Pyrrhotite (Po) from five orebodies (, , , , and OB) in the Copper Cliff Offset Dike (CCOD) at Sudbury, Ontario was studied using powder X-ray diffraction data and Rietveld. Slaught WH () A petrographic study of the copper cliff offset in the Sudbury district. M Sc Thesis, McGill Univ (unpublished) Google ScholarCited by: 2. The copper-uickel sulfide ores of the Sudbury basin are associated with sublayer intrusions along the outer margin of, and as outward radiating offset dykes from, the main Sudbury Irruptive. The offset dikes host major Ni-Cu-PGE deposits, with the radial Copper Cliff dike hosting ~15 percent of the known Sudbury ore. The anisotropy of magnetic susceptibility of the Copper Cliff dike was studied to determine the nature of the fabrics that developed during emplacement of the quartz diorite and the associated sulfide by: 9.

Complex (Ga) and the Copper Cliff Offset dyke has been traced to within about 6km northeast of the property, south of Kelly Lake. Offset dyke rock (quartz diorite with minor sulphide mineralization) has also been confirmed in the area of Page Lake, located about km southeast of the property.
