TL;DR: The early enrichment of gold in arsenic-bearing syngenetic to diagenetic pyrite, within black shale facies of sedimentary basins, is proposed as a critical requirement for the later development of Carlin-style and orogenic gold deposits in sedimentary environments as discussed by the authors.

TL;DR: Sediment-hosted Pb-Zn deposits contain the world's greatest lead and zinc resources and dominate world production of these metals as discussed by the authors, however, these ores are divided into two broad subt)1Jes: Mississippi Valley type (MVT) and sedimentmy exhalative (SEDEX), despite the "exhalative" component inherent in the term SEDEX, in this manusclipt, direct evidence and direct evidence of an exhalite in the ore or alteration component is not essential for a deposit to be classified as SED

TL;DR: The Sukhoi Logite mine in eastern Siberia as mentioned in this paper contains about 30 million ounces of gold at an average grade of 2.0 g/t Au and is one of the largest known undeveloped gold resources.

TL;DR: In this paper, the authors present evidence and arguments that carbonaceous sedimentary rocks were a source for Au and As in sediment-hosted orogenic and Carlin-type gold deposits and develop a corresponding genetic model.

TL;DR: There is a wide range in variability of styles of Australian VHMS deposits including mounds, pipes, sheets, layered deposits, stacked deposits, stockwork and disseminated deposits, distal reworked deposits, and cyclic layered deposits.
