Metamorphism Type: Regional

Dec 07, 2005 (A Wilson) - The showing straddles the boundaries between the Northern and Southern Domains of the Goudreau Lake Deformation Zone. The GLDZ is up to 4.5 km in width and strikes in a gentle sigmoid-form for at least 30 km, subparallel to the stratigraphy and the regional foliation. In the immediate Goudreau-Lochalsh area, the GLDZ is coincident with a major contact between Cycle 2 and Cycle 3 volcanics. There is a strong structural control of the gold-bearing quartz veins systms within each of the 070-075 striking high-string zones within the deformation zone. There are several parallel high-strin zones within the Webb Lake Stock. These zones are parallel to the regional schistosity in the area. Individual quartz veins are localized within narrow, secondary, brittle-ductile shear fractures.

Dec 07, 2005 (A Wilson) - The Webb Lake stock has been termed a quartz porphyry, quartz-felspar porphyry, quartz diorite, granite-monzonite porphyry, granodiorite or trondhjemite. The intrusion has undergone extensive deformation and metasomatic alteration and is highly sheared. The stock has intruded intermediate to mafic metavolcanic rocks that are locally cut by gold-bearing quartz veins.
