This book presents in a concise format a simplified and coherent
geological-dynamical history of the Indian subcontinent (including
Sri Lanka, Bangladesh, Myanmar, Southern Tibet and Pakistan).
Encompassing a broad array of information related to structure and
tectonics, stratigraphy and palaeontology, sedimentation and
palaeogeography, petrology and geochemistry, geomorphology and
geophysics, it explores the geodynamic developments that took place
from the beginning around 3.4 billion years ago to the last about
5,000 years before present. Presented in a distilled form, the
observations and deductions of practitioners, this book is meant
for teachers, researchers and students of geology, geophysics and
geomorphology and practitioners of earth sciences. A comprehensive
list of references to original works provides guidance for those
seeking further details and who wish to examine selected problems
in depth. The book is illustrated with a wealth of maps, cross
sections and block diagrams - all simplified and redesigned.
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.

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.
