environment and Forest and Climate Change notification No. S.O. 3611 (E) New Delhi dated 25-07-2018, the preparation of District Survey Report of river sand mining in accordance with Appendix X of the Notification. Every effort have been made to cover sand mining locations, areas and overview of mining activity in the district with all its relevant features pertaining to geology and mineral wealth in replenishable and non-replenishable areas of rivers, stream and other sand sources. This report will be a model and guiding document which is a compendium of available mineral resources, geographical set up, environmental and ecological setup of the district and is based on data of various departments, study conducted by renowned institutions, published reports and websites.
