Abstract
Rocks and minerals are natural sources of radiation. For this reason, airborne gamma-ray spectrometry (AGRS) has been used for many applications such as geological mapping, environmental studies, mineral exploration, and mapping of lithologic units. As an alternative to the AGRS standard processing, we have developed a 2D inversion-based processing method that incorporates the aircraft height and replaces the sensitivity correction. In addition, the inclusion of positivity condition using a logarithmic barrier prevents unphysical negative values that may arise from steps in the standard processing. We present a comparative study between the standard AGRS processing and the inversion-based processing of AGRS data in the gold deposit-rich area of Mara Rosa Magmatic Arc, Brazil, and demonstrate the benefits of the new approach.
