Minerals in Meghalaya

Meghalaya is endowed with sizeable deposits of a number of valuable minerals. Coal, limestone, uranium, granite, kaolin, clay and glass sand are the principal minerals. A brief account of mineral resources is as follows:

Limestone

An extensive bed of limestone occurs in the Southern part of the State from Jaintia Hills in the East and Garo Hills in the West. The main deposits are found around Cherrapunjee, Mawlong, Ichamati, Shella, Komorrah in the East Khasi Hills district; Borsora and Bagli in the West Khasi Hills district; Lakadong, Lumshnong and Nongkhlieh in the Jaintia Hills district; and Darrang Era-aning, Siju, Chokpot in the South Garo Hills district.

Coal

Most of the coal reserves in Meghalaya are tertiary reserves.Coal occurs in Mikir Hills, Khasi Hills, Jaintia Hills and Garo Hills districts. The production of upgraded coal was reported by private non-captive mines in the unorganised sector located in these areas except Mikir Hills district. The mines are operated mostly by the local tribals in their private lands.

Uranium reserves in Meghalaya

Meghalaya is the third uranium rich state in the country after Jharkhand and Andhra Pradesh. The state accounts for 16 per cent of Indias uranium reserves, with deposits estimated to be around 9,500 tones and 4,000 tones respectively at Domiasiat and Wakhyn, both in West Khasi hills region.

Kyelleng-Pyndengsohiong, Mawthabah (KPM) uranium mining project is located in the West Khasi Hills district of Meghalaya state in the North East region of India. Formerly this project was also known as Domiasiat uranium mining project. The Atomic Mineral Directorate for Exploration and Research in 1972 found evidences of uranium deposits in the area which was confirmed by 1996 after intensive drilling between 1992 and 1996. Uranium Corporation of India Limited (UCIL) proposes to mine it using open pit mining method up to a depth of 45 m. The processing plant will be constructed at Mawthabah. It is estimated that KPM deposit in Meghalaya will last for 25 years.

Clay

Clay of various types such as Kaolin (China clay), white clay, and fire clay are found in various parts of the states. These clay are suitable for the ceramic, paper, rubber and refractory industries. It has been estimated that there are a few hundred million tonnes of clay reserved in the state.

Granite reserves

Deposits of multi-coloured granite have been located around nongpoh in the Ri-Bhoi district, mylliem in the east khasi hills district; mawkyrwat and nongstoin in the west khasi hills distric.

Sand deposits

The sand deposits of the State are mainly concentrated in Khasi hills. The glass deposits of Laitryn grew coal field and around Shillong are found to be suitable for manufacturing of ordinary bottle glasrs, window glass etc. and with some chemical pu rification even for sheet glass and flint glass. Some of the sands are within the specifica tion o f foundry sands, which are now in great demand in the country. The estimated reserve of glass deposits is about 2.30 m illion tonnes as against Tripura – 0.18 m illion tones.

Feldspar and quartz occur near Tura in Garo hills and near Hahim in Khasi Hills. The estimated mining reserve of feldspar in the State (0.02 million tonnes) is at par with Assam (0.02 million tonne),2 3456 while the quartz is 2.03 m illion tonnes as compared to Tripura – 0.19 million tonnes.

Massive sillimanite associated with corrundum occurs in Khasi hills . More than 2i deposits have been located in the vicinity of Sonapahar, Nongpur and Nongbain villages and are worked by the Assam Sillimanite Ltd. Most of the deposits contain sillimanite with admixed corrundum to a little extent, one or two entirely of corrundum and several of sillimanite only.

Meghalaya Human Development Index

The State of Meghalaya is situated on the north east of India. It extends for about 300 kilometres in length and about 100 kilometres in breadth. It is bounded on the north by Goalpara, KamrupandNowgong districts, on the east by KarbiAnglong and North Cachar Hills districts, all of Assam, and on the south and west by Bangladesh.

