The first evidence of native copper in the volcanic rocks in the northern part of the Siberian platform was published in the classic work of V.I. Vernadsky “An Opus on Descriptive Mineralogy”. In 1945, G.G. Moor, while analyzing scarce data on native copper in the lava fields of the area of the Siberian traps concluded that there was a genetic correlation between this mineralization and deposits located in the area of the Upper Great Lakes Michigan of the United States of America.
Many showings of native copper have been recorded since _ the start of the 1950’s, due to the development of systematic geological mapping and prospecting in the Noril’sk region, and in the northwestern part of the Siberian platform in general. Most of these occur in the upper part of the sequence of tuffs and lavas. Copper is concentrated essentially in the amygdular basalts and lava breccias, rarely in massive portions of the basalt sequence. Disseminated copper has been found in tuffs and limestones which occur in tuffaceous horizons of the Triassic basalts, and sometimes in carbonate veins.
Important new data on the distribution of the copper mineralization were obtained as a result of prospecting along the northern slopes of the Kharayelakh mountains [36, 43]. Several copper-bearing horizons were recognized in the volcanics, including the elongate, stratiform, Arylakhsky deposit, which contains copper mineralization throughout. The distribution of the copper is governed by lithology and stratigraphy, and most of the showings are associated with carbonate horizons which occupy several

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.
