7th printing printed in 1999. Several numbers are written in pencil on the first blank page; the rest of the pages are unmarked but the outer page edges have darkened in some areas from contact with a dusty shelf. One page has a small crease at the tip of the top corner, and approximately one-fourth of the pages have bent top corner (the book may have been stored standing upside down and at an angle). The the top layer on the cover is torn at the bottom of the spine, revealing the gray cardboard underneath. There are scratches on the back cover. The binding is strong. Despite the shelf-wear, the book remains a good reading copy. Additional Details ------------------------------ Product description: The renowned authors present a modern, unified treatment of economic geology, the study of geologic characteristics and the genesis of ores in the earth's crust. Ore deposits are explored in relation to plate tectonics, petrology and isotope and fluid inclusion techniques. Understanding how ore-bearing rocks form, say Guilbert and Park, is fundamental to understanding the nature, origin and distribution of ore deposits themselves. "...should be recommended reading for all students in this field of study." Mining Magazine "...the photographs are quite extraordinary...this book is not only a most valuable help for experts ...The Geology of Ore Deposits should not be missing in any library specializing in geo-sciences."
