The Quaternary sediments in Gujarat represent three depositional envir
onments-marine, fluvial and aeolian. The interplay of palaeoclimatic a
nd glacio-eustasy factors controlled the shaping of the landscape of G
ujarat during the Quaternary period. The landforms are broadly divisib
le into three geomorphic units. The Rann of Kachchh represents filled-
up Holocene gulfs, the sediments having accumulated in estuarine-cum-d
elta environments affected by sea-level fluctuations. The Gujarat coas
tline is characterized by variation in trend, shoreline features, offs
hore conditions and sediment nature, pointing to various controlling f
actors like tectonic framework, eustatic sea-level changes, and climat
e-related aeolian, fluvial and marine processes. The alluvial plains o
f Central and North Gujarat are made up of thick Quaternary continenta
l deposits of fluvio-marine, fluvial and aeolian origin. Showing recor
d of sea-level fluctuations and climatic variation, these deposits occ
upy the structural depressions related to continental margin rifting a
nd graben formation (Narmada and Cambay). The Lower Pleistocene, still
a 'grey area' for age data are not available.
