随着工农业生产的发展和科学技术的进步,人们从地下开采的各种矿产资源的数量与日增多,做为非再生资源,陆上的资源储量正在日益减少,这种必然的趋势,引起很多地质学家和经济学家的忧虑。可是占地球表面积71％的海洋,除石油和天然气被部分开发利用外,其它矿种仍待开发。因而,近二十多年来对海底地质及其矿产的研究日益引起人们的重视,成为发展迅速的领域之一。目前,愈来愈多的科学事实表明,海洋将会成为人类开采多种矿产资源的主要基地。关于海底矿产研究的论著是比较多的,可惜多分散刊登在各种刊物上,为弥补其不足,D.S.Cronan系统地将海底矿产研究成果编入了他的《水下矿物》一书,此书的出版,必将得到广大海洋地质科技工作者的欢迎。 《水下矿物》由英国伦敦科学出版社出版(1980年)。全书共三百五十多页,附大量图表。该书除前言外,共分为十章论述。第一章通论。概述海底的自然地理分带及矿产资源的潜力、输入海洋物质
With the development of industry and agriculture and the advancement of science and technology, the amount of various mineral resources mined by underground people has been increasing with each passing day. As a non-renewable resource, land resources reserves are declining day by day, and this inevitable trend has caused many Worries of geologists and economists. However, accounting for 71% of the Earth’s surface area of the ocean, with the exception of oil and gas are partially exploited, other minerals still to be developed. Therefore, the researches on seabed geology and its minerals have drawn more and more attention in recent two decades and become one of the rapidly developing fields. At present, more and more scientific facts show that the ocean will become the main base for mankind’s exploitation of various mineral resources. There are many works on the research of seabed minerals, but it is a pity that they are published in various journals. In order to make up for the deficiency, DSCronan systematically compiled the research results of seafloor minerals into his book “Underwater Minerals” Of the publication, will certainly be welcomed by the majority of marine geology scientists. “Underwater Minerals” published by London Science Press, England (1980). The book a total of three hundred and fifty pages, with a large number of charts. In addition to the preface, the book is divided into ten chapters. The first chapter general theory. Summarize the potential of the natural geography of the seabed and its mineral resources and import marine material
