Thirumeni Stone Crushers Pre-feasibility Report Accessibility: This granite building stone quarry is located at 1.12km from the Thirumeni Village in Thaliparamba Taluk, which is located at about 42km S of Kannur District. The quarry can be reached via Cherupuzha-Muthuvom road. The location of this mining area is shown on the Administrative and key plan enclosed Vide Plate No -1 and 1A and Infrastructure Plan vide Plate No. 11. Topography: The lease is located on the slope of the hillock gently dipping towards West The highest elevation in this area is 405.0mRL and the lowest elevation is 340.0mRL. Brief Description of the Project: Geology: Regional Geology: The district can be broadly divided into seven geological belts trending NW-SE viz., (i) northern belt of Charnockite group extending further north and east to the adjacent districts, (ii) north central belt of Wayanad schist complex, (iii) Central belt of Peninsular Gneissic Complex extending to the southeast, (iv) south central belt of Vengad Group, equivalent to Dharwars, (v) southernmost belt of Migmatite Complex which extends further south to the adjacent district, (vi) Sedimentary (Warkalli Beds) in the western part near the coast and (vii) Quaternary sediments along the coast. The lithology of Kannur district is grouped under Precambrian, late Tertiary and Quaternary periods and the Precambrian rocks dominate over the other two. Charnockite Group, includes pyroxene granulite, charnockite (hypersthene granulite) and hornblende-diopside granulite. While hornblende granite and charnockite occupy large areas, pyroxene granulite occurs as linear bodies in the southeast. Hornblendebiotite gneiss constitutes the litho unit of Migmatite Complex. It has a large areal extent along the coast, south of Kannur. Towards east and southeast, discrete metasedimentary and ultramafic sequences which have been designaed as Wayanad Schist Complex and are considered equivalent of Sargur Group of Karnataka. They occur as isolated bands within charnockite and gneiss. Their contacts are generally discordant due to later folding, metamorphism and migmatisation. The group comprises quartzite, magnetite quartzite, garnet- kyanite-sillimanite gneiss, quart-mica-kyanite schist, quartz-sericite schist, amphibolite, kyanite- sillimanite-sericite quartzite, metaultramafites. Garnetkyanite- sillimanite gneiss/schist is widespread in the east, whereas the other members of Wayanad Complex occur as linear bands, lensoidal bodies and vestiges to the West Peninsular Gneisic Complex, represented by hornblende- biotite gneiss comprise of a complex suite of gneisses and granites, representing the anatectic phase of migmatisation of schist complex. East of Kannur extending upto Tellichery in the south, ..2 Granite Building Stone Quarry of M/s. Thirumeni Stone Crushers Pre-feasibility Report a large body of quartz-mica schist is separated from the other schistose rocks by a conglomerate horizon extending over 8km. This lithounit known as Vengad Formation, characterised by lack of migmatisation, presence of primary structres and absence of high grade minerals, is correlatable with rocks of Dharwar Super Group. Large bodies of anortjosite, gabbro, granite and granophyre from the post Vengad basic and acid intrusives. Dolerite dykes trending NW-SE represent the younger basic intrusives. Late Tertiary sedimentary rocks (Warkalli beds) occur as isolated patches along the coast near Kannur, Pazhayangadi and east of Payyannur. They comprise variegated clays and friable sandstone. At Kannur and Pazhayangadi, carbonaceous clay with thin seams of lignite is reported towards bottom of the sedimentary sequence. The Tertiaries as well as the basement rocks are extensively lateritised. The pebble bed, reported near Valapatnam along the bank of Valapatanam river, is considered to be of Quaternary age. Quaternary alluvial deposit occur along the coast and in the valleys. They constitute palaeo-marine deposit (Guruvayur Formation), fluvial deposit (Periyar Formation) of Valapatnam and Dharmadom rivers, fluvio-marine deposits (Viyyam Formation). Local Geology: The most of the part of area is covered with top soil of about 0 to 0.5m thickness, where as granites are very well exposed in the old working pit. A geological plan showing the granites and soil cover and the geological sections showing subsurface geology is prepared on 1:1000 scale and enclosed vide Plate No 4.
