Multi-Parameter Visualization of Petrophysical and Geochemical Data for Base Metal Exploration

A large petrophysical and geochemical dataset has been obtained from archived drill core for a base metal exploration project located north of the Bathurst Mining camp (New Brunswick, Canada). The integration of this large, heterogeneous dataset presents a unique opportunity for statistical analysis of correlating and visualising multi-parameter behaviour in a bi-modal felsic/mafic geological setting. Large variation in parameter distribution enables questioning the linkage between petrophysical and geochemical parameters. To better characterize mineralization and alteration zones, a statistical approach has been developed for interactive visualization of the contribution of each parameter to the exploration model. The integration of geophysical and geochemical datasets produced robust results for imaging wide-spread alteration zones and associated base metal mineralization.
