这是A.哈勒姆，其中作者谁是经验丰富的教师，以及高学术地位已被要求提供一个简短的介绍，他们的主题主要是为本科生。本书分为三个部分，第一部分原则（72页），II.更重要的矿石存款类型的例子（115页），和III空间和时间的矿化（22页）。第一部分在介绍定义的一章之后，讨论了矿床的性质和形态，包括矿体的形式;矿石和脉石矿物的结构和结构、流体包裹体和围岩蚀变;矿石成因的主要理论;地质温度测量、地质压力测量、稳定同位素研究、古地磁和放射性测年和分带;成矿区和时代。第二部分首先简要介绍了矿床的分类。作者指出最近从遗传到环境岩石组合分类的转变，并采用了后者，但也承认有一点“起源和形态”。概述的特征主要基于Lindgren 1913年的高温、中温、浅成热液和远成热液矿床方案。第二部分的其余部分包括11章，其中描述了各种不同环境中矿石的主要产状-正岩浆岩、碳酸岩、火交代岩、浸染状和网状岩、沉积和火山地区的层状硫化物和氧化物、矿脉组合、层控、沉积、残余和表生富集、变质。章节的名称本身往往就有一个遗传戒指。第三部分有两个简短的章节板块构造和全球分布的矿床和矿化通过地质时间。这本书的内容摘要表明，治疗必须是简短的，有时几乎是敷衍了事，因为一些（opics涵盖需要一卷自己。即使是主要的矿床也只需要一两页纸，因此可能缺乏许多细节和对矿床成因的相互矛盾的观点的讨论。在这样一本书中，一定会有一些遗漏，有些人会发现自己的专业被遗漏或被简要提及。然而，作者已经在主要实现了他的目标，提供了一个平衡的，简短的和廉价的（当然是平装版）介绍一个不断扩大和复杂的主题。这本书写得简明扼要，插图清晰，布局合理;印刷错误很少。有一个全面的参考书目，学生可以求助于它，因为他的胃口已经被简明扼要的描述所激起，或者有一些更基本的方面，如年代测定或稳定同位素或流体包裹体更充分地解释。这是一个及时的工作在几个方面。它强调了一个矿体如何可能是一系列作用于长期地质历史的过程的结果;它指出了技术变革的影响，这些技术变革使许多不经济的矿床变成了可开采的矿体（如1900年铜浓度为3 ~o，目前为0.4 ~o）;而且它出现在许多长期建立的理论，例如许多矿石的表观起源受到质疑和同生起源被提出的时候。埃文斯博士是值得祝贺的这卷可以强烈推荐给广大读者作为一个很好的介绍矿石地质学。R.布拉德肖
This is the second of the Geoscience Text series edited by A. Hallam in which authors who are experienced teachers as well as of high academic standing have been asked to provide a brief introduction to their subject mainly for undergraduates. The book is divided into three par t s I Principles (72 pp.), II Examples of the More Important Types of Ore Deposit (115 pp.), and III Mineralization in Space and Time (22 pp.). In Part I, after an introductory chapter on definitions, there is a discussion of the nature and morphology of ore deposits including forms of orebodies; textures and structures of ore and gangue minerals, fluid inclusions and wall rock alteration; major theories of ore genesis; geothermometry, geobarometry, stable isotope studies, palaeomagnetic and radiometric dating and zoning; metallogenic provinces and epochs. Part II begins with a brief account of the classification of ore deposits. The author points to the recent swing from genetic to environmentalrock association classifications and adopts the latter himself but does admit to a 'whiff of genesis and morphology'. The features outlined are based mainly on Lindgren's 1913 scheme of hypothermal, mesothermal, epithermal, and telethermal deposits. The rest of Part II consists of eleven chapters in which are described the principal occurrences of ores in a wide variety of different environments-orthomagmatic, carbonatite, pyrometasomatic, disseminated and stockwork, stratified sulphides and oxides in sedimentary and volcanic areas, vein associations, strata-bound, sedimentary, residual and supergene enrichment, metamorphic. The very names of the chapters often have a genetic ring. Part III has two brief chapters on plate tectonics and the global distribution of ore deposits and ore mineralization through geological time. This summary of contents of the book indicates that the treatment must necessarily be brief, sometimes almost perfunctory, since some of the (opics covered need a volume to themselves. Even major deposits warrant only a page or two so that many of the details and discussion of conflicting opinions on the genesis of the deposits may be lacking. In a book of this size there must necessarily be some omissions and there will be some who find their own speciality either omitted or briefly touched upon. However the author has in the main achieved his aim of providing a balanced, short and cheap (certainly for the paperback edition) introduction to an ever expanding and complex subject. The book is concisely written, well illustrated with clear line drawings and well laid out; there are very few typographical errors. There is a comprehensive bibliography to which the student can turn either because his appetite has been whetted by the succinct summary descriptions or to have some of the more fundamental aspects-such as dating or stable isotopes or fluid inclus i o n s m o r e fully explained. It is a timely work in several ways. It emphasizes how an orebody may be the result of a whole series of processes acting over a long geological history; it points to the effects of technological change which have made many uneconomic mineral deposits into workable ore bodies (e.g. Cu concentration 3 ~o in 1900, 0.4 ~o at present); and it comes at a time when many of the long established theories, e.g. the epigenetic origin of many ores, are being questioned and a syngenetic origin is being suggested. Dr Evans is to be congratulated on this volume which can be strongly recommended to a wide range of readers as a good introduction to ore geology. R. BRADSHAW
