Abstract
Geophysical inversions play an important role in today’s mining exploration. Accompanying the availability of multiple types of geophysical data collected over the same study area is the need of jointly inverting them all and generating a common earth model, as opposed to the common practice of separately and independently inverting each data set. We investigate in this paper the use of multi-domain joint clustering inversion of magnetic and IP data in the context of sulfide deposit exploration. We compare the recovered models from joint inversion with those from L2-norm inversion, L1-norm inversion and separate clustering inversion of single data type, and demonstrate that only the jointly inverted models can reliably represent the complex geological structures in such a setting.
