Typomorphic Features and Source of Native Gold from the Sykhoi Log Area Placer Deposits, Bodaibo Gold-Bearing District, Siberia, Russia

چکیده

The Bodaibo gold-bearing district in the Lena gold province of Siberia is one largest and oldest placer provinces world. Approximately 1650 tons has been extracted from region. Precise studies on source these unique deposits are lacking still controversial. Native four different locations was gathered to investigate its morphology, chemical signatures, structure inclusions. Some data primary bedrock mineralization were obtained published literature. linear weathering crusts developed along zones disjunctive dislocations near Sukhoi Log deposit researched. If they coincided with low-grade veinlet-disseminated gold–quartz–sulphide small grain sizes, a supergene replacement known have occurred, accompanied by formation gold-rich rims an increase size, content purity gold. Such associated can be local eluvial–proluvial placers, while placers large valleys formed due low-sulphide gold–quartz lodes.

Gold Bearing Conglomerates in some Molasse Basins of Iran

This article lists a number of geological data on the conditions of formation of some major gold deposits in the conglomerates of the Earth's crust. We analyze the metallogenic, tectonic, stratigraphic and other factors controlling the formation of gold-bearing conglomerates in certain fields, such as the Witwatersrand (S. Africa) and Darwaz (Tajikistan). The following tectonic factors play the...

Hydrothermal Gold Mineralization and Some Features of Ore Mineral at Onzon-Kanbani Area, Central Myanmar

Onzon-Kanbani area is a western flank of Mogok Metamorphic Belt where gold mineralization is hosted as auriferous quartz-vein with epithermal low-sulphidation characters. Mineralization is closely associated with NE-SW trending fracture or shear zone probably related to the dextral movement of the Sagaing Fault system. Mineralization related hydrothermal alteration is developed as narrow zones ...

Metagenome Sequence of a Microbial Community from the Gold Mine Tailings in the Kuzbass Area, Russia

The metagenome of a microbial community of the sediments from a highly acidic iron-rich puddle at the tailings dump of the Komsomolskaya gold mine in the Kuzbass area, Siberia, Russia, was sequenced. Binning of contigs yielded a near-complete genome of the dominant bacterium, representing a novel deep lineage of Deltaproteobacteria.
