An erudite work on tectonic resurgence in Late Quaternary time of the Indian subcontinent embracing India, Pakistan, Nepal, Bhutan, and Bangladesh, Neotectonism in the Indian Subcontinent dwells on the causes and consequences of tectonic events that fashioned the landscape of a land characterized by a fragmented framework. The narratives on the structural and geomorphic developments during the morphogenic phase of the geodynamic history of the Indian subcontinent explain many phenomena. These include the tremendous height and spectacular structural-geomorphic architecture of the Himalaya, and the behaviour of wayward rivers in the sinking and rising Indo-Gangetic Plains. In addition are the shifting, deflection, piracy, and even disappearance of rivers and streams in the dry desertic terrane of western India, as well as the unique drainage pattern of the ruptured and rifted plateaus and coastal belts of Peninsular India. The formation of huge lakes due to river ponding in the stable continental shield in Karnataka is also explained. All of these phenomena are accompanied by profuse illustrations.
Neotectonism in the Indian Subcontinent portrays the evolution of the extraordinary landforms and landscapes of the subcontinent, constituted by multiple terranes of contrasted lithostructural architecture and distinctive geomorphic layout-each with an altogether different geological history. It chronicles events of crustal unrest or tectonic turmoil manifested as displacement, subsidence, and uplift of the ground with bizarre drainage changes and episodic seismicity. This book caters to planners, engineers, and hazard managers, but also satisfies the curiosity of those who are interested in understanding the formation of the Indian subcontinent.
Identifies areas and belts recurrently ravaged by geological hazards resulting from neotectonic activities Provides a wealth of information on neotectonic movements and consequent modification of landscape, drainage aberrations, and ground vulnerability, including references that also provide additional resources for those who seek to pursue comprehensive investigations Includes much new observation and refreshing interpretation to explain many of the striking landforms of the region2 388 kr

This book portrays the Himalayan-born River Saraswati, a legendary river that was the lifeline of a progressive and vibrant society for more than three thousand years. Written in simple language and richly illustrated, it highlights the events that resulted in the robbing of the Saraswati of its water and the end of a wonderful culture. The author weaves a geological narrative out of a mass of data generated by explorers, archaeologists, sedimentologists, geohydrologist, seismologists and remote-sensing specialists. The story explains how a great Himalayan river disappeared and how the Harappan Civilization vanished from the banks of the river Saraswati more than three and half thousand years ago in the wake of tectonic upheavals in the foothills of the Himalaya at a time when the rainfall had drastically declined. And it reveals that nowadays the Saraswati is an extraordinary wide water-less channel coursing through the vast but dry floodplain in western India.
