“…The association of Te and Au is typically encountered in magmatic, metamorphic and hydrothermal deposits (Cook and Ciobanu, ; Ciobanu et al ., ). Similarly, the association of Hg and Au is one normally associated with magmatic systems, metamorphic rocks and placer deposits derived from these rocks (Healy and Petruk, ; Naumov and Osovetsky, ). The data reported here show that temperature is not a constraint and that where Te and/or Hg are available, regardless of temperature, Au may be linked to them.…”

Low‐temperature concentration of tellurium and gold in continental red bed successions

There is very little understanding of tellurium (Te) distribution and behaviour in sedimentary rocks. A suite of 15 samples of reduction spheroids (centimetre-scale pale spheroids in otherwise red rock), including samples from eight localities in Triassic red beds across the British Isles, were mapped for Te using Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry. Almost all showed enrichment in Te in the cores of the spheroids relative to background red bed concentrations, by up to four orders of magnitude. Some were also enriched over background in gold and/or mercury. In one case, discrete telluride minerals were recorded. The data show that Te is mobile and can be concentrated in low-temperature sedimentary environments, controlled by redox variations. The consistency in enrichment across widely separate localities implies that the enrichment is a normal aspect of red bed diagenesis and so likely to be controlled by a ubiquitous process, such as microbial activity.

“…There is native and technogetic mercury in the wastes, which is dissolved under +20℃ and interacts with gold easily. Due to the of influence of mercury, nano-and micro-gold phases are aggregated, and therefore conglomerates of gold (to several mm) can be formed [10]. For example, as the result of our study of gold from Iz and Tura Rivers we obtained various forms of gold and mercury compounds of different compositions.…”

Supergene gold transformation in technogenic mineral formations

This article is about the research on gold obtained from mine wastes and other technogenic mineral formations. The authors investigated how solid phases of gold in supergene zone transform from various deposits. Results show the following supergene gold transformations by various physical, chemical, biological and mechanical processes occurring in the wastes. Transformations result in changes in morphology and chemical composition, and special redistribution of gold in wastes.

Authigenic gold occurs in Devono-Carboniferous red beds in northern Britain. Red beds exhibit concentrations of gold and pathfinder elements for gold mineralization including tellurium and mercury, at redox boundaries. Detailed studies of samples from Millport, Isle of Cumbrae, Firth of Clyde, show particles of native gold up to 10 µm size, typically with less than 15 wt% silver. Their context indicates that the gold was concentrated during diagenesis, in rocks that had not experienced regional temperatures above 100°C. These occurrences add to other evidence of a role for red beds in the genesis of gold mineralization.
