Hydrothermal iron oxide copper-gold and related deposits. Volume 2 / Медно-золотые месторождения в железистых кварцитах

This preface presents the background to this book, the second volume of the "Hydrothermal Iron Oxide Copper-Gold & Related Deposits - A Global Perspective" series, and briefly discusses the rationale for inviting the papers it contains, their format and what it is hoped the volume will achieve. It also offers some observations on the unifying characteristics of the iron oxide copper-gold family of deposits and what they may represent in a broader context.

The "hydrothermal iron-oxide copper-gold" (IOCG) family and related deposits continue to attract keen interest, both as the subject of academic research and as arguably the most sought after mineral exploration target in the world today.
This interest has been reflected by the strong demand for the first volume of "Porter, T.M. (Ed.), 2000 - Hydrothermal Iron Oxide Copper-Gold & Related Deposits - A Global Perspective". That volume was published as a companion to the conference of the same name convened by the Australian Mineral Foundation in Perth, Western Australia, on 4-5 December 2000, the technical program of which was organised by Mike Porter of Porter GeoConsultancy. The first edition sold out within 6 months and a second printing was commissioned in June 2001. The second edition was published by PGC Publishing in March, 2002.
To further satisfy the obvious need within the industry, it was decided that a second volume should be compiled comprising twenty all new papers to complement the first. This book, also published by PGC Publishing, is the result.
This second volume is intended to complement and build upon the first (Porter, 2000). The regions, deposits and subjects in both have been carefully selected to provide a comprehensive global coverage, with appropriate expert authors from both industry and from academia having been invited to contribute papers to achieve that coverage.
While this volume contains a few less papers than did its predecessor, they are on average larger and more exhaustive, resulting in a thicker book.  The bulk of the contributions relate to individual deposits, prospects or provinces, and have been geographically sub-divided, as in volume 1, into those from Australasia, The Americas, and Africa & Eurasia, with just one general paper discussing the geophysical expression of the IOCG deposits and their settings.
The editorial intent for both volumes has been to present descriptive detail and observations from a wide variety of IOCG examples from around the world, accompanied by the interpretations and conclusions that may be drawn from those observations.At the outset, a broad outline of the content and scope of each paper was agreed with the respective author(s), depending on the character of the subject deposit or province and what it might contribute to an understanding of the IOCG family. In addition, each author was asked to include details of the tectonic, geologic and metallogenic setting of the province under discussion or that which embraced the subject deposit, followed by a more detailed description of the geology, structure, alteration, mineralisation, mineralogy, geochemistry and other key characteristics of the subject deposit or deposits of the province. In addition authors were asked to address the occurrence of associated iron oxides, how they were fonued/ernplaced, the controls of mineralisation, and the spatial, temporal and chemical relationships between the iron oxides and the associated economic mineralisation, both on a property scale, and regionally.
It is not intended that the two volumes be composed of papers that merely reveal the "absolute truths" on the origin of these deposits from positions of authority, but rather that readers are presented with a range of factual descriptions, observations and differing opinions that provide the opportunity for them to draw their own informedconclusions. Indeed there has been a definite intention to include the conflicting opinions that are argued in the literature, although the authors involved have been asked to support their interpretations by hard observations and careful reasoning (eg. Barton and Johnston, 2000; Pollard, 2000; Naslund, et ai, this volume).In addition, as will become apparent from studying the papers in these two volumes, this family of deposit does not comprise a single ore type, but represents a family of loosely related deposits with a common elemental association and overlapping characteristics. As such the conflicting views presented are found to be applicable to different branches of the family, while none are necessarily all embracing.
Since the recognition of this family of deposits a wide range of examples have been cited within the literature as being members. As we learn more about them it has become apparent that not all should be readily accepted into the family. Never-the-less, papers have been invited to describe some of these less obvious relatives that are found in association with accepted members, and to discuss whether or not they should be incorporated into the family as well as their links, if any to it (eg. Maksaev and Zentilli, this volume and Boric, et ai, this volume).
In a similar vein, it is apparent that deposits may belong to the family, while also being classified as another distinct ore style (eg., some are also classified as skarns, see Injoque, this volume and Herington, et ai, this volume; some have carbonatite associations, see Vielreicher, et ai, 2000 and Harmer, 2000; while others exhibit the influence of many of the processes normally associated with sediment hosted copper ores, see Boric, et ai, this volume). This emphasises the earlier observations that the family does not represent a single ore style but a group of deposits with common elemental associations and overlapping characteristics, but no over-arching genetic model.
