Lode Gold Deposits (Veins of Gold in Rock & Gold Ore) Veins of gold in rocks and gold ore under the ground (and sometimes above the ground) are called lode deposits.

fourth largest gold producer after South Africa, Australia and the CIS. Much of this gold is being produced from sediment-hosted disseminated gold deposits. Many geologists call these deposits Carlin-type (Berger and Bagby, ) after the mine of the same name in Nevada. The Carlin mine was discovered in by Newmont Exploration Limited. Geologically, most of the primary gold deposits are located within the pre-Hercynian basement areas, mainly consisting of highly metamorphic or magmatic rocks. Placer gold deposits are known from paleo-fluviatile sediments of upper Paleozoic age, Cretaceous age and quite frequently in Tertiary rocks, mainly in the foreland of the by: 8.

“Gold Deposits of the CIS” represents the first comprehensive study in English of the gold and gold-silver deposits and their resources of the former Soviet Union. The book includes: (1) a history of gold exploration and mining in this region from ancient times, (2) the contemporary classification of the deposits, (3) a detailed description.
The book begins with two brief introductory chapters, one on the history of exploration and mining, and the second describing the complex classification system of gold deposits in the CIS.
The classification Gold deposits of the CIS book is based on gold ore host rocks and is used to subdivide the remainder of the book.
