Polycyclic Aromatic Hydrocarbons in Permian Coals of India: Source and Significance
Geological Society of India - Tập 94 - Trang 579-582 - 2019
Amiya Shankar Naik
The organic matter entrapped in the sediments often retain their molecular structures for millions of years. These structures hold important clues to the origin, precursors and proxies for the sedimentary environment. The investigation on the Permian coals reveal pyrene, benzo[a] anthracene, fluoranthene, indeno [1,2,3-cd] pyrene, chrysene, triphenylene, benzo[a] pyrene, benzo[e] pyrene, perylene,...... hiện toàn bộ
Heavy mineral distribution and characterisation of ilmenite of Kayamkulam — thothapally Barrier Island, southwest coast of India
Geological Society of India - Tập 81 - Trang 129-140 - 2013
Babu Nallusamy, Sinirani Babu, D. S. Suresh Babu
Mineral concentration and ilmenite characterization of the Thothapally — Kayamkulam Barrier Island of the southern Kerala has been studied. 96.86% concentrations of heavy minerals are recorded in the surficial and core samples (4 m) in the southern Kayamkulam and northern Thothapally areas. The total heavy mineral content decreases with depth. The primary heavy mineral suite of the surficial and c...... hiện toàn bộ
Deterministic and Probabilistic Seismic Hazard Analysis of Tindharia, Darjeeling Sikkim Himalaya, India
Geological Society of India - - 2022
G. N. S. Neharika Rao, D. Neelima Satyam
The simulation of appropriate ground motion is the main objective in earthquake-resistant designing to mitigate the impact of landslides and structural damages. The seismic hazard studies serve as the basis for quantifying the hazard associated within the particular area over a given time period. In this study, the detailed site specific hazard analysis of Tindharia site as well as Darjeeling Sikk...... hiện toàn bộ
Tunneling in lesser Himalaya, Jammu and Kashmir, India with special emphasis on tectonic mélange
Geological Society of India - Tập 88 - Trang 593-602 - 2016
Pratap Chandra Dhang
Himalayan fold belt has full of geological surprises, ‘mélange’ is one of them which create difficulties during tunneling. Such mélange completely went unnoticed during surface mapping and geotechnical investigation preceding the construction of the Udhampur railway tunnel (URT). During the construction, the mélange zone has encountered across the tunnel, which occurs along the Tanhal thrust (equi...... hiện toàn bộ
Seismic risk assessment at the proposed site of Gemsa wind power station, southwestern coast of Gulf of Suez, Egypt
Geological Society of India - - 2017

Facies Analysis, Markov Model and Linking of Sub-environments in the Early Permian Barakar Coal Measures of Godavari Gondwana Basin of Southeastern India
Geological Society of India - Tập 95 - Trang 599-608 - 2020
Zahid A. Khan, Ram Chandra Tewari, Rabindra Nath Hota
The early Permian Barakar coal measures Formation of Gondwana Supergroup in the Godavari basin comprise siliciclastic fluvial facies of passive continental margin. The lithofacies relationship and their sequences are analyzed quantitatively using embedded Markov Chain analysis along with improved binomial probability method. Summarized lithofacies sequence show the following order: (CGSD= Matrix s...... hiện toàn bộ
An Assessment of the Environmental Impact of Coal Mining through Acid Mine Drainage and Soil Degradation from Makum Coalfields, Upper Assam, India: A Case Study
Geological Society of India - Tập 99 - Trang 1113-1120 - 2023
Manish Kumar, Manish Kumar Srivastava, Kaushal Kishor, Alok K. Singh
Acid mine drainage and soil erosion are significant problems in the coal mining area. It affects the water quality and soil quality, henceforth affecting plant growth and most aquatic life. During the last two decades, coal mining areas were increased by 194 hectares in Makum coalfield (Assam), which led to an increase in acid mine drainage and soil loss. In this paper, the water chemistry of wate...... hiện toàn bộ

Groundwater modeling of Hiranyakeshi watershed of Ghataprabha sub-basin
Geological Society of India - Tập 90 - Trang 357-361 - 2017
Nagraj S. Patil, N. L. Chetan
Groundwater modeling is an effective tool for managing the groundwater resource and to predict for the future. There is a need for proper quantification of the scarce water resources that are under threat because of the population explosion, industrialization, urbanization and climate change. More than 60% of India is underlained by hard rock aquifers. The Hiranyakeshi watershed of Ghataprabha sub...... hiện toàn bộ
An Assessment of Alternate Fertilizer Potential of Glauconite Deposits in India using Simple Beneficiation Methods
Geological Society of India - - 2022
Tathagata Roy Choudhury, P. V. Sunder Raju, Tehreen Shaikh, Santanu Banerjee
This study presents an assessment of alternate fertilizer potential of glauconite deposits in India with precise stratigraphy, dimension of the deposit, and its K2O contents for understanding their alternate potash fertilizer potential. Further, it provides simple beneficiation methods to separate glauconite from the rest of the sediments. Many of the glauconite deposits, particularly those of Pre...... hiện toàn bộ