Meghalaya is subject to vagaries of the monsoon. The average annual rainfall is about 2600 mm over western Meghalaya, between 2500 to 3000 mm over northern Meghalaya and about 4000 mm over south-eastern Meghalaya. There is a great variation of rainfall over central and southern Meghalaya. Meghalaya Human Development Index

Meghalaya is basically an Agricultural State with about 80% of its total population depending entirely on Agriculture for their livelihood. Rainfall varies from place to place and from altitude to altitude. The amount of rainfall over Cherrapunjee and Mawsynram is quite heavy. During the last two decades, it has ranged from 11,995 mm to 14,189 mm in Cherrapunjee and over Mawsynram it was 10,689 mm to 13,802 mm.

HUMAN DEVELOPMENT INDEX:-

The Human Development Index (HDI) is a comparative measure of quality of life. It mainly comprise three components:-

A long and healthy life: Life expectancy at birth.
Education index: Mean years of schooling and Expected years of schooling.
A decent standard of living: GNI per capita (PPP US$)for countries worldwide. It is a standard means of measuring well-being, especially child welfare.
It is used to distinguish whether the country is a developed, a developing or an under-developed country, and also to measure the impact of economic policies on quality of life.

According to Global Hunger Index – 2017, only 9.6 per cent of our children, between 6 and 23 months of age, receive adequate diet and 97 million children in India are underweight! Thus Indian economy is going to face a gigantic problem of unhealthy and unskilled work-force in the future, which will further degrade our resources into liabilities. Ironically, according to a study, two-thirds of food to feed 600 million poor Indians is lost as hungry millions do not have enough purchasing power to buy the same. Now, government itself can buy it from farmers with minimum support price (MSP). It will certainly stop the incidence of farmers’ suicides. The excess food can then be distributed to students in addition to the midday meal. This will attract more students to school and address the issues like illiteracy, school dropout, child labour, hunger and malnutrition.

In the Human Development Index (HDI) of India for the year 2011, Meghalaya is ranked 26th with 0.585(Medium) HDI value.

Measures of HDI indicators for Meghalaya:-

Mizoram per capita income in 2009-10:- Rs 35,323,
Literacy according 2011 census :-84% (24^th rank),the male literacy rate is 77.2 per cent and the female literacy rate is 73.8 per cent. In 2011-12, the state had a total of 43,102 teachers in lower primary & upper primary schools, 4,621 teachers in secondary schools and 526 teachers in higher secondary schools.
Education index of Meghalaya :- 0.512,(28^th rank).

Meghalaya, among the eight North Eastern States, is ranked 7th, only above Assam which has 0.534 HDI value in 2011.
Meghalaya’s first HDI report “Meghalaya Human Development Report 2008” was published in 2009, and has been the sole report since to indicate the health of the State to the world.The report clearly indicated that the rate of development in Meghalaya is slower than in most of the state and hence, been lagging behind while many states have improved their ranking.
The report highlighted that the health sector is poor and East Khasi Hills tops in HDI and GDI among the districts followed by West Garo Hills.
The report seemed to highlight Meghalaya being significantly behind in almost all sectors in comparison all other states while it failed to furnish full details, which could make it possible to make better comparisons.
Even then, a new report is yet to be furnished.

Relief and structure of Meghalaya

Relief and structure of Meghalaya

Meghalaya is an upland area formed by a detached block of the Deccan plateau. Its summits vary in elevation from 4,000 to 6,000 feet (1,220 to 1,830 metres). The Garo Hills in the west rise abruptly from the Brahmaputra River valley to about 1,000 feet (300 metres) and then merge with the Khasi Hills and Jaintia Hills, adjacent highland systems that form a single massif of tablelands separated by a series of eastward-trending ridges. The southern faces of the plateau, overlooking the Bangladesh lowlands, is particularly steep.

