Book excerpt: "Precambrian Ore Deposits of the East European and Siberian Cratons" is a sequel to "Precambrian Geology of the USSR" published in 1993 (English edition), in which the main emphasis was on the stratigraphy, magmatism and metamorphism of Precambrian assemblages in both ancient cratons (East European and Siberian) as well as in Phanerozoic fold belts and mobile regions. Mineral deposits associated with Precambrian structures were mentioned only in passing, since space restrictions in the earlier work did not allow even a brief outline of major deposits. The present book fills that gap.
