Emergence Setting and Hydrology
Emerges from a mineralized mound, frequently at magmatic or fault systems.
For Example: Montezuma Well, AZ
Mound-form springs emerge from precipitate (typically carbonate) mounds or peat mounds. Common in the central Australia's Great Artesian Basin, they also occur in Western Australia and North America (Knott and Jasinska 1998, Springer et al. 2008). Mound springs formed from travertine are often thermal, found along active magmatic or fault systems. "Black smokers" on the ocean floor may be extremely hot, discharging large amounts of carbon dioxide from deep in the earth (Crossey et al. 2008). Due to their unique water chemistry, and sometimes due to their isolation in arid regions, these springs often support high biodiversity and endemism (Knott and Jasinska 1998; Blinn 2008).
