Exploration Activity: Core Holes At Valles Caldera - Redondo Geothermal Area (Fawcett, Et Al., 2007)
|Exploration Activity Details|
|Location||Valles Caldera - Redondo Geothermal Area|
|Exploration Technique||Core Holes|
|Activity Date||2004 - 2004|
An additional core hole, VC-3, was completed in 2004 as part of the GLAD5 project to investigate major climatic changes and glacial/interglacial cycles recorded in lacustrine sediments below Valle Grande. While the findings of this shallow core hole are significant with respect to paleoclimate research, they pose little relevance to the exploration for geothermal resources.
The objective of VC-3 was to sample a long lacustrine record below Valle Grande to be used for paleoclimate research. The well was drilled to a depth of 81.4 m with nearly 100% core recovery of lacustrine mud and silt. Recovery of gravels in the top and bottom sections of the hole were comparatively poor.
