【 摘 要 】

The extinct Haveri Au-Cu deposit is located within mafic metalavas and mafic/ intermediate banded rocks of the Haveri Formation, in the western part of the Paleoproterozoic Tampere Schist Belt. The sulfide-bearing banded rocks display a large E-W trending fold structure in magnetic and electromagnetic maps. Field evidence suggest that the Au-Cu deposit is in a F1/F2 fold interferrence pattern in the western core of the large fold. The ore-forming elements concentrated into the F1 fold closure during D1 deformation. Sulfide-bearing fractures subparallel to S2 spaced cleavage indicate slight remobilization during D1.
