Scientists in Yakutia detected fluids from gold deposits
Title: Unveiling the Mystery Behind Large Gold Deposits: The Case of Konduyak, Russia 🇷🇺
Hey Buddy!
Scientists from the Institute of Geology and Mineralogy named after V.S. Soболеv Siberian Branch of the Russian Academy of Sciences in Novosibirsk and the Siberian Federal University in Krasnoyarsk have been delving into the secrets of the Konduyak gold deposit in Krasnoyarsk Krai. These findings could shed light on the processes that lead to the formation of large gold deposits.
Let's get this gold diggin'!
These scientists were particularly interested in the composition of fluids found on the Konduyak gold deposit. Fluids—the microscopic pockets containing liquid and gas that form within minerals during their creation—can provide crucial information about the conditions under which these minerals and their precious metal contents were formed.
The chemical makeup of these fluid pockets can reveal the temperature, pressure, and redox conditions that existed as the minerals formed, allowing geologists to gain insights into the formation of gold deposits. However, understanding how the specific components within a fluid's makeup contribute to gold deposition and the formation of large gold deposits has remained elusive.
Diggin' Deeper
In an effort to unravel these mysteries, the researchers collected ten samples from the Konduyak gold deposit and analyzed them using modern methods. One such method—Raman spectroscopy—helped them determine the primary components of fluid pockets. Their investigation revealed that water, carbon dioxide, methane, and nitrogen were the most prevalent components in these pockets.
To better understand the composition of the pockets, the team also employed gas chromatography-mass spectrometry, a highly sensitive method that separates the components of a mixture based on their chemical properties. This enhanced analysis uncovered between 232 and 302 different compounds in each sample, in addition to water and carbon dioxide. The team found that other components, including hydrocarbons, sulfur-containing, and nitrogen-containing compounds, were also present in the fluid pockets.
"Earlier research has shown that these components play a crucial role in the transportation and deposition of gold, as they can form gold complexes, facilitating its migration through rock formations. As conditions change, such as temperature or pressure, these complexes break down, and gold precipitates out of solution, forming deposits," explain the researchers.
Leading the Charge
The project leader, Dr. Elena Shaparenko, a Candidate of Geological and Mineralogical Sciences and a researcher at the Thermobarogeochemistry Laboratory of the Institute of Geology and Mineralogy named after V.S. Soболеv Siberian Branch of the Russian Academy of Sciences, stressed the importance of understanding a mineral-forming fluid's composition for developing and refining geological and genetic models of mineral deposits. These models are utilized during the search for new and the examination of existing mineral resources.
"The study of mineral-forming fluid composition is essential for expanding the mineral resource base of the country. In the future, we plan to compile data on the parameters of mineral-forming fluids from over a dozen gold deposits in the Enisei Range and develop a model of the fluid regime that governs the formation of large-scale Enisei gold deposit provinces," she said.
The researchers also noted that fluid pockets at Konduyak were similar in composition to those found in other gold deposits in the Krasnoyarsk region. This suggests that the formation of gold deposits in the region may be part of a larger, coordinated geological system.
