Missing Coal Seam between East and West Bokaro near Lugu Hill of Damodar Basin, India: A Geological Model J. Geol. Soc. India (IF 0.899) Pub Date : 2020-09-15 Sugata Kumar Sinha, Saurabh Datta Gupta
The coal formation of the Damodar basin is found in parts of the Indian states of West Bengal and Jharkhand. However, the potentiality of the coal formation and its presence across the basin are not equal. Both East Bokaro and West Bokaro are highly fertile and productive for high-quality coal. However, due to the lack of coal seams, no significant discoveries can be made between these two regions

Rock Mass Characterization for the Underground Surge Pool Cavern — A Case Study, India J. Geol. Soc. India (IF 0.899) Pub Date : 2020-09-15 A. K. Naithani, Prasnna Jain, D. S. Rawat, L. G. Singh
Underground surge pool cavern for the storage and lifting of water is being constructed in the part of Telangana State of India. For better rock mass characterization and support design, 3D engineering geological mapping was carried for the heading portion of the surge pool. 3D geologic mapping of heading portion is very important for large underground cavern to know about the cavern behavior during

Application of CMRI-ISM RMR for Stability Analysis of Development Workings for Ballarpur Underground Coal Mine — An Empirical and Numerical Approach J. Geol. Soc. India (IF 0.899) Pub Date : 2020-08-15 Avinash Paul, Niraj Kumar, Pramod Kumar, Ashok Kumar Singh
Roof bolt failures in the mine generally occur due to the poor identification of the weak rock layers and considered as a major concern for underground coal mines in terms of its productivity and safety. The triggering factor responsible for underground roof failure is the presence of weak bedding planes and various geological discontinuities. Geological disruptions present in the mine roof seriously

Increased Ventilation of the Northern Indian Ocean during the Last Deglaciation J. Geol. Soc. India (IF 0.899) Pub Date : 2020-08-15 Sushant S. Naik, Kumari Nisha
This paper gives an overview of the deep-water ventilation studies carried out over the world oceans using radiocarbon. There is a consensus that aged water mass existing in the abyssal ocean during the last glacial, dissipated during the Heinrich Stadial 1 (HS1; 17.5–14.7 ka) and the Younger Dryas (YD; 12.9–11.7 Ka, cold event) and hence ventilation increased. The data from the Arabian Sea is in agreement

Site Suitability for RBF Using Geospatial Technology in Tungabhadra Sub-basin, India J. Geol. Soc. India (IF 0.899) Pub Date : 2020-08-15 Nagraj S. Patil, Madhu Dodawad, H. Vijaykumar, M. Nataraja
As per the 2017 global reports, 63 million Indians are living in rural areas without access to the safe drinking source of water. Access to the safe drinking water was declared as a human right by the United Nations but remains a challenge for India. Due to increase in demand of water, 30% of urban and 90% of rural households completely depend on untreated surface or groundwater, which causes serious

A Multi Criteria Approach for Morpho-tectonic Evaluation of Sai River Basin in Uttar Pradesh J. Geol. Soc. India (IF 0.899) Pub Date : 2020-08-15 Ajay Kumar Arya, Ajay Pratap Singh, Kamal Kishore Agarwal
The study integrates the morphometric analysis, lineament evaluation and fluvial geomorphology to investigate the morphotectonic setup of Sai basin. The Sai river basin forms an integral part of the central Ganga plain where the gentle slope is significantly controlled by intra-basinal tectonic activity. The fluvial setup of the Sai basin which comprises of vast old flood plains now is displayed as

Classification of the Paleoproterozoic Gulcheru Formation: Implications on Early Paleogeographic and Tectonic Evolution of the Cuddapah Basin, India J. Geol. Soc. India (IF 0.899) Pub Date : 2020-08-15 Tuasha Majumder, Sarbani Patranabis-Deb
The Papaghni sub-basin of the Cuddapah basin is an arcuate NW-SE trending intracratonic basin, stretching from Kurnool in the NW to Guvvalacheruvu in the SE, in southern peninsular India. Despite of large number of researches, an understanding of the evolution of the basin is still elusive. The sub-basin preserves records of repeated opening and closing of Paleoproterozoic rifts along the zone of NW-SE

The Deccan Volcanic Province (DVP), India: A Review J. Geol. Soc. India (IF 0.899) Pub Date : 2020-08-15 P. Krishnamurthy
Geochemical data (major and minor oxides, trace elements including REE, and Sr, Nd, Pb, and O isotopes) have been obtained on a number of flow sequences and plutonic and volcanic complexes of the DVP by numerous groups since the early 1970’s. Evaluation of these data has led to the classification of the basalts and other rock types, inferences on their mantle sources, parental magmas and the numerous

Mineralogical Studies of the Manganese Ores in Banswara Manganese Belt, Banswara District, Rajasthan J. Geol. Soc. India (IF 0.899) Pub Date : 2020-08-15 Mohd Shaif, F. N. Siddiquie, Masood Ahmad
A comprehensive study of the manganese ore deposits of Banswara manganese belt (23°10′-23°20′N to 74°15′-74°25′E) in the Banswara district, Rajasthan, has shown a characteristic assemblage of manganese ore minerals. The manganese ore deposits are associated with Aravali phyllite, schist, quartzite and limestone, etc., and occur within a narrow linear belt trending NW-SE. These meta-sediments hosted

Comparative Analysis of Pixel and Object Based Classification Approach for Rapid Landslide Delineation with the Aid of Open Source Tools in Garhwal Himalaya J. Geol. Soc. India (IF 0.899) Pub Date : 2020-07-21 Harshita Asthana, Chandrashekhar A. Vishwakarma, Priyadarshini Singh, Pardeep Kumar, Vikas Rena, Saumitra Mukherjee
Landslides are the natural geomorphic processes that are essential for the landscape development. Loss of tremendous amount of life, natural resources as well as property has made this phenomenon a natural disaster. Number of researches have been done to understand this phenomenon and how to overcome this calamity with the aid of upcoming modern information services and technological advancements.
