The active tectonic setting of the Himalayan continental collision zone gives rise to the variety
of rock types and heterogeneity in the topography of Himachal Pradesh. Complex plate
movement and differential deformations produce high-grade metamorphic rocks containing
anisotropy with or without loss of cohesion. Because the region is a crucial economic and
strategic zone in terms of defense it becomes important to track the conditions of transportation
lifelines due to natural and anthropogenic phenomena. NH 05 is one of those cardinal lifelines
that joins the Indo-China international border with central and eastern India. Seismic activity
is common in the region and landslides are in the day-to-day news, especially during the period
of monsoon. This represents serious instability in the study area and needs to be examined
properly by using the most reliable methods of slope stability. Characterization of rock by using
Geomechanical classification is one of the best ways to visualize actual rock failure in the
future and it can suggest us the remedial measures to stabilize the slope. For that purpose,
potential roadcut locations of failure were chosen from NH 05 and geometrical and
Geomechanical parameters have collected from the field. Kinematics analysis of joints and
slope data confirms the types of failure and then characterization based on QSlope, Rock Mass
Rating (RMR), Slope Mass Rating (SMR), and Continuous Slope Mass Rating (CSMR) clear
the geotechnical condition of the region. Many slopes having multiple types of failure shows a
high potential to fail, along with that some slopes are found to be of good stability. The remedial
measure has been suggested according to the findings, which can serve better communication
and contribute safe lifeline system in the region.

Research Papers Paleo-environmental study of the Raniganj and Barakar Formations: Implications from the Geochemical and Geomechanical Aspects of Sandstone and Shale
May 9, 2022 - J GSI ( Journal of Geological Society of India)
Uniaxial compressive strength (UCS) is the most fundamental physic-mechanical parameter that is primarily required in any geotechnical and geological engineering projects. The dependence of strength of primary rocks on the alteration indices have been previously studied, but it is unknown for secondary/ sedimentary rocks. Therefore, in this paper, Lower Gondwana coal measure rocks (sandstone and shale) have been studied geochemically and geomechanically. The provenance, paleodepositional environment, tectonic setting, palaeoclimate, and UCS of the Barakar and Raniganj coal measure rocks have been assessed. The study revealed that an arid, non-marine and deltaic depositional environment prevailed during the sedimentation of Barakar and Raniganj Formations. The provenance was deduced to be mafic igneous. It was also deduced that the Lower Gondwana sandstone is clay rich, and the sandstone and shale cannot be classified using the chemical classification scheme for terrigenous clastic sediments. The dependence of UCS on the weathering indices have been evaluated and a positive relationship was obtained.

This expresses the essence of democratic living and reinforces the need for selfless service, appreciation of the other man's point of view, and consideration for fellow human beings. The overall goal of the NSS, as originally envisioned, is service to the community through personal development opportunities provided while enrolled in an educational institution.
