Gold mineralization associated with Emeishan basaltic
A number of gold deposits are newly discovered in the Lianhuashan ore field, southwestern Guizhou Province, China. The gold orebodies are restricted to the Emeishan basaltic rocks and the interlayer fractures between the Emeishan basaltic We documented occurrences of native copper (Cu), silver (Ag), and gold (Au) in a pāhoehoe flow from Kīlauea volcano (Hawaii, USA), an aʻā flow from Mauna Loa volcano (Hawaii), and a midoceanic-...Vapor transport of silver and gold in basaltic lava flows

Basalt
Basalt (UK: / ˈ b æ s ɔː l t,-əl t /; US: / b ə ˈ s ɔː l t, ˈ b eɪ s ɔː l t /) is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at In the gold-bearing region of Northern Sonora, Mexico, the gold-veins are chiefly in or closely associated with granitic and plutonic rocks. The veins of El Grupo concession, about 100 miles southeast of Tucson, Arizona, traverse a fine-grained granite, and hear both gold and silver. A dioritic rock at El Plomo, in the same State, appears to Gold in Granite & Plutonic Rocks 911 Metallurgist

Basalt: Igneous Rock Pictures, Definition, Uses & More
Basalt is also an abundant rock on the Moon. Much of the Moon's surface is underlain by basaltic lava flows and flood basalts. These areas of the Moon are known as "lunar maria." Large areas of the Moon have been resurfaced by extensive basalt flows which may have been triggered by major impact events. The ages of lunar maria can be estimatedGold mineralization associated with Emeishan basaltic rocks: Mineralogical, Ore-forming process of the Huijiabao gold district, southwestern Guizhou Province, China: The basalt-hosted and sediment-hosted Au deposits in Dian-Qian-Gui area formed in response to the same widespread metallogenic event.Gold mineralization associated with Emeishan basaltic rocks

Mare basalts, being young by lunar standards, are, as a rule, far less battered by impact processes than highland rocks; they are also generally closer in composition to their parent melts (i.e., the proportion of cumulates is far higher among highland rocks).Basalt an overview ScienceDirect Topics

Genesis of the Xiaotongchang basalt-hosted copper deposit in
Distributing all over the world, the basalt-hosted copper deposits are mostly associated with mantle plume, such as the Keweenaw-type copper deposits in America, basalt-hosted copper deposits in SW China (Kirkham et al., 1984, Zhu et al., 2002b, Zhu, 2003, Symons and Kawasaki, 2019) and the Brazil native copper These ‘gold-only’ deposits are thought to have formed from hot, aqueous fluids rich in carbon dioxide 2, but only minor significance has been attached to the role of the CO 2 in the process ofRole of CO2 in the formation of gold deposits Nature
