GOLD IN ORES OF THE VERNINSKOE DEPOSIT (IRKUTSK REGION)

Известия 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]

Resource 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 ...

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

Geological 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 ...

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

Известия 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.

Contrasting Surficial Composition of Native Gold from Two Different Types of Gold Ore Deposits [PDF]

Minerals, 2017
Native gold grains sampled at two different gold ore deposits in Eastern Russia have been studied by the techniques of electron spectroscopy (X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES)), electron microprobe analysis (EMPA), and scanning electron microscopy with energy dispersive X-ray spectrometry (SEM-EDX).

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

Movement 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
