Don Grybeck’s simplified Craig / Dixon-Entrance Geology Map. As you can see a number of different geologic units were mapped but the mapping shows some inconsistencies.
The northern boundary of the olive green Descon rocks with the purple-gray Wales Group rocks is not well known, and this is important if we are searching for Proterozoic rocks that could host a VMS deposit.
The felsic to mafic volcanic and sedimentary rocks of the Karheen Formation also have potential for VMS mineralization. In map units characterized by small scale lithologic variability, we can look for areas with alteration signatures or small areas with geophysically anomalous signatures.
The area labeled SOsv is a time correlative unit to the Descon formation to the north.
