The Hadamengou deposit is the largest gold deposit in Inner Mongolia. However, given that the sources of ore-forming alkaline magmatic hydrothermal solutions and ore-controlling structures are still controversial, the theories behind the genesis of the deposit have been controversial. In this study, four controlled-source audio The Jiapigou gold metallogenic belt (JGMB), located in southeastern Huadian, southern Jilin Province, Northeast China, is not only an important gold cluster area in the eastern segment of the northern margin of the North China Craton (NCC), but also the main gold-producing area with proven gold reserves of more than 180 tons [] in China, in Construction and Application of a Knowledge Graph for Gold Deposits

The gold deposits that are hosted in the Archean metamorphic rock, have yet to be explored beyond Pinglidian gold deposit in the northwestern Jiaodong Peninsula, eastern China. This kind of gold deposit differs from those that are hosted in Mesozoic granitoids, showing good potential for the prospecting of auriferous quartz-vein gold Lode gold deposits are widespread in orogenic belts of various ages and are a valuable gold source, but their genesis remains debatable. The close relationship between native gold and quartz was considered a reason to search for acid-magmatic sources of heat and fluids (i.e., granite intrusions), while small gabbro bodies were often ignored.

Overview on Gold Deposits in Finland ScienceDirect

Gold deposits and occurrences in Finland, and the three major VMS-type base metal mines which have produced significant gold (Outokumpu, Pyhäsalmi, Vihanti). The deposit data are based on Eilu and Pankka (2009), Grönholm and Kärkkäinen (2012), Eilu and Niiranen (2013), and on reports referred to in these compilations. Geology is The maximum Au content in this deposit is comparable to the content in bonanza gold deposits . The first data on gold contents in marine ferromanganese deposits were obtained by R.S. Harris et al. for ferromanganese nodules of the Pacific, Atlantic, and Indian oceans. The results showed that Au content varies from 0.21 ppb to 8.28 ppb.Gold in Ferromanganese Deposits from the NW Pacific

Fluid and metal sources in the Fäboliden hypozonal orogenic gold

Gold has been one of the most sought-after commodities for thousands of years. The global historical production is estimated to be approximately 180,000 tons and about one-third of that gold comes from orogenic gold deposits (Frimmel 2008).Orogenic gold deposits are considered hydrothermal in character, having formed from gold-bearing Two main stages of formation of gold deposits are identified in the north-eastern part of the Fennoscandian Shield—Neoarchean (2.7–2.6 Ga) and Paleoproterozoic (1.92–1.74 Ga).
