International Scientific-Technical Conference «Geotechnics Fundamentals and Applications in Construction: New Materials, Structures, Technologies and Calculations» (GFAC 2019) was held by Saint Petersburg State University of Architecture and Civil Engineering 6–8 February 2019. Its aim was devoted to enable the interactive exchange of state-of-the-art knowledge and to bring together leading academic scientists, researchers and scholars in the domain of interest from around the world. The Conference provided a unique forum for prominent researchers and young talented specialists to present the latest research findings, emerging technologies and directions in geotechnics, soil mechanics, foundation engineering and all related construction spheres <...>

Giant (and super-giant) metallic deposits are defined as those that store the trace metal (and some major metal like Fe, Al) equivalent in 1011 (1012) tons of continental crust in Clarke (mean crust content) concentration. Deposits of metallic ores that have very contrasting Clarke values (like Fe, Cu and Au) can be compared on geochemical basis, with political-economic and technologic factors minimized. Under these terms, there are now 1171 giant and 137 supergiant accumulations of 37 metals worldwide, contained in 915 deposits, as several deposits have two or more giant metal accumulations (Olympic Dam has 5).

As explained in Preface, this book is a selfcontained member of a broader knowledge system on the world's mineral deposits and their settings I have been developing and experimenting with for more than 40 years. It is a product of global firsthand information gathering in the field and "data mining" from the literature, followed by sorting and organization into interrelated sets searchable and accessible by the rapidly evolving techniques of modern information technology.
