Challenging the ambiguity in geophysical data interpretation
EF 2014-15
Résumé
It is important to continue efforts to develop the mineral resources in mining areas in order to use the oldinfrastructure and avoid disturb the environment; Falco Resources is thus interested in the largely unexploredarea to the west of the Flavrian pluton in the southern Abitibi greenstone belt. According to few drill holes theyestimated that the stratigraphy near the surface is sub-horizontal, where potentially host multiple horizons thatare favorable for volcanogenic massive sulfide (VMS) type of mineralization. There are several gold showingsin the area, and the litho-geochemical signature is similar to that of host rocks of the Horne deposit. However,the present occurrence of stratigraphy sequence and their contact with gabbro dikes (diabase) or intrusions atthe depth are poorly known. A plausible structural geology 3D model from geophysical data interpretationwould help Falco Resources to better understand the geological context and evaluate the mining developmentpotential.From geophysical observation we can recover a physical property distribution underground; further to find outits geological implication. The key question is how much similarity or consistency between geophysical modeland that of geology? To solve this problem we need the knowledge of petrophysics to constrain geophysicaldata interpretations, we need also the team work with geologists to integrate known geological information intothe geophysical data inversion procedure. The proposed research project will consist of two main parts: 1)discover the intrinsic link between the variability in geology and characteristics associated with geophysicalresponse; 2) combine data processing, forward modeling and constrained 3D inversion of geophysical data, todefine the present occurrence of stratigraphy sequence; to evaluate if there are deep seated fault zones whichallowed ore-bearing fluids to circuit; as well the spatial relationship between the stratigraphy sequence andintrusions.
