INTRODUCTION South West Garo Hills came into existence as a district of the state of Meghalaya on 7th August 2012. It is a small district of just 822 sq km with only 1, 70,794 people.

1.1 A brief overview about the District:

State/Country Meghalaya/India Region South West Meghalaya Headquarters Ampati Inaugurated on 7 August 2012 CNRD Blocks 3 Area 822 sq kms. Population (2011) 1, 70,794 Coordinates 25°27.505, 089°56.456

1.2 District-Topography:

The District is bounded on the north by Selsella and Rongram Community and Rural Development Block; on the south by Sherpur and Jamalpur District of Bangladesh and Dalu and Gambegre Community and Rural Development Blocks on the east and on the west by Dhubri and Kurigram District of Assam and Bangladesh respectively. As a natural boundary, the district has the river Kalu (also known as Ganol) on the North and providing a long de- marcation line to Dhubri District and Selsella while the river Jinjiram flows along the western boundary of the district. Physically the area of the district extends upto the 11 kilometers short of Tura on the east; Mankachar on the north. The district has approximately 35 kilo- meters of international boundary with Bangladesh on the south and western side. Nearly one third of the total number of villages of the sub-division is declared as border villages by the Border Area Development Department. Nearly one third of the total area is said to be covered with hills. While the rest is, literally a plain region dotted with small hillocks here and there. A large and continuous strip of plain land stretches from Garobadha towards Mankachar extending upto Mahendraganj and Gopinath Killa along the border of Dhubri District of Assam and Bangladesh. The hill regions, on the other hand, begin from 11 kilometer short of Tura on the east and cover Damalgiri, Okkapara, Mellim and Salmanpara areas on the south. These hills and hill ranges occur in the east and southern parts of the District and gradually slope down to- wards north and west and ultimately converge with the bigger plain region.

OVERVIEW OF MINING ACTIVITY IN THE DISTRICT South West Garo Hills District plays the major role in the production of river sand where sand lifting/ mining takes place mainly from the river and few streams for use in all purposes. There are no sand mines or quarries in this District except rivers and streams. Ganol river being the main source for minor minerals like sand, bajari/aggregates. The lifting of sand is presently carried out from this river and its tributaries in the entire District. Important mineral occurrences are gypsum in Mahendraganj and Harigaon areas; ordinary clay/brick earth in the plain belts of the district in Damalgre, Mukdangra, Borolatri, Takuranbari, Jolgaon and Salmara-Mankachar areas. Gypsum occurs as veins and is primarily used as a finish for walls and ceilings, wall board, sheetrock and in concrete blocks in build- ing construction. It is also used as fertilizer and soil conditioner, adding hardness to water and Portland cement.

PROCESS OF DEPOSITION OF SEDIMENTS IN THE RIVERS OF THE DISTRICT The mining areas of Boulder/Sand/Bajari are presently confined to river courses. Since all the rivers are originating from hills and passing through hilly terrain running down- stream to approach the plains, the accumulation of Boulder, Sand and Bajari etc. on the riv- er beds occur by natural phenomenon. During rainy season, high runoff along the rivers and its tributaries causes transportation and deposition of huge quantity of sediments all along the river course. There is a regular flow of water which carries sand particles, sediments and gets deposited in the river basin on a regular basis Owing to the geological set up of the South West District including areas under the jurisdiction of West and South West Division, huge accumulation of river sediments (boul- der, sand, bajari and clay) offers good opportunity of environmental friendly mining activi- ties of minor minerals in the District. Sand is replenishable. Due to sparce rainfall over the last few years the river flows to an average height but flows to its maximum height only during and just after monsoon sea- son. Mining of Building Grade sand from the river bed will not have any impact on the ground water body in the area. During heavy rains the flood waters overflow the bank and inundate the fields and dry regions. The floods have its own ways of depositing sand not on- ly at the bank but also on the dry surface region. Added to the deposition of sand on the riv- er basin by stratification through lateral deposition of sands on the land surface is by Differ- ential Lateral Deposition (DLD). The later grade is coarse, medium and fine sand to mud and soil beyond. In this soil, agricultural operation goes on from the bank to the cultivated land surface. The yearly deposition of sand is by natural filling during flood season with slight var- iation depending upon the amount of river flow, the quantity of water flowing and the amount of sand load carried during the river flow.

RAINFALL: MONTH-WISE The climate of Meghalaya varies with the altitude. The climate of South West Garo Hills District being plain belt region is warm and humid, except in winter. True to its name, the Meghalaya sky seldom remains free of clouds. The average annual rainfall is about 1,150 cm. Flood affected areas are mostly on the low altitude areas, bordering Assam and the international border (India-Bangladesh). Flash floods have become a regular feature in these areas, due to massive deforestation, unchecked jhum cultivation. The flood water carries huge amount of hill sand, stone, logs and trees, which are deposited in agricultural fields due to inundation of banks in the foot hills, thus causing immense damage to crops. The key to the health of the farm sector in the state lies in the health of the forest cover in the state. Every peak, every square inch of the upper range of the hills need to be under mixed forest cover to protect the soil from leaching and erosion to help regulate and decrease the fury of streams and rivulets during the monsoon season. Vegetation also help to retain soil moisture and ooze it out during the lean winter months to balance vegetative stress caused by mono cropping in the valley; to bestow vari- ous other advantage to help maintain the fragile eco-balance. This will ensure continuous cultivation of crops in the farm sector.

DISTRICT SURVEY REPORT (SAND/RIVERBED MINING) – SOUTH WEST GARO HILLS Page 19

Basement Complex of AMGC is represented by migmatite, banded gneiss, amphibol gneiss biotite gneiss with intrusive grey and pink homophaneous and porphyritic granite. The basement rock has pervasive metamorphic foliation striking NW-SE direction dipping 500 towards NE and bears signatures affected by ductile shearing. Banded migmatite gneiss is of granitic composition and exhibit compositional bandings defined by leucosome and me- lasome layers. The gneiss has undergone high grade metamorphism from upper amphibo- litesfacies to granulite facies condition.

