Granite is a common type of intrusive, felsic, igneous rock which is granular and phaneritic in texture. This rock consists mainly of quartz, mica, and feldspar. Occasionally some individual crystals (phenocrysts) are larger than the groundmass, in which case the texture is known as porphyritic. A granitic rock with a porphyritic texture is sometimes known as a porphyry. Granites can be pink to gray in color, depending on their chemistry and mineralogy. By definition, granite is an igneous rock with at least 20% quartz by volume. Granite differs from granodiorite in that at least 35% of the feldspar in granite is alkali feldspar as opposed to plagioclase; it is the alkali feldspar that gives many granites a distinctive pink color. Outcrops of granite tend to form tors and rounded massifs. Granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels. Granite is usually found in the continental plates of the Earth's crust.

NGRI finds Gas Hydrate Reserves along East Coast of India

India’s National Geophysical Research Institute has identified hydrate gas reserves along the east coast of the country, a scientist from the institute said. According to estimates, the reserves are said to be at least 1,500 times the country's current fossil fuel reserves - coal, oil and natural gas put together. Gas hydrates are crystalline solid and ice-like minerals that form at low temperatures and high pressure in the deep sea. Hydrates contain gases, such as hydrocarbons that glue themselves inside symmetrical cages of water molecules to form hydrate crystals. The hydrate reserves are found in Krishna-Godavari basin, Mahanadi basin and Andaman region. These reserves are located at 500 meters deep in the sea and at present it is not economically viable to extract them with the available technology. According to him, even if one per cent of the gas hydrate reserves are tapped, it would support country's fuel requirements for ten years. Government of India formulated the National Gas Hydrate Programme (NGHP) in 1997 for exploration and development of gas hydrates resources of the country.

Hirakud Dam-Longest man-made dam in the world

Hirakud Dam was constructed across the river Mahanadi, which was located about 15 km from Sambalpur, Orissa, India. It was constructed during 1957, the dam was regarded as one of the world’s longest earthen dam. The dam extends a lake, Hirakud Reservoir, which was about 55 km long. Hirakud Dam was regarded as the longest man-made dam in the world, at a length of about 26 km. It was one of the first major multipurpose river valley project started in India after independence.

Kudankulam likely to generate power in a month

CHENNAI: With fine-tuning of systems still on, power generation at the first 1,000 MW unit of the Kudankulam Nuclear Power Project (KNPP) is expected to happen October-end or November, a senior official said Saturday. "Fine-tuning of systems are on. WE have gone up to 20 percent/200 MW power levels. We might start running the turbine next week. We have not run the turbine till now. WE are not in a position to put a date as to when the unit would be connected to the grid," R.S. Sundar, site director of the KNPP told IANS over phone from Kudankulam. Sundar said the connection to the grid too is expected to happen October or November. The first unit at Kudankulam 99.74 percent complete, as of August 2013, officials said. The Nuclear Power Corporation of India Limited (NPCIL) is setting up two 1,000 MW Russian reactors at Kudankulam in Tirunelveli district, around 650 km from here. KNPP is India's first pressurised water reactor belonging to the light water reactor category. The first unit attained criticality, which is the beginning of the fission process, for the first time, July 13. The NPCIL had earlier said it would connect the first unit to the grid end-August, generating 400 MW power. But that did not happen due to two condenser valve problems which seem to have got stuck. "Everything is fine on the reactor side. The problem was at the electrical systems side and it was also sorted out," the source said. The second unit at KNPP is expected to start commercial operations in June next year. The unit has achieved progress of 95.50 percent as of August. The NPCIL has loaded dummy fuel assemblies in the second unit. The dummy fuel assemblies are made of lead, instead of uranium, and are the exact replica of the actual nuclear fuel assemblies, both in dimension and weight. A total of 163 dummy fuel assemblies have been loaded into the core. According to a source, NPCIL has decided to train its focus on successful commissioning of the first unit and hence the work on the second unit is going a bit slow.
