Explore the Sudbury ore story: how igneous rocks helped shape a once-in-a-generation nickel and copper district.
This reprint presents Alfred E. Barlow’s focused study of how the Sudbury deposits relate to their surrounding gabbro and norite rocks, offering clear explanations of geological ideas and methods used in early 20th-century field work.
The book compiles field observations, map work, and interpretations that connect rock types, ore formation, and spatial patterns across the Sudbury district. It discusses how ore bodies formed at the margins of igneous intrusions and how modern ideas of magmatic differentiation inform our understanding of these rich deposits. The text is supported by detailed map sheets and mining geological plans that illustrate ore distribution and mine positioning."synopsis" may belong to another edition of this title.
