The northern part of the Siberian platform and the Taimyr epi-platformal fold system, which are separated by the Yeneseisko-Khatangsky Rift, belong to the Precambrian North Asian superplatform . The major metallogenic features are deposits of the North Siberian nickel-bearing area. The mineralization of the Noril’sk region, which is attributed to evolution of a mantle picritoidal melt, is a unique phenomenon, which has no analogues within the region. The ultramafic/mafic products of the nickel-bearing magmatism of the Noril’sk region are closely associated with trap and later magmatism which is spatially and genetically connected with various deposits that are associated with specific magmatic complexes.
The present interpretation of the deep structure, evolution of magmatism and endogenic ore formation of the region is based on results of recent complex geological and geophysical [1, 15, 22, 45, 109, 1l7, 128, 138] and metallogenic [20, 33, 37, 60, 85, 106, 135] studies.
The northern part of the Siberian platform, as well as the Southern Taimyr fold belt, being the relict constituent elements of the northern Asian craton, have developed as a result of multiple, but mainly late Hercynian, autonomous activity, as seen in the intense rifting. The North Asian craton extended from the Ural belt to Verkhoyanya, and from the Northzemelsky archipelago up to the Sayan (mountains). In Archean and Early Proterozoic times this vast terrain was a fold-belt which was later split by aulacogenes into huge blocks that developed during the Riphean and Paleozoic as a unique, gigantic structure.

The Noril’sk volume is a valuable contribution to the economic geology profession. The translation which is a very literal one from the Russian original, has been ‘donated’ to the Society of Economic Geologists by Falconbridge and Inco. This is the first special publication for the Society. We have two successful series, Reviews in Economic Geology and our Guidebook series. When we were offered this translation we initiated this special publication series. It is hoped that we will continue to pursue and publish other monographs of direct economic interest for our members and the economic geology community at large.
This volume and the accompanying figures (maps), tables and plates presents an excellent overview of the Noril’sk area and the mineralization specific to this region. Considerable awareness of the Noril’sk area has been available through various translations of Russian literature and ever increasing opportunities for western world geoscientists to visit the region. The Society is proud to have this opportunity to provide this comprehensive volume to economic geoscientists.
Many individuals contributed their time, expertise and support. We would like to acknowledge A.J. Naldrett for his efforts in obtaining this translation from Inco and Falconbridge on our behalf. He was also our liaison with the original authors and was very supportive throughout the editing process. Falconbridge initiated the translation and G. Rylkova was contracted to produce a literal translation and we chose to substitute, or identify, a few nonfamiliar Russian terms with equivalent English language terms. However, the substance of the translation has not been changed. The editing concentrated on consistency, accuracy and limited grammatical re-interpretation. A location map and a stratigraphic section were added to the introduction. Suggestions for editing consistency were gratefully received from A. Craigie and R. Horn.
Additional support for production and distribution was received from T. Thompson, J. Robertson, K. Clark.
All figures, tables and plates were redrafted with their interpreted legends by Inco. W. Saftic and W. Peredery provided additional suggestions for drafting format and continuity. Inco and Falconbridge shared all drafting costs and donated this service to the Society of Economic Geologists as well as the translated text. P. Lightfoot gave permission to include the location map and the stratigraphic section in the introduction.
The cover design was produced by C. Podashinsky and the WP formatting was contracted to Keystrokes Business Support Services. Production and printing of the volume was contracted to Citizen Printing Co. Inc. of Fort Collins.
