第一届国际金伯利岩会议于1974年9月17日—10月8日在南非和莱索托召开了。与会者为亲自20个国家的代表,近二百名。参加这次会议的有从事发现和开掘金伯利岩以作为天然金刚石矿产的野外地质学家,和对金伯利岩的理论问题感兴趣的岩石学家、地球化学家和物理学家。非洲南部和其它地方金伯利岩的喷发把一系列特殊的岩石从地幔和地壳基底送到了地表。通过对这些岩石的研究,人们已经获得了有关地幔岩石学的大量资料。然而,要充分解释这些地幔样品则要求我们弄清金伯利岩本身的来源。会议的主要目的在于给代表们提供观察露天的和 The first session of the International Kimberley Conference was held in South Africa and Lesotho from September 17 to October 8, 1974. Nearly 200 participants represented 20 countries in person. Participants at the conference were field geologists engaged in the discovery and excavation of kimberlite as a natural diamond mineral and petrographers, geochemists and physicists interested in the theoretical issues of kimberlite. The eruption of the kimberlite in southern Africa and elsewhere sent a series of special rocks to the surface from the mantle and crustal basement. Through the study of these rocks, a great deal of information about mantle petrology has been obtained. However, to fully explain these mantle samples requires us to clarify the origin of the kimberlite itself. The main purpose of the meeting was to provide delegates with the opportunity to observe the open air
