International team conducts field tests in Cauvery Sheer Zone

Finding proof: Members of the International Geological Expedition conducting a study in Kadavur area of Karur district.

KARUR: An international geological expedition, comprising research scholars and reputed geologists from India, Australia and Japan, conducted field tests and experiments in the Palakkad Cauvery Sheer Zone over the past week. The team is looking to find and piece together geological and structural evidences to support the Gondwana land mass theory that suggests that South America, Africa, Madagascar, India, Sri Lanka, Antarctica and Australia formed part of a single monolith land mass called Gondwana _ hundreds of million years back.

The Gondwana theory propounds that these lands got separated under a phenomenon called seafloor spreading and the great continental drift could have happened at least 200 million years back.

The Indian arm of the team comprised T.R.K. Shetty and Ellappa, Scientists with the National Geophysical Research Institute, Hyderabad, while the Japanese team comprised M. Santhosh of Ko Chi University, Japan, and Chief Editor of Gondwana Research, a reputed professional journal, Tsunogae, Associate Professor, Tsukuba University, his colleague Prof. Sato and two other research scholars from Japan. Allen Collins of Adelaide University and seven others from Australia made up the team. Research Scholar R. Mohandoss of the Department of Geology, National College, Tiruchi, assisted the team in its quest in the region.

Team visits districts

The 15-member international team visited several areas of Salem, Erode, Coimbatore and Tirupur districts before descending on Karur district. All those areas form part of the Palakkad Cauvery Sheer Zone. Rock testing and sampling were done at Kanjamalai (Salem district), Tiruchengode, Kangeyam, Paramathy (Namakkal district) in the past fortnight before they started to look for clues to solve the Gondwana theory in the geologically important areas of Taragampatty, Kadavur, Ayyarmalai, Chinnampatti (all in Karur district) and Gujiliamparai (Dindigul district) over the past week.

In the South Indian landmass there are several sheer zones such as Achankoil Sheer Zone, Moyar Bhavani Sheer Zone, Salem Attur Sheer Zone, and Kangeyam Karur Tract (where a lot of gem stones occur). The team has been visiting and conducting research in all countries and areas associated with the Gondwana theory. From Karur they have taken rock samples to Australia and Japan to conduct a slew of studies. At the same time they detected the age of specific rocks and formations at the field level to be classified and enhanced further using laboratory tests and calculations. The studies would also help them analyse the sheer zones, mineralisation and geological structures. The governments of India, Australia and Japan are funding the project.

Karur district assumes great geological importance since it is a suture zone linking Palakkad Cauvery Sheer Zone with two or more tracts that are smaller in dimension, according to the researchers. Significantly in Kadavur area of Karur district deposits of Anorthosite, a monomineralic rock that gives the Moon its radiance and glitter is found in noteworthy quantum. In Tamil Nadu Anorthosite is found only at Kadavur, Oddanchatram and Siddhampoondi near Tiruchengode.

Chennai: From a small three-square mile given to the East India Company, where Fort St. George now stands, started an odyssey on August 22, 1639. Today, the journey is still on with Chennai growing, as a melting pot of cultures, a bustling centre for trade and commerce and many more developments to come.

Chennai turned a year older on Saturday, something which the organisers of the Madras Week celebrations made sure one participated in or at least talk about. A celebration that started with only a day has become a fortnight of festivities, learning and sharing. Even the organisers agree that the number of people and organisations lending support has increased greatly over the years.

If a canvas of literary and cultural events has already kept Chennaiites busy the last week, then D-Day had to be even more special. From book launches, talks, discussions and release of a special cover on the city, it looked like every important pocket in the city had a function to mark the day.

Stamps are an authentic source of information on the heritage of the city and their potential has to be tapped. This was highlighted at an event conducted by the postal department. “The possibility of bringing out stamps on the heritage structures such as Ripon Building has to be explored by the Chennai Corporation,” said T.S. Ramanujam, Post Master-General, Chennai.

He said: “We could proactively get in touch with the government departments on chronicling the heritage of the city by designing more stamps.”

