Evidence for the structurally controlled deposition of hot spring and fumarolic minerals at the Humboldt House, Nevada
Abstract The presence of a geothermal reservoir at
The presence of a geothermal reservoir at the Humboldt House, NV has been known due to the outcrops of hotspring and fumarolic deposits in the Humboldt River Valley. Formally mapped in 1983, their distribution does not suggest a structurally controlled deposition, so the mechanism of deposition is unknown. In order to map the complete distribution of hotspring and fumarole deposits at the Humboldt House, NV and to constrain the mechanism of deposition we applied remote sensing techniques linked with field observations. HyMap hyperspectral imagery was acquired at the Rye Patch-Humboldt House geothermal district for its ability to detect hydrothermally associated minerals due to its high spatial and spectral resolution. Using the HyMap imagery, mineral distribution maps were made for the Humboldt House area, and the results were validated in the field using a handheld spectrometer. Remote sensing methods revealed a more abundant distribution of hot spring and fumarole deposits in the Humboldt River Valley, and their N-NE trending linear distribution implies a structurally controlled deposition. Overlying all Lake Lahontan deposits, the hot spring outcrops can be constrained to Holocene in age, and represent the most recent faulting expressions in the Rye Patch-Humboldt House geothermal district. The fault conduits that initially brought geothermal fluids to the surface have since sealed and the hot springs are no longer active.
