Surface distributed acoustic sensing for mineral exploration.

ABSTRACT: As a receiver array for active-source seismic studies, the use of distributed acoustic sensing (DAS) technology is well established for vertical seismic profiling. However, given the sensitivity of fiber-optic cables, successful and cost-effective surface array studies in reflection seismology and for mineral exploration are still missing. In a feasibility study, we investigate the performance of surface DAS technology for mineral exploration in a hardrock environment. The target is an iron-oxide deposit located in the Bergslagen district in central Sweden. The fiber-optic cable was laid on the surface above the dipping mineralization and covered with a few centimeters of gravel to increase its ground coupling. The data quality varies significantly along the fiber cable. Nonetheless, it is
