Geology Applied to Engineering, Second Edition, represents a significant and insightful update of the first edition. Abdul Shakoor, Emeritus Professor, Kent State University, Ohio, has joined Terry West, Professor, Purdue University, Indiana, in the revision of the first edition. Together, they:
• Effectively and strategically reorganized the arrangement of chapters so that they are cohesive and build on material that is germane to related subjects.
• Added a new chapter that is solely dedicated to the evaluation of construction materials (Chapter 9).
• Expanded the coverage and scope of important topics such as the engineering properties of rocks (Chapter 8), slope stability and ground subsidence (Chapter 15), and significant fields in engineering geology, such as highways, dams, tunnels, and rock blasting (Chapter 21). <...>

The content and technical level of a geology text for engineers is a matter of broadly differing opinion. The type of geology course required for engineering students at llniversities around the United States varies from introductory physical geology, earth science, engineering geology, or to no course at all. This situation results from diHerences in philosophy, engineering curricula, and geology faculty available to teach such a course. Geologi; fo·r Engineers and Envirom11tmtnl Scientists is an attempt to provide a broad introduction to the earth sciences with an emphasis on engineering and environmental applications of the science <...>

Mongolia is situated between the Siberian and North China platforms and includes several Precambrian continentalblocks, which are fringed by Paleozoic and Mesozoic magmatic arcs, accretionary complexes and trapped oceanic crusts (Sengör et al., 1993). A number of porphyry, skarn and vein-type hydrothermal deposits have been discovered along these extinct magmatic arcs through regional geological mapping (Jargalsaihan, 1996). Thesedeposits form several metallogenic belts, which are genetically related to regional magmatism and tectonics (Distanov and Obolenskii, 1994; Dejidmaa, 1996). Although geology, alteration and mineralization of these deposits

have been described in explanatory reports of geological maps (e.g., Zabotkin, 1988), only a few geochronological studies have been undertaken for hydrothermal deposits (Sotnikov et al., 1974, 1995; Lamb and Cox, 1998; Muraoet al., 1998). The scarcity of age data for ore deposits makes it difficult to comprehend metallogeny in Mongolia. The Geological Research Center of Mongolia conducted a comprehensive project that re-examined geology (Teraoka et al., 1996), magmatism (Takahashi et al., 1998) and mineral deposits in the Bayankhongor region in central Mongolia (Fig. 1), where many hydrothermal deposits are associated with granitoids. This paper presents geology and K-Ar ages of the South, Huh Bulgiin Hundii, Saran Uul, Taats Gol and Han Uul deposits in the Bayankhongor region, and discusses metallogeny related to Paleozoic magmatism in the region.

Geology of Australian and Papua New Guinean Mineral Deposits heralds a new era in  the publication of The AusIMM Monograph Series. The new methodology involves a small Committee, including a Project Coordinator. It has proved most effective and economical.

The Monograph 22 Committee was established early in 1996, under the direction of Sandra Close, (Chairman of The AusIMM Publications Committee) with the Joint Editors, The AusIMM Publications Manager and the Project Coordinator. Overall parameters and criteria for papers were determined and a detailed Guide to Authors and Standard Operating Procedures were developed, to ensure a streamlined process. Over 300 companies were then invited to submit papers if their deposits met the criteria. The invitation was repeated in The AusIMM Bulletin and The Australian Geologist, to ensure that the volume’s coverage was comprehensive.
