A meteoric water line can also be calculated for a given area, and used as a baseline within that area.

Meteoric water is the water derived from precipitation (snow and rain).

Once again the carbonates came into contact with meteoric water and this was responsible for yet another episode of leaching.

Meteoric water, water in the ground which originates from precipitation

This faulting provided a pathway for meteoric water to enter the coal seams.

Most groundwater is meteoric water.

At this point the rocks had been fractured and meteoric water could inoculate the system with methanogenic microbes.

If the magmatic gas traveling upward encounters meteoric water in an aquifer, steam is produced.

Latent magmatic heat can also cause meteoric waters to ascend as a vapour phase.

In some cases these have been found to be the result of interaction with meteoric water, suggesting that Vulcanian eruptions are partially hydrovolcanic.

Global meteoric water line

Supergene processes include the predominance of meteoric water circulation with concomitant oxidation and chemical weathering.

The porphyry mineralization further benefited from the dry climate that let them largely out of the disturbing actions of meteoric water.

The thermal springs in India's peninsular region are more related to the faults, which allow down circulation of meteoric water to considerable depths.

"Isotopic variations in meteoric waters".

Ascending hydrothermal fluids, magmatic or meteoric water

Secondary calcite may be deposited by supersaturated meteoric waters (groundwater that precipitates the material in caves).

However, isotopic studies of hydrothermal waters indicate that most bear the isotopic signature of meteoric water.

The meteoric water infiltrates to depths of a few kilometers where it is heated to at least 220 C by hot rock near geologically young intrusions.

This recharge is typically from rivers or meteoric water (precipitation) that percolates into the aquifer through overlying unsaturated materials.

The infiltrating meteoric water (i.e., rainwater) floats on top of higher density saline water intruding from the coastal margins.

Weathering related cyrilovite, lipscombite, and crandillite-group minerals were formed by percolating meteoric waters under increasing oxygen fugacity.

The Global Meteoric Water Line is an equation defined by the geochemist Harmon Craig

The descending meteoric waters oxidize the primary (hypogene) sulfide ore minerals and redistribute the metallic ore elements.

Chemically, it is a cadmium sulfide, and occurs as a bright yellow coating on sphalerite or siderite in vugs, deposited by meteoric waters.
