Magmatic water. Magmatic water or juvenile water is water that exists within, and in equilibrium with, a magma or waterrich volatile fluids that are derived from a magma. This magmatic water is released to the atmosphere during a volcanic eruption. Magmatic water may also be released as hydrothermal fluids during the late stagessystem very close to the loci of magmatic and fumarolic activity (NSF well in Figure 1b and hereinafter in text; locally referred to as Keller well). We compare the well water chemical and isotopic compositions with new and existing fumarole chemistry data to magmatic water system

Oct 13, 2006  The Ladolam hydrothermal system, on Lihir Island, Papua New Guinea, hosts one of the youngest and largest gold deposits in the world. Several deep (more than 1 kilometer) geothermal wells were drilled beneath the ore bodies to extract water at 275C and to facilitate openpit mining. Using a titanium downhole sampler, we determined that the deep geothermal brine of magmatic origin

Similarly, most of the quartz samples yield 18 O values of the fluid from 6. 4 to 8. 9 at the JingxiYelmand deposit (Fig. 7A), which is also consistent with magmatic water in origin. There are many examples showing that epithermal deposits can have a magmatic dominated origin such as the modern Lihir system ( Simmons and Brown, 2006 ). Sep 03, 2018  The systems unique gas compositions are controlled by magmatic water content and redox state, as shown by a compilation of volcanic gas and aerosol metal data. magmatic water system (9) describes to a rst approximation the deep mixing process involving seawater and magmatic water, which occurs in the roots of the hydrothermalmagmatic system of Nisyros (Marini et al. , 2002; Brombach et al. , 2003; Marini and Fiebig, 2005).

Cooling of magmas. There are two known processes by which magma changes: by volcanic eruption (to become lava ), or by crystallization within the crust or mantle to form a pluton. In both cases most of the magma eventually cools and forms igneous rocks. When magma cools it magmatic water system Magmatic water topic.

Groundwater pumping at Goldstrike has resulted in 520 m of drawdown around the mine site. Most of the water pumped at the mine has been returned to the same hydrologic basin. Extensive monitoring program, assisted by modern satellite technology and by Magmatic water was tied up in biotite and hornblende which had formed earlier. Common sources of fluids that typically form ore deposits are magmatic water, meteoric (rain) water, sea water, and connate or formation water. The minerals in Table 3 were deposited by an ore fluid, which was dominantly magmatic water,
