Trap Magmatism and Ore Formation in the Siberian Noril'sk Region, Volume 1: Trap Petrology

About this book

The basis of Trap Magmatism and Ore Formation in the Siberian Noril'sk Region is the petrographic and geochemical understanding of principal igneous rock types of the Noril'sk region, in order to demonstrate that these data provide unique and self-evident solutions to the problems of petrogenesis and mineralization. The results of the investigations are presented in two volumes: the first includes mainly text and the second contains illustrations (these can be bought together as a two-volume set)

In the first volume, the state of the main problems of the genesis of igneous rocks with reference to Traps and related ore deposits is discussed, as well as short petrological descriptions of igneous complexes in the region, the mineral and geochemical diversity of the rocks, and aspects of the differentiation of basaltic melts and mineralization are described. Taking into account the vast number of publications on the petrology of Traps of the Noril'sk region, primary attention in Trap Magmatism and Ore Formation in the Siberian Noril'sk Region is given to earlier unknown phenomena, as well as other aspects that are of great importance for solving genetic problems. Some exotic geologic targets such as the Mikchandinsky differentiated cover, the magnetite lava flow of the Putorana Plateau, the magmatogenic breccia of Kharaelakh and others are described in detail.