Dykes of ultrabasic and basic rocks occur as intrusive into the AMGC and the Gond- wana Group. Most of the dykes trends along NW-SE direction and are exposed along the Baghmara-Singrimari Road. Euhedral crystal of olivine and pyroxene are seen the dyke rocks. Pegmatite with coarse grained quartz aand K-felspar occurs as veins and apophyses within the AMGC. Unique assemblage of Gondwana rocks represented by Talchir and Karharbari For- mation are exposed in the western part of the area,near Singrimari (C.S.Fox,1934). The Tal- chir Formation is represented by greenish glauconitic fine grained sandstone and Karharbari Formation is represented by very coarse grained felldspathic sandstone. There are reports of coal-bearing horizons within the Gondwana sequence, for which GSI is actively carrying out exploration in the alluvial covers of the Brahmaputra River. AMGC at many places is capped by conglomerate horizon followed by sandstone and shale of the Jaintia Group, represented by the Sylhet/Tura Sandstone Formation followed upward by the Kopili Formations. The Garo Group is represented by Baghmara and Chengapara Formation and exposes erratically. The Tertiary sequence has gentle dip of 5*- 10* towards SW striking NW-SE direction. Thin coal seams that are found within the Shel- la/Tura Sandstone formation are being mined locally at places. Occurence of lignite from West Garo Hills District is being reported for the first time by GSI. The oldest rocks in South West Garo Hills are represented by Mylliem granitoid of Neo- proterozoic to Early Palaeozoic age which is grey/pink in colour and porphyritic in nature. The sedimentary rocks of Tertiary age overlie Mylliem granitoid. The Shella Formation of Jaintia Group consists of sandstone, lithomargic clay, shale and some coal seams followed by Kopili Formation which is an alternate sequence of shale and sandstone with phosphatic nodules at places. Kopilli Formation is overlain by Baghmara Formation of Garo Group of Miocene Age which consists of conglomerate, siltstone and sandstone followed by Changpara Formation of coarse sandstone, siltstone, mudstone and marl. Garo Group is overlain by Dupitila Group having brown clay and sand, siltstone, grit, conglomerate and sandstones. Undifferentiated quaternary sediments are characterised by undifferentiated sand, silt and clay. Sorbhog Formation of Older Alluvium of Recent Age comprises of oxi- dised to feebly oxidised brown sand, silt and clay while the Newer Alluvium consists of un- stabilised and unoxidized sand, silt, clay and pebbles. Yamuna faults and Dapsi faults have been established in the area. Table-II provides a glimpse of the Geology that is observed in the proposed mining

In Garo Hills the granite has been metamorphosed into granite gneiss. The lower Gondwana rocks of permo-carboniferous age are recognized in the western and south western part of Garo Hills. It consists of pebble beds, sandstone (Tura) and carbonaceous shade. Recent alluvium is found in the western & south western part of the Garo Hills along the foothills. This alluvium consists of fine silty sand and light to dark grayish shale & clay with pockets of coarse sand.

11.1 MINERALS OF SOUTH WEST GARO HILLS DISTRICT Few deposits of limestone, coal, granite, granite gneiss, clay and construction miner- als and rocks occur along the south western border with Bangladesh. Coal had been found as early as 1815 by the British when it was used only as domestic fuel by the locals. Uses of Limestone:- By burning it in kilns limestone had been used as quick lime (calcium oxide) slake lime (calcium hydroxide) however the main use is in the manufacture of cement and mortar mixed with coal and other aggregates, pulverized limestone is also used to neu- tralized acidic soil and Acidic mine Discharges as experimented by the chemists of DMR in the East Jaintia Hills District. The crushed aggregate is also used for road construction, build- ings and asphalt concrete etc. Metamorphosed limestone or dolomite can be used as slabs like marble. Uses of Granite:-Granite is mainly used for construction of bridges, buildings, paving roads and paths and monuments. Polished granite is used as counter tops, table tops as tiles on the floor, stain treads and many design constructions. Uses of Coal:- Besides used as fuel, coal at present is used for Electicity Generation in the plain areas where hydro power is unavailable. In the steel factories coalis used in the pro- duction. Cement plants also require coal for energy production. When mixed with water and gravel and sand, it forms a sort of useful concrete. However main usage is power genera- tion. Gravel

Gravel is a loose aggregation of rock fragments. Gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments. Gravel is catego- rized into granular gravel (2 to 4 mm or 0.079 to 0.157 in) and pebble gravel (4 to 64 mm or 0.2 to 2.5 in). ISO 14688 grades gravels as fine, medium, and coarse with ranges 2 mm to 6.3 mm to 20 mm to 63 mm.

DISTRICT SURVEY REPORT (SAND/RIVERBED MINING) – SOUTH WEST GARO HILLS Page 21

The granitic gneiss are extensively quarried for road metal, fencing blocks and build- ing stones. Apart from this, Roughstone are used for the manufacturing of M-Sand and cursher products like, Jelly of various sizes, dust etc. Brick Earth

Bricks are the most commonly used construction material. Bricks are prepared by moulding clay in rectangular blocks of uniform size and then drying and burning these blocks. In South West Garo Hills District, brick clay occurs in the wetlands/paddy fields in the lowlands and midlands.

Gypsum Primarily used as a finish for walls and ceilings, wall board, sheetrock. Used in con- crete blocks in building construction. Also used as fertilizer and soil conditioner, adding hardness to water and Portland cement. It occurs as veins in Mahendraganj and Harigaon areas of the district.
