Discovery and Structure
The Temagami Magnetic Anomaly is egg shaped, 58 km (36 mi) long and 19 km (12 mi) wide. The central section has the greatest amplitude and an E-W strike. The western portion appears smoother in character while the eastern section is long and narrow. With an areal extent of 50 x 15 km, the Temagami Magnetic Anomaly reaches a magnitude of approximately 10,000 nanoteslas making it one of the largest positive anomalies in North America. It was discovered by a magnetic survey and a gravity survey.
The Temagami Magnetic Anomaly has striking similarities to the nearby Sudbury Basin, which is one of the richest mining areas in the world. Its magnetic anomalies are very similar to the Sudbury Basin and so it could be a second metal-rich impact crater.

Famous quotes containing the words discovery and, discovery and/or structure:
“The new supplants the old. Yet men’s minds are stuffed with outworn bunk. Educating the young in the latest findings of authorities and scholars in the social sciences is important. It is equally important to devise ways and means for aiding the middle-aged and old to reexamine hang-over unscientific doctrines and ideas in the light of recent discovery and research.”
—Mary Barnett Gilson (1877–?)
“I have known no experience more distressing than the discovery that Negroes didn’t love me. Unutterable loneliness claimed me. I felt without roots, like a man without a country ...”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 1, ch. 10 (1962)
“One theme links together these new proposals for family policy—the idea that the family is exceedingly durable. Changes in structure and function and individual roles are not to be confused with the collapse of the family. Families remain more important in the lives of children than other institutions. Family ties are stronger and more vital than many of us imagine in the perennial atmosphere of crisis surrounding the subject.”
—Joseph Featherstone (20th century)
