印度洋板块向北漂移是地球科学中的一个著名问题。它对我国青藏高原和喜马拉雅山的隆起和形成有着关键性的作用。目前大多数科学工作者赞同板块理论中的俯冲说,认为印度洋板块俯冲到欧亚板块之下。而美国麻省理工学院莫尔纳(Peter Mo-lnar)教授等人提出了地壳缩短学说来说明两板块碰撞后的运动情况。我国科学工作者朱湘元、刘椿等所作的西藏林周古地磁工作(详见《地质科学》1977年第一期44—51页的论文)为莫尔纳教授所采用。他指出:这些新的古地磁资料与他的地壳缩短理论相吻合。他的这项研究得到了美国国家基金会的支持。地壳缩短学说在我国介绍得不多。它是地球科学中的一种新观点。本刊介绍它,不仅有利于不同科学学派的百花齐放,而且对我国青藏科考工作可能会有实际参考价值。英国《自然》杂志1978年5月273卷刊载莫尔纳和陈(Wang-Ping Chen)合写的《亚洲新生代地壳大规模缩短的证据》一文,论述了地壳缩短学说,摘译如下,供参考。
The Indian Ocean plate drifting north is a well-known issue in geosciences. It plays a key role in the uplift and formation of the Qinghai-Tibet Plateau and Himalayas in our country. At present, most scientists agree with the subduction in plate theory that the subduction of the Indian Ocean plate under the Eurasian plate. The United States, Massachusetts Institute of Technology Professor Molnar (Peter Mo-lnar) and others put forward the crustal shortening theory to illustrate the movement of two plates after the collision. The ancient geomagnetic work of the Linzhou in Tibet made by Chinese scientists Zhu Xiangyuan and Liu Chun (for more details, see the article “Geological Science”, pp. 44-51, first issue, 1977) was adopted by Professor Molnar. He pointed out: These new paleomagnetic data are consistent with his crustal shortening theory. His research was supported by the U.S. National Foundation. Crustal shortening theory is not much introduction in our country. It is a new idea in earth science. This article introduces it, not only conducive to the blossoming of different science schools, but also may have practical reference value for our Qingzang scientific research work. 1978, Volume 273, May 1978, published a paper entitled “Evidence of Massive Shortening of Cenozoic Crust in Asia,” co-authored by Wang-Ping Chen and discusses the theory of crustal shortening. reference.
