Magmatic Sulfide Deposits. Geology, Geochemistry and Exploration. ANTHONY
J. NALDRETT. Pp. 727; 325 illustrations. Hardcover. Springer, XV. ISBN:
3-540-22317-7. 2004. US$179.00.
Tony Naldrett, Professor of Economic Geology at the University of Toronto,
has worked on magmatic sulfide deposits for more than 40 years, including some
of the major deposits around the world, and he is an international authority on
these ores. This book, which is an updated version of the Naldretts original
book published in 1989, provides a welcome personalized overview of the current
ideas on the origin of Ni-Cu sulfide deposits and the tremendous advances that
have been made in their understanding during the last two decades. These ideas
are supported by well-designed maps, by quantification of tonnages and grades,
and by ample references to earlier works.
This book contains 10 succinct and informative chapters. The first two
chapters provide an introduction to the classification scheme and some general
concepts related to the origin of the deposits. In chapter 1, the different
deposits are classified, in terms of their metal contents, into Ni-Cu sulfide
deposits and PGE deposits. The Ni-Cu sulfide deposits are further subdivided
into six classes on the basis of their associated magma types. On the other
hand, the PGE deposits are subdivided according to the morphologies of orebodies,
as well as by mineralogical associations. Tonnages and ore grades are also
discussed in this chapter. In chapter 2, factors affecting sulfur solubility in
mafic magmas are . . . [Full Text of this Article]
