Forensic geology


Forensic geology is the study of evidence relating to minerals, oil, petroleum, and other materials found in the Earth, used to answer questions raised by the legal system.
In 1975, Ray Murray and fellow Rutgers University professor John Tedrow published Forensic Geology.
More recently, in 2008, Alastair Ruffell and Jennifer McKinley, both of Queen's University Belfast, UK, published Geoforensics a book that focuses more on the use of geomorphology and geophysics for searches. In 2012, Elisa Bergslien, at SUNY Buffalo State, published a general textbook on the topic, An Introduction to Forensic Geoscience.

Early use of forensic geology

According to Murray, forensic geology began with Sherlock Holmes writer, Sir Arthur Conan Doyle. The character Sherlock Holmes claimed to be able to identify where an individual had been by various methods, including his having memorized the exposed geology of London to such a degree that detecting certain clays on a person's shoe would give away a locale. Georg Popp, of Frankfurt, Germany, may have been the first to use soil analysis for linking suspects to a crime scene. In 1891, Hans Gross used microscopic analysis of soils and other materials from a suspect's shoes to link him to the crime scene.
