Geology of Dasam Falls in Ranchi district of Jharkhand State, India.

 The Dassam Fall is a natural cascade across the Kanchi River. by Dr. Nitish Priyadarshi Geologist A waterfall is a place where water flows over a vertical drop in the course of a stream or river. Waterfalls are also called cascades. Waterfalls are commonly formed when a river is young. At these times the channel is often narrow and deep. When the river courses over resistant bedrock, erosion happens slowly, while downstream the erosion occurs more rapidly. As the watercourse increases its velocity at the edge of the waterfall, it plucks material from the riverbed. Whirlpools created in the turbulence as well as sand and stones carried by the watercourse increase the erosion capacity. This causes the waterfall to carve deeper into the bed and to recede upstream. Often over time, the waterfall will recede back to form a canyon or gorge downstream as it recedes upstream, and it will carve deeper into the ridge above it. The process of erosion, the wearing away of earth, plays an im...

Pollution is the the big threat. by Dr. Nitish Priyadarshi nitish.priyadarshi@gmail.com Physiography : The spatial extent of Jharkhand State is approximately 21° 55’ to 25° 35’ North Latitude and 83° 20’ to 88° 02’ East Longitude. The state is land locked and it shares its boundary with Orissa on the southeast, Chattisgarh on the southwest, Bihar on the north, West Bengal on the east and Uttar Pradesh on the northwest. It comprises of the Chotanagpur Plateau, which forms a part of Deccan bio-geographic province. It is a hilly undulating plateau characterized by predominantly tropical forests and tribal settlements. The State is endowed with natural resources that need to be conserved and utilized in a sustainable manner for all-round development of the state in general and the marginalized tribal population in particular. The total geographical area of the State is 79.70 lakh hectares, out of which 23.22 lakh hectares (29.33%) are under forests; 5.66 lakh hectares (7.12%) are barren ...

Fuller’s earth mining in Pakur district in Jharkhand State of India.

Bentonite may have played a major role in Fuller’s earth formation. By Dr. Nitish Priyadarshi   Fig. Mining of Fuller's earth.  Fig. Fuller's earth.  Fig. Mining area. Fig. Bentonite. Abstract: Pakur   is located in the north east corner of Jharkhand State of India. Major part of the district is characterized by undulating topography covered by basaltic flows of Rajmahal Trap. Fuller’s earth mining is limited up to a shallow depth only and it is done manually. Most of the Fuller’s earth is send to local market of Pakur and neighboring state of West Bengal. Local villagers have the ownership of the mining and the profit is distributed among them. Fuller’s earth is mainly of sedimentary origin. It occurs interstratified with geologically late sands and clays. It is thought that most fuller’s earth originated from volcanic ash. Montmorillonite and attapulgite are the principal constituents, and montmorillonite is characteristic of bentonite. There is further suggestio...
