摘要:

After splitting from Gondwanaland, India drifted northwards to collide with the Asian landmass about 40 million years ago. The intervening Tethys ocean was closed by northwards subduction beneath southern Tibet, and the collision created the Himalayan orogenic belt. Continuing northward movement of India at a rate of about 5 cm per year over the last 40 million years has caused it to indent Asia, and the resultant massive shortening is expressed by thrusting of the northern margin of India, by faulting and earthquakes in the Himalayas and China, by rifting and faulting in Tibet, and by the uplift of the Himalayas which is still continuing at rates of up to several millimetres per year.

摘要:

The most profound advances in the Earth sciences during the next decade will not be made on Earth. This paradoxical situation has come about because, while it is becoming more and more difficult to find new approaches to investigating the planet we are so familiar with, by the end of the decade we will have had the opportunity to study a second planet that is remarkably similar to the Earth, but one that has evolved quite differently: Venus. Such study may help us to learn why the Earth evolved in the way that it did, with the unique combination of surface conditions that allow life to be sustained.

摘要:

The past four decades have seen an unprecedented development of metal exploration techniques because as exposed and easily exploitable mineral deposits have been used up, exploration geologists have been forced to find new ways of looking deeper into the crust.
