This paper describes a reworking of the FTG and magnetic data to map detailed lineament patterns followed by joint interpretation of an inversion over known VMS deposits. The results lead to an increased understanding...

These maps show an E-W lineament identifies a strike-slip fault, not observed in P-wave depth slices. These results...

The results have been correlated with an image log to confirm the nature and fill of the seismic lineaments. Understanding the variation in length and intensity of those events is critical to understanding...
