Geology
Most of
the area is covered by the unconsolidated sediments of Quaternary age except in
the northwestern part, where isolated patches of Archaen Crystallines and
Tertiary sandstone are exposed. The Archaeans are mainly represented by the
Charnockite Group of rocks comprising garnetiferrous granulite and the
Khondalite Group of rocks made up of quartzite of genesses.
The
Tertiary sandstone (Cuddalore Formation) comprise pinkish, yellowish, reddish
(variegated colours) medium to coarse grained sandstone and clay stone. It is
overlain by thin alluvium and exposed towards north of Vaigai River. Detached
exposures of laterite and lateritic soil are seen in the northwestern part of
the district.
A major
part of the district is covered with the fluvial, fuvio-marine, Aeolian and
marine sediments of Quaternary age. The fluvial deposits which are made up of
sand, silt and clay in varying degree of admixture occur along the active
channels of Vaigai, Gundar, Manimuthar and Pambar rivers. They have been categorized
into levee, flood basin, channel bar/ point bar and paleo-channel deposits. The
paleo channel deposits comprise brown coloured, fine to medium sands with well-preserved
cross-beddings.
The
fluvio-marine deposits are exposed in the Vaigai delta as deltaic plain,
paleo-tidal and dune flat deposits. The deltaic plain and dune flats comprise
medium, grey brown sands. The paleo tidal flat deposits include black silty
clay, black clay and mud. In Rameswaram Island, the fluvio-marine deposits
include indurated sand and dune sands.
The
Aeolian deposits comprise red sands which are in nature of ancient dunes and
occur over a 3.2 km wide and 8 km long stretch and lie parallel to
the sea coast. These are separated by marshy deposits of black clays. The sands
are underlain by calcareous hardpan. In Rameswaram Island also brown sand
deposits occur around Sambaimadam on either side of NH 49 west of the town.
The
marine formation comprises coastal plain deposits of sand and clay in varied
proportion. Marine calcareous hardpan occurs as low terraces and platforms,
with admixture of quartz, limonite and garnet concentration.

Gulf of Mannar Marine Biosphere Reserve:
Marine
Biosphere Reserve not only in India, but also in south and Southeast Asia. The
IUCN Commission on National Parks and WWF, identified the Reserve as being an
area of” “Particulars concern” given its diversity and special multiple- use
management status. In addition, as the first marine biosphere reserve declared
in India, this area has long been a national priority.
The Gulf
of Mannar and its 3,600 Species of flora and fauna is one of the biologically
richest coastal regions in the entire mainland of India. It is equally rich in
sea-algae, sea grasses, coral reef pearl banks, fin & shell fish resources,
mangroves, and endemic & endangered species. It is an important habitat for
the highly endangered sea mammal, the dugong commonly called the sea cow.
There
are 137 species of coral found in Gulf of Mannar. The coral come in myriads of
shapes. Some have finger like branches and others dome-shaped colony with a network
of ridges and furrows. Sponges, although at casual glance look like plants, are
animals, living singly or in colonies of many individuals. Their colours vary
as much as shape, being green, red, yellow, and even black or white. In the
crevices, these sponges are found with many animals, ranging from tiny crabs
and brittle star to bivalve mollusks. 275 species under 8 orders are found in
Gulf of Mannar.