Mr. Ramanujam said the department would organise small presentations on the heritage of the city. Chennai Corporation has been focussing on restoration of heritage structures in the city, said its Commissioner Rajesh Lakhoni. An exhibition of old maps, photographs, books and coins on Madras was inaugurated by the Madras Heritage Lovers. Founder of Madras Heritage Lovers D. Hemachandra Rao said, “The exhibition is a window to the city’s past.” The special cover on the theme ‘bridges of prosperity’ depicts graceful arch bridges of Madras. The design includes St. George’s Bridge and the cancellation shows Law’s Bridge of Chintadripet. Eight selected bridges across the Cooum, Adyar and the Buckingham Canal are part of the design on the reverse side of the cover.

Cultural organisations also joined in to pay tribute to the city. Personalities from politics, literature, cinema, music, social service and civil service, who contributed to the development of Madras, gathered to talk about their contribution to the city and vice-versa.

Musician K.J. Yesudas said he borrowed Rs.16 from a taxi driver to get a ticket to Madras. Yesteryear actress Sheela recalled her association since the time she was brought to the city by S.S. Rajendran and the effort she made to learn the language. “I came to Tamil Nadu to become an actor and I owe it to the State for what I am today,” she said. If Madras was better known as the film city, a talk on its journey must be part of its celebrations. As part of the celebrations on Saturday, Mohan Raman gave a glimpse of ‘Madras as seen in the films’ of 1938-78.

Gandhi and Tamils in South Africa, his public meetings, places where he stayed, interactions with Tamil leaders, are part of an exhibition ‘Gandhi in Tamil Nadu,’ organised as part of Madras Week at Roja Muthiah Research Library, Taramani.

Tamil Nadu and Karnataka stick to stand on hydro power projects

IN DISCUSSION: H.S. Brahma, Union Power Secretary, chairing a meeting in Chennai on Monday. The meeting was attended by officials of Tamil Nadu, Karnataka, Kerala and Puducherry governments apart from those of the Centre.

CHENNAI: Even as Tamil Nadu and Karnataka stuck to their respective positions on the Cauvery Hydro Power Project proposals, the Centre, after holding a meeting with all Cauvery basin States, on Monday announced that one more meeting would be held in Bangalore by November-end.

[The project envisages the establishment of four power plants, two each in Tamil Nadu (Rasimanal: 360 MW and Hogenakkal:120 MW) and Karnataka (Shivasamudram: 345 MW and Mekadatu: 400 MW) by the National Hydro Power Corporation (NHPC)].

“Some progress made”

Union Power Secretary H.S. Brahma told reporters: “Definitely, we made some progress today. We would like to discuss further details of these four projects.” Describing the meeting as a confidence-building measure, he called upon the States to trust each other so that pending issues could be resolved.

He expressed the hope that by November end or early December, issues concerning the two components – Shivasamudram and Hogenakkal – would be resolved.

Of the four components, only Shivasamudram had been cleared by the Union Environment and Forest Ministry, Central Water Commission and the Central Electricity Authority.

In respect of Hogenakkal, about 800 hectares would be submerged, most of which belonged to the government.

Mr. Brahma suggested the formation of an oversight committee for the project execution.

Tamil Nadu’s Principal Secretary (Public Works) S. Ramasundaram said the State was for the execution of all the plants through the NHPC.

Responding to Mr. Brahma’s suggestion for resolving the issues bilaterally in the wake of the goodwill generated by the unveiling of statues of Thiruvalluvar and Sarvajna in Bangalore and Chennai, Mr. Ramasundaram said the discussions at the level of Chief Ministers of both States could be held if Karnataka made good the present shortfall of 20 thousand million cubic feet (tmcft) in the current irrigation season since June. The Krishnaraja Sagar and Kabini reservoirs in Karnataka were full, he pointed out.

In February, Chief Minister M. Karunanidhi had written to Prime Minister Manmohan Singh to prevail upon Karnataka not to take up the Shivasamduram component unilaterally, pending the notification of the Tribunal’s final award, Mr. Ramasundaram said.

Karnataka’s Principal Secretary (Energy) K. Jairaj expressed the State’s keenness to establish the Shivasamudram plant on its own as the site was entirely within its border and the project did not involve consumptive use of water. “While we strictly adhere to the award of the Cauvery Water Disputes Tribunal to ensure that there is no consumptive use of water, we should be allowed to execute the project.”

Karnataka would be “more than willing to provide” whatever oversight mechanisms were required for the project in view of the severe power shortage.

As for other components, Mr. Jairaj said Karnataka was ready to talk about the mode of execution.

Representatives of Kerala and Puducherry attended the meeting.
