Emplazamiento y deformación de diques con morfología zig-zag en rocas bandeadas y foliadas

A rather common feature of dykes intruded in banded and/or foliated rocks is their non-planar shape. This study describes the characteristics of zig-zagging magmatic dykes that occur in the Rainy Lake area of the Canadian Archean shield. The dykes are formed by planar or curved segments of different...
