Behavioural and Environmental Significance of the Rosetted trace Fossil Dactyloidites ottoi (Geinitz, 1849) from the Early Cretaceous (Berriasian) of Kachchh, Western India J. Geol. Soc. India (IF 1.3) Pub Date : 2023-08-14 Satish J. Patel, Apurva D. Shitole, Jehova L. Darngawn, Jaquilin K. Joseph
For decades, naming the rosetted trace fossil species of Dactyloidites ottoi or Haentzschelinia ottoi has been a matter of discussion. The phobotactic behaviour of the trace makers reflecting systematic mining to form branched radial elements converging at the central vertical shafts in both the ichnogenera are similar and foreknown. Berriasian marine deltaic deposits of the Jhuran Formation, India

Ascertaining Potential Causes of Hillslope Failure Associated to Human Settlement: A Case Study from Alaknanda Valley, Uttarakhand, NW Himalaya, India J. Geol. Soc. India (IF 1.3) Pub Date : 2023-08-14 Vipin Kumar, Yaspal Sundriyal, Neha Chauhan, Mohit Kumar Puniya, Sameeksha Kaushik, Sanjeev Kumar, Dhirendra Singh Bagri, Naresh Rana
Growing human population along the river valleys in hilly terrain particularly on the fluvial sediments poses increasing risk of terrace instability and subsequent failure. Such instability and failure result in frequent loss of settlement, agricultural lands, and often lives. Alaknanda River valley in Uttarakhand comprises many fluvial terrace slopes that accommodate human settlement and hence one

Impact Assessment of Road Construction on Landslide Susceptibility in Mountainous Region using GIS-Based Statistical Modelling J. Geol. Soc. India (IF 1.3) Pub Date : 2023-08-14 Amol Sharma, Chander Prakash
Landslide susceptibility is crucial for effective hazard management, planning mitigation, and risk reduction strategies. The present study assessed the impact of road construction on landslide susceptibility for the Mandi district. 1723 landslides data for Mandi district was compiled from the various sources with eleven causative factors. The eleven landslide causative factors were selected from numerous

Multi-collinearity Based Parameter Optimization and Comparison among Multi-criteria Decision Analysis to Map Groundwater Potential Zones J. Geol. Soc. India (IF 1.3) Pub Date : 2023-08-14 S. Venkatesh, S. Parimalarenganayaki
Zonation of groundwater potential is a vital technique for long-term water governance and urban planning, particularly in agrarian countries such as India. As a result, the present groundwater potential mapping study was carried out in Tiruvannamalai district, Tamil Nadu, India to assess the capability of the aquifer using 21 groundwater conditioning parameters. An overlay analysis was performed to

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 J. Geol. Soc. India (IF 1.3) Pub Date : 2023-08-14 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 water

Macroseismic Study of 4th January 2016, Manipur Earthquake, and its Implications J. Geol. Soc. India (IF 1.3) Pub Date : 2023-08-14 Harish Kumar, L. H. Moirangcha, W. S. Rocky, B. R. Syngai, E. Mohanraj, M. Mudi
An earthquake of magnitude 6.7 M (Latitude 24.834N; Longitude 93.656E) on the Richter scale rocked in the Noney area, Tamenglong district, Manipur on 4th January 2016. The shock was strongly felt in most parts of the Northeastern states of India viz. Manipur, Nagaland, Meghalaya, Assam, and its neighboring countries Myanmar and Bangladesh. Macroseismic study was conducted to assess the intensity of

Petro-geochemical Signatures as Evidences for Tectonic Setting, Palaeoweathering and Provenance of Eocene Kopili Sandstones, Meghalaya, Northeast India J. Geol. Soc. India (IF 1.3) Pub Date : 2023-07-06 Mouchumi Boruah, Nagendra Pandey
Spectacularly preserved yet least studied middle to late Eocene Kopili Formation in parts of East Jaintia Hills district, Meghalaya has been documented to understand the provenance, tectonic setting and palaeoweathering employing petrological and geochemical attributes. The Kopili Formation is characterized by alternations of fossiliferous marl-splintery grey to black shale-siltstone and fine to medium

Petrography, Diagenesis and Hydrocarbon Source Potential of the Barail and Disang Group of Rocks in Parts of the Naga Schuppen Belt and Inner Fold Belt of Assam-Arakan Basin J. Geol. Soc. India (IF 1.3) Pub Date : 2023-07-06 Manash Pratim Gogoi, Pradip Borgohain, Yadav Krishna Gogoi, Devojit Bezbaruah
Rock-thin section study, scanning electron microscopy (SEM), X-ray diffraction (XRD), and Rock-Eval pyrolysis have been carried out on the Barail (Oligocene) and Disang (Eocene) groups of rocks of the Naga Schuppen Belt of Assam-Arakan Basin to understand the reservoir properties and hydrocarbon source potential. Analyses show that the Barail Group sandstones are moderately well-sorted, medium-grained

Geochemistry of Jutogh Metasediments, Lesser Himachal Himalaya, India, and their Implications in Source Area Weathering, Provenance, and Tectonic Setting during Paleoproterozoic Nuna Assembly J. Geol. Soc. India (IF 1.3) Pub Date : 2023-07-06 Hifzurrahman, Pritam Nasipuri, Kumar Batuk Joshi
This paper reports the results of the geochemical study of the Jutogh metasedimentary rocks that occur as a tectonic window between the Lesser and the Higher Himalaya. The Jutogh Group of rocks are mostly mica-schists of different metamorphic grade. The weathering intensity parameters, such as chemical index of alteration (CIA), plagioclase index of alteration (PIA), and index of compositional variability
