Polycyclic Aromatic Hydrocarbons in Permian Coals of India: Source and Significance
Geological Society of India - Tập 94 - Trang 579-582 - 2019
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,...
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
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...
Deterministic and Probabilistic Seismic Hazard Analysis of Tindharia, Darjeeling Sikkim Himalaya, India
Geological Society of India - - 2022
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...
Tunneling in lesser Himalaya, Jammu and Kashmir, India with special emphasis on tectonic mélange
Geological Society of India - Tập 88 - Trang 593-602 - 2016
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...
Seismic risk assessment at the proposed site of Gemsa wind power station, southwestern coast of Gulf of Suez, Egypt

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
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...
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
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...
Tertiary Coal and Lignite Deposits of India and their Source Rock Potential: A Review on the Contribution of the Indian Coal Petrologists

Groundwater modeling of Hiranyakeshi watershed of Ghataprabha sub-basin
Geological Society of India - Tập 90 - Trang 357-361 - 2017
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...
An Assessment of Alternate Fertilizer Potential of Glauconite Deposits in India using Simple Beneficiation Methods
Geological Society of India - - 2022
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...
