Resources
Minerals
China
clay is found in abundance in Thaliparamba and Kannur taluks of Kannur
district. Theses resources are not fully utilized in the district.
The
district is endowed with rich deposits of clay of which various types
are mined at many places for potteries, tiles and ceramic industries.
The most important areas where clay has been found are Pattuvam, Korom,
Perumba and Karivellore. Good quality kaolin occurs below the laterite
capping around Pilathara and Thaliparamba.
There are
a number of tile manufacturing centers along the coastal areas. Because
of the abundant availability of clay, there is great scope for
development of clay based industrial in the district.
Latterite
is quarried for bricks throughout the district on a small scale to meet
the local demand. Extensive quarrying is done in Kambil, kalyassery and
Cheruthazham areas.
Thin
horizons of lingnite are noted in the cliff sections at Kannur coast,
Pazhayangadi and Meenkunnu.
Beach
sands containing ilmenities, monazite, zircon, thorianite occur along
the coast, especially to the south of Valapattanam river mouth and near
Azhikode. Other minerals discovered recently are sillimanite near
Chandirukunnu, graphite near Payyavur, Manakadavu and minor bands of
iron ore near Cherukunnu Railway Station.
Many
occurances of bauxite deposits have been brought to light in the
district at Madayi, Korom, Payyavur and Pattuam near Thaliparamaba. They
may find use in the manufacture of refractories and cement as they are
not of high grade.
Limeshells
used for the manufacture of white cement and for industrial purposes are
found in the backwaters of Eranholi river, Dharmadam puzha, Anjarakandi
river around Thalassery and
Dharmadam as well as Valapattanam river in the east of Azhikkal ferry.
