Mineral Deposits, and the Chinese Academy of Geological Sciences. It is an academic publication consisting of original papets dealing with basic problems of ore genesis, ore-forming mechanisms and fundamental problems of metallic and non-metallic ore deposits Some space is devoted to reports about academic activities, reviews and discumions of mineral deposits. Papers are in Chinese, but include one to two page abstracts in English and an English table of contents Beginningin 1983,thenamesonalldiagmmswilIbeinEnglish while from 1984 the names and legends of all diagrams will appear in ChineJbEnglish bilingual form.
Two issues were published in 1982, but quarterly pub lication will start in 1983. Inquiries may be addmmed to: Editorial Department of Mineral Deposits, Institute of Mineral Deposits, Chinese Academy of Geological Sciences, Baiwanxhuang Road, Beijing, People’s Republic of China.

The data base must surely be cxbaustivc, including 43 pagesofrefemnces to individual analysis sets. Whether tbe consensus values will be accepmd universally is of comse a question for individual decisions. Editor K. Govindaraju is to be commended for his enterprke in finding the means to publish this useful compilation. Unfortunately tbe binding is not sturdy enough for the extensive use which the issue will experiena.
THE INTENTION of a book review is to draw the attention
of readem to important new publications in book form, and to comment on the timeliness, usefulness and success of the book. Although this article is not a M it appeamd appropriate to alert readers to its publication, for there is no doubt that it will be used extensively by analytical geochemists for some time to come. The authors am to be congratulated for their industry in compiling and screening the analytical results with a view to selecting *‘consensus values” on a widely-used set of standard reference samples.

THIS BOOKis being reviewed from the viewpoint of one who
uses XRP for the analysis of rocks. As I am not involved in research/development aspect, I am looking for a text that will bring me up to date and help keep my quantitative pmcedures at the “state-of-the-art”. This book certainly helps. Part of the book is background material that is available in other texts-physics of X-rays, absorption, scatter, counting statis&, etc. It is well written, but there is nothing new. The authors give a nice treatment of the theory of.X-ray emission from the sample for both monochromatic and poiychromatic primary excitations including secondary and tertiary fluorescence yields (enhancement factors, crossed etfects). Their treatment ofthe concept ofthe effective wavelength in polychromatic excitation is well done. The main part of the book, and the authors’ main contribution, is Chapter 8-16 where they discuss the quantitative analysis of homogeneous specimens. There is a long chapter (10) on compact specimens (i.e. no dilution) which contains a good discussion on the development and use of influena coefficients. Chapters 1 I - 14 discuss both high and low degrees of dilution and explain the approximations that

are possible, such as calculating au&cients for oxides, or “modified” a&cients and their apphcation to the analyses of silicates. The double dilution method, in part da veioped by the senior author, is pmposed as ‘potentially a powerful and universal method of quantitative analysis”. One of the most significant p&us made is that the computer/micro pmceasornowmakesmatbematicalmethodsqf matrix cormctions much more feasible, and analysts should look to these and move away from tbe very high dilution/ heavy absorber methods with their amoc&ed loss of Line intensities. For the beginner, Chapter 18 is a good review of sample preparation of powder4 and fused discs. However, it does not bring out the problems of achieving (and the importance of) homogeneity in glassdiscs. The book contains over 400 r&rences up to 1979 (only three are later) and six appendices: wavekngths of K, Land M series lines; mass attenuation c&ficients; and the spectml distributions of the Cr and W X-ray tubes.

The first chapter deals with generahties of the global phosphorus cyck, it covers well all the major points of phosphorus biogeo&emistty. There are some arguabk estimates
