Siliceous Deposits ia the Pacific Region. Developments in Sedimentolonv Volume 36. Edited by A. liiima. J. R. Hein and R. Sieve; Elsevier, 1983, 472 pp. $85.~00. PERHAPS BECAUSE the subject area is well-defined, this col-lection of papers from Second International Conference on Siliceous Deposits in the Pacific Region, 2 I-27 August, 198 f , is unusually cohesive. The introductory chapters, by R. Siever and by J. R. Hein and S. M. Karl, provide an excellent perspective with which to view the remainder of the volume. Siliceous (non-sand silica-bearing) deposits, including cherts, porcelainites, mdiolarites, and diatomites, are characterized by their mode of formation and occurrence. Succeeding sections of the book cover the distribution of siliceous deposits in space and time, their chemical sedimentology, their diagenesis, and diatomaaous sediments, followed by more detailed discussion of siliceous deposits in southwestern Japan and a proposal for the use of “chert-laminite” as a lithologic term.

ocEANooRApHERs, cagerto read the most recent in~lment of this excellent series, will not be disappointed. Volume 8 differs from its p ndeccssors because the editors have not attempted to give it a coherent subject theme, preferring instead to select topics in which there have been recent advances. The result is not simply a compilation of unrelated articles. There is an index to the whole volume and each chapter conforms to a uniform format which includes contents and comp&ensive re&rences Duplication has been avoided. John A. Cambell’s article on the Geochemical Ocean sections Study-GEDSECS details the numerous CX~ expeditions and describe-s their msults. He emphaaiaes isotope studies, sensibly leaving tmce metals to the succeeding chapter on Trace Elements in Sea-Water. This latter article by Kenneth W. Bruland exemplifies the need for this advan& series because it is ba& largely on results obtained within the past tive years. Elements are initially grouped and discussed according to their behaviour. Bruland then updates our knowledge of individual elements by systematically working through the periodic table. Natural Water Photochemistry has undergone a recent revival. 0. C. Zafiriou provides an overview
The individual papers in this volume are of varying quality. Most authors tied their in-depth knowledge of the formations into concise overviews. In some cases, better maps would orient the reader who is unfamiliar with the regional geology and geography. Some figures in the book are confusing due to inconsistent layout and coordination with the text. The book provides an excellent overview of siliceous deposits around the Pacific Ocean and elsewha. The numerous references for all chapten should enable the reader to study any aspect of the material in greater detail. This book is a recommended addition to the library of anyone who is interested in siliceous deposits.
