Permo-Triassic collision, subduction-zone metamorphism, and tectonic exhumation along the East Asian continental margin

Article Abstract:

Permo-Triassic collision, subduction-zone metamorphism, and tectonic exhumation along the East Asian continental margin were analyzed. It was observed that convergent plat motion was responsible for Tongbai-Dabie-Sulu (east-central China)-Imjingang-Gyeonggi (central Korea)-Renge Suo (Southwestern Japan)-Sikhote-Alin orogen along the paleo-Pacific edge of cratonal Asia which reflects collision between the Sino-Korean and Yangtze cratons.

President announces $183 million for protecting oceans and coasts

Article Abstract:

The National Oceanic and Atmospheric Administration (NOAA) will receive $183 million as its share in the $1 billion allotted for Pres Clinton's Lands Legacy Initiative for increasing federal government support for the protection of natural resources. The NOAA is tasked to step up protection efforts for the country's most important ocean and coastal areas, and encourage environment-friendly economic growth strategies along the coasts.

The Aral Sea disaster

Article Abstract:

The Aral Sea, which is located among the deserts of Central Asia has been repeatedly filled and dried due to natural and well as human encroachment. Measures to at least preserve and rehabilitate some parts of the lake need to be carried out.
