Exploration Activity: Gas Flux Sampling At Lualualei Valley Area (Thomas, 1986)
|Exploration Activity Details|
|Location||Lualualei Valley Area|
|Exploration Technique||Gas Flux Sampling|
Soil mercury and radon emanation surveys were performed over much of the accessible surface of Lualualei Valley (Cox and Thomas, 1979). The results of these surveys (Figs 7 and 8) delineated several areas in which soil mercury concentrations or radon emanation rates were substantially above normal background values. Some of these areas were apparently coincident with the mapped fracture systems associated with the caldera boundaries. However, some anomalous zones were identified well outside these areas. These results were generally interpreted to suggest the presence of at least low-level thermal effects associated with the caldera boundaries; however, it is apparent that other non-thermal influences are being detected as well.
