AbstractIn this paper, we introduce a new method to include structural geological information into the stochastic inversion of potential field data. The inversion method is based on a geostatistical approach with ability to add gradient information. The method considers geological interfaces and planar orientation data such as stratification or foliation estimated from drill holes or seismic interpretation. Application to a synthetic gravity model of a folded high-density layer demonstrate that the constrained stochastic inversion method significantly improves the recovered model. The method is also applied on a case study in the Lalor area in Manitoba, Canada in order to characterize the deposit and host environment by integrating seismic information and borehole data.
