Researchers from China University of Geosciences Beijing Report New Studies and Findings in the Area of Ore Geology (Geological and Geochemical Characteristics of the Wulong Gold Deposit, Liaodong Peninsula: Implications for Gold Mineralization)

摘要

2022 JUL 1 (VerticalNews) – By a News Reporter-Staff News Editor at Mining & Minerals – Investigators discuss new findings in Geology - Ore Geology. According to news reporting out of Beijing, People’s Republic of China, by VerticalNews editors, research stated, “As a typical hydrothermal vein-type gold deposit in the eastern Liaodong Peninsula, northeast of North China Craton, the Wulong gold deposit is associated with the Jurassic gneissic two-mica granites with gold reserves over 80 t. In this paper, the gold precipitation and enrichment mechanism of the Wulong deposit is investigated by studying the morphological structure and geochemical characteristics of pyrite. Pyrites are divided into four types based on their microstructural characteristics: Py1 is represented by disseminated pyrite, which was developed in granites; Py2a is dominated by porous pyrite, which developed in the early quartz-pyrite vein; Py2b commonly wraps Py2a, distinguished from Py2a by its ‘smooth ‘ surface, and developed in the quartzpolymetallic sulfide stage; Py3 was observed in quartz-calcite-fluorite stage.” Financial support for this research came from National Key Research and Development Program of China.
