GOLD IN ORES OF THE VERNINSKOE DEPOSIT (IRKUTSK REGION)

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2023
The relevance of the research is caused by poor knowledge of the material composition of the ores of the Verninskoe deposit. The data obtained are an important tool not only for clarifying the predictive and prospecting criteria for gold ore deposits of carbonaceous black shale strata, but also will help increase gold extraction from ore by adjusting ...

Gold‐Related Sulfide Mineralization and Ore Genesis of the Penjom Gold Deposit, Pahang, Malaysia [PDF]

open access: yesResource Geology, 2007
AbstractThe Penjom gold deposit lies on the eastern side of the Raub‐Bentong Suture line within the Central Belt of Permo‐Triassic rocks, near Kuala Lipis, Pahang, Malaysia. The geology of the deposit is dominated by a sequence of fine‐ to coarse‐grained rhyolitic to rhyodacitic tuff, tuff‐breccia and a minor rhyolitic–rhyodacitic volcanic series ...

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

open access: yesGeological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

A mineral composition of gold-bearing quartz-sericite metasomatites of Ozernoe and Kutyn deposits (Khabarovsk krai) of low-sulphide gold-quartz type

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2015
Today we have a huge problem with prospecting new gold-ore deposits and its estimation on deep horizonts, especially in the closed territory. Often we used “analogy” method to make a decision.

A black shale protolith for gold-tellurium mineralisation in the Dalradian Supergroup (Neoproterozoic) of Britain and Ireland [PDF]

open access: yes, 2017
The Dalradian Supergroup of Britain and Ireland is mineralised by gold-tellurium vein deposits. The host succession includes carbonaceous, pyritic shales (pelites) which were a source of trace elements, including gold and tellurium.

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

open access: yesGeological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Clinical Outcome Assessments in Parkinson's Disease: A Scoping Review of Current Rating Scales and Future Needs

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Clinical outcome assessments (COAs) are essential for evaluating symptom severity, treatment response, and disease progression in Parkinson's disease (PD). As clinical knowledge evolves, it is necessary to revisit the recommendation status on the COAs to ensure their continued relevance and validity. Objectives To provide an updated
