1900--1967
Stanley Davidson-- geophysical techniques applied to mining. He was big on this.
He was an inventor. Pushed the EM devices: Airborne Magnetometers.
at Falconbridge.
Geophysics: Magnets and that sort of thing--electrical fields.
Different from geology.
1900. Montreal-- PhD Harvard. Science.
1923 -- Started as surveyor/engineer for Mond Nickel.
1927--32: Mexico--experimented with geophysics.
1932---Went to Inco and Sudbury. Then moved over with TL to Falconbridge.
Inventor:
"It was in the early 1940s that he and a Falconbridge mine electrician built an electromagnetic device based on a description in a McGill University textbook. It successfully distinguished between magnetic anomalies from disseminated magnetite and anomalies from conductive sulphides. This resulted in the discovery of several Sudbury-area orebodies. He further refined this apparatus while consulting with Sherritt Gordon. This device aided in the discovery of the Lynn Lake deposits and later was used extensively by Sherritt."
Sherritt Gordon. Started with EM. then Airborne EM.
Is that the same as a magnetometer? In any case this was the FIRST airborne EM.
Used to discover Heath Steele Copper-lead-zinc in NB
and Thompson nickel in MB.
