This study identifies the geological origins of the “black granite” headstones of 149 Titanic victims in Halifax, Nova Scotia. Researchers used forensic petrology techniques to trace these gabbroic headstones to the Charles Hanson quarry in Bocabec, New Brunswick. Through detailed analyses of mineralogy, geochemistry, and radiometric dating, the team established a match, demonstrating how forensic geology can help trace historical artefacts to specific sources.