Meghalaya Plateau belongs to the part of Super Continent of Gondwanaland, i.e., the Peninsular table land, but is detached from the latter by the intervening spread of the alluvium of the Ganga and the Brahmaputra. The structural history of the region reveals several phases of erosion, sedimentation, diastrophism, intrusion, movements of land and sea, and emission.

The plateau is mainly made up of rocks of the pre-Cambrian age. The pre-Tertiary and Tertiary rocks occur above these rocks on its western and southern margins. Stratigraphically the rocks of the plateau belong to five broad geological formations, namely the Archaean gneissic complex, the Shillong group of rocks, the lower Gondwana, the Sylhet traps, and Cretaceous – Tertiary – Quarternary Sediment.

The Archaean-gneissic complex occupies the central and northern parts of Meghalaya Plateau. The rocks include gneiss, granite, quartzites, schists, etc. The Shillong group of rocks lying unconformably over the gneissic complex, occurs in the central and eastern parts of the plateau These include phylite, quartzites, schists and conglomerates.

The lower Gondwana rocks are found in the western part of Garo Hills which include pebble beds, sandstones and shale. The Sylhet trap is exposed along the southern border of the Khasi Hills in an east-west direction, and rests unconformably over the eroded pre-Cambrian basement rocks. These rocks are predominantly basalt, rhyolite and acid tuffs.

The Garo Hills region of the State, in its greater portion, is formed of gneissic rocks overlaid by sandstones and 1 conglomerates of Cretaceous-Tertiary system.

The sediments of this system of rocks are known as the Garo group in the region. This group of rocks is again divided into the Simsang, Baghmara and the Chengapara formations. The Simsang is the oldest formation in the Garo group which lies conformably over the Kopili series (the youngest formation of the Jaintia group of Cretaceous – Tertiary sediments), and consists of siitstone and sandstone.

the Baghmara formation includes sand, pebble, conglomerates and clay which lie conformably over the Simsang formation. The Chengapara formation consists of sand, siitstone and clay. On the top of these Cretaceous-Tertiary formations rests limestone of Numulitic age, while sandstones of upper Tertiary origin form low hiiis along the Mymensing border. Relief and structure of Meghalaya

The Khasi Hills are located east of the Garo Hills. The other Khasi tribes did not have princes but their twenty petty states (hima), and sometimes even smaller tribal divisions, are led by one or two Chiefs -selected in various ways- usually styled Siem, Syiem. The names of these chieftainships are : Bhawal, Cherra (or Sohra; capital Cherrapunji), Dwara (capital Hat Dwara), Jirang, Khyri(e)m (capital Cherrapunjee, under a Radja), Langrin, Lungiong, Maharam, Malai Sohmat, Marriw, Mawdon, Mawiang, Mawlong, Mawphlang, Mylliem (including Shillong city, the colonial capital of all Tribal Assam), Nobosohphoh, Noglwai, Nongkhlaw, Nongspung, Nongstoin, Pamsanggut, Rambrai, Shella, Sohiong. or Sardar .

The Jaintia Hills are located further to the east from the Khasi Hills. The twelve Chiefs of the elaka (tribal province) of the Jaintia, a Khasi subtribe of the) Pantars = Syntengs tribes, are styled Dolloi, and the land is called after them in Khasi: KA RI KHADAR DOLLOI ‘Land of 12 Tribal Chiefs‘) – they are in Nartiang itself (see the Raja, uniquely also styled, as premier Chief: U Kongsong), and in Amwi, Jowai, Lakadong, Mynso, Nongbah, Nongjngi, Nongphyllut, Nongtallang, Raliang, Shangpung, Sutnga (see below; also cited as seat of a Syiem) Above them is the only true princely ruler of the area, the Raja of Jaintiapur.

His winter capital is now in Bangladesh, with his summer residence shifted from Sutnga (where the family started as Syiems) to Nartiang; also a palace in the commercial center Borghat. The Jaintia Hills used to be a part of the Jaintia Hills District. The district has been bifurcated into two separate districts,namely, East Jaintia Hills and West Jaintia Hills on 31 July 2012.
