Exploration Activity: Surface Water Sampling At Raft River Geothermal Area (1973)
|Exploration Activity Details|
|Location||Raft River Geothermal Area|
|Exploration Technique||Surface Water Sampling|
At least 380 hot springs and wells are known to occur throughout the central and southern parts of Idaho.
One hundred twenty-four of 380 hot springs and wells in the central and southern parts of Idaho were inventoried as a part of the study reported on herein. At the spring vents and wells visited, the thermal waters flow from rocks ranging in age from Precambrian to Holocene and from a wide range of rock types-igneous, metamorphic, and both consolidated and unconsolidated sediments. Twenty-eight of the sites visited occur on or near fault zones while a greater number were thought to be related to faulting. Measured water temperatures at the 124 wells and springs inventoried ranged from 12 to 930C and averaged 500C. Estimated aquifer temperatures, calculated using the silica and the sodium-potassium-calcium geochemical thermometers, range from 5 to 3700C and averaged 1100C. Estimated aquifer temperatures in excess of 1400C were found at 42 sites.
