考察的省份包括葡萄牙（A. M. R. Neiva）、西班牙中西部（J. Saavedra）和撒丁岛（M. Biste）。非洲的含钽铌酸岩和伟晶岩以Bowden和Matheis等人关于尼日利亚各省的论文和Legg和Namateba关于赞比亚伟晶岩的论文为代表；对泰国含锡花岗岩也进行了讨论，Norman和Trangcotchasan的含锡花岗岩有利于岩浆流体的成矿，而不是来自大气海水。还报告了新斯科舍省的一个含锡过铝花岗质岩体和玻利维亚的许多锡矿床；Dulski等人认为玻利维亚第三纪锡斑岩一定从更古老的成矿地壳中继承了锡。更一般的论文涵盖了IVb组元素的矿物学和地球化学，锡-钨-钼金属化的分带以及锡和氟在自然组合中结合的原因，B. van de Pijpekamp报告说，使用53种矿物学，结构和结构特征的基质，可以从花岗岩杂岩的岩石薄片中获得锡势的测量。D. a . C. Manning的实验工作也强调了氟的重要性，他证明，在1kbar的温度下，向体系Q ab O或H 2 0加入4wt ~ F，最低液相温度降低100℃，最低熔点组成有相当大的变化。其他论文包括挪威的德拉门花岗岩、爱尔兰的伦斯特花岗岩和瑞典的前寒武纪花岗岩（Ubearing）周围的矿化报告。这本书提供了一个极好的洞察力，目前的想法，涉及与花岗岩有关的矿石成因的持续争议。显然迫切需要进一步应用现代化学和同位素方法，然后才能充分了解所涉及的过程，从而建立可靠的标准，用矿物学和地球化学方法识别潜在的含矿花岗岩。这本书制作精良，图表清晰，每篇论文都有丰富的参考文献。它合理的价格应该会吸引更多的读者。r.a.豪伊
provinces examined include those of Portugal (A. M. R. Neiva), west central Spain (J. Saavedra), and Sardinia (M. Biste). African t in-tantalumniobium acid rocks and pegmatites are represented by papers by Bowden and by Matheis et al. on Nigerian provinces and by Legg and Namateba on Zambian pegmatites; the Thailand tin-bearing granites are also discussed, Norman and Trangcotchasan favouring ore deposition from fluids derived from a magma rather than from meteoricconnate waters. Reports are also given on a stanniferous peraluminous granitic pluton in Nova Scotia and on the numerous Bolivian tin deposits; Dulski et al. consider that the Bolivian Tertiary tin porphyries must have inherited the tin from the older metallogenetic crust. More general papers cover the mineralogy and geochemistry of the group IVb elements, the zoning of tin-tungsten-molybdenum metallization and the reasons for the association of tin and fluorine in natural assemblages, and B. van de Pijpekamp reports that using a matrix of fifty-three mineralogical, textural, and structural features, a measure of tin potential can be obtained from thinsections of the rocks of granitic complexes. The importance of fluorine is emphasized also by the experimental work of D. A. C. Manning who demonstrates a 100 ~ lowering of the minimum liquidus temperature and a considerable change in minimum melting composition for the addition of 4 wt. ~ F to the system Q A b O r H 2 0 at 1 kbar. Other papers include reports on mineralization around the Drammen granite, Norway, the Leinster granite, Ireland, and Precambrian granites (Ubearing) in Sweden. The book gives an excellent insight into current thinking on the continuing controversies involving ore genesis associated with granitic rocks. Further applications of modern chemical and isotopic methods are clearly urgently needed before sufficient understanding of the processes involved can lead to the establishment of proven criteria for identification of potential ore-bearing granites by mineralogical and geochemical methods. The book is well-produced with clear diagrams and abundant full references with each paper. Its reasonable price should encourage wide readership. R. A. HOWIE
