Enquiries were then made, which resulted in the discovery of the spot where the shikari had picked up the stone, and for some time, until guards were posted near the locality by the Maharajah of Kashmir, in whose territory it lies, large quantities of the stones were brought to Simla and sold at absurdly low prices, the Laholis only asking about one rupee per seer for them. Various stories are told of the original discovery according to one of these, which was told me on the spot, a certain shikari, having lost the flint from his gun while out hunting, or, as is the custom of the natives when in want of a light for their pipes, looking for a handy fragment of quartz or other hard rock to strike a light with, picked up a small sapphire, and finding that it answered his purpose better than the ordinary fragments of quartz he was in the habit of using, carried it about with him for some time, and eventually sold it to a Laholi trader, by whom it was taken to Simla, where its value was recognised. The existence of sapphires in considerable quantities in some part of the North-West Himalayas was first brought to light in 1881, or early in 1882, when some were brought into Simla by traders from Lahol, who stated that they had been obtained from a spot among the mountains on the borders of Zanskar, where a landslip had laid bare the rocks beneath the soil, and disclosed the presence of the gems. Rare Earth elements or Rare Earth metals are a collection of 17 elements namely Scandium, Yttrium and Lanthanides (15 elements in the periodic table with atomic numbers 57 to 71 namely: Lanthanum (La), Cerium (Ce), Praseodymium (Pr), Neodymium (Nd), Promethium (Pm), Samarium (Sm), Europium (Eu), Gadolinium (Gd), Terbium (Tb), Dysprosium (Dy), Holmium (Ho), Erbium (Er), Thulium (Tm), Ytterbium (Yb) and Lutetium (Lu) )īeach Sand Minerals and Rare Earths are used as performance ingredients in consumer electronics, abrasive, automotive, renewable energy, ceramic, refractories, welding electrodes, telecommunication, aerospace, paints and pigments, gas mantles, petroleum, pharmaceuticals, nuclear power, etc.LaTouche T. Zircon, Monazite, Garnet and Sillimanite in Thoothukudi, Kanniyakumari, Tirunelveli, Ramanathapuram, Pudukkottai, Tiruchirapalli, Thanjavur, Nagapattinam, Thiruvarur, Cuddalore and Kanchipuram Districts. Ilmenite, Rutile, Leucoxene and non Titanium bearing minerals viz. The Beach Sand Minerals in Tamil Nadu contain Titanium bearing minerals viz. “Beach Sand Minerals” means economic heavy minerals found in the teri or beach sands, which are classified as Atomic Mineral as per MMDR Amendment Act, 2015 and AMCR 2016. Tiruvarur, Nagapattinam, Ramanathapuram, Thanjavur, Cuddalore, Ariyalur and Pudukkottai and carrying out exploration and mining of Oil and Gas since late nineteen fifties. Tvl ONGC Ltd.is granted with 25 Petroleum Mining Leases (PMLs) and 18 Petroleum Exploration Licenses (PELs)in the State spread over 7 districts Viz. Exploration and Exploitation of Crude Oil and Natural Gas The basin has suffered marine transgression resulted in the oil formations in the area and the number of criss-cross faults generated due the tectonic disturbances evolved as traps for the oil reserves in the area and hence all the exploration and exploitation activities for Oil and Gas are concentrated in these areas. The Cauvery Basin is a pericratonic rift basin evolved as a result of fragmentation of the Gondwana land during drifting of the India-Sri Lanka landmass system in the late Cretaceous. Most of the crude oil and natural gas reservoirs occur in geologic basins which are structurally controlled depending upon the nature of the sediment deposition in the area. The Cauvery Basin extending along the East Coast of India spread in Thiruvarur, Nagapattinam, Ramanathapuram, Thanjavur, Cuddalore, Ariyalur and Pudukkottai of the Tamil Nadu and in Pondicherry State and Karaikkal UT has been identified as one of the potential area for exploration and exploitation of oil and Natural Gas in the Country with major oil and gas discoveries, in both onshore and offshore. Since late nineteen fifties has emerged the state as one of the key oil province of India. The explorations for hydrocarbons especially the Oil and Natural Gas deposits in the sedimentary basins of Tamil Nadu by Tvl.
