description Richard Doell Overview
Richard Doell (1923–2009) was an American paleomagnetist who worked for the United States Geological Survey. Alongside colleagues Allan Cox and Brent Dalrymple, he constructed the first geomagnetic polarity reversal timescale in the early 1960s by dating magnetized volcanic rocks. This foundational research played a crucial role in verifying the seafloor spreading hypothesis and establishing plate tectonics as the prevailing geological framework.

help Richard Doell FAQ
What is Richard Doell famous for in the field of geology?
Richard Doell was an American paleomagnetist who is most famous for co-constructing the first geomagnetic polarity reversal timescale in the early 1960s. He completed this foundational work alongside his colleagues Allan Cox and Brent Dalrymple.
Did Richard Doell work for the United States Geological Survey?
Yes, Richard Doell worked as a paleomagnetist for the United States Geological Survey (USGS). During his time there, he helped analyze magnetized volcanic rocks to map out Earth's historical magnetic field reversals.
Who did Richard Doell work with to create the geomagnetic polarity reversal timescale?
Richard Doell collaborated closely with fellow scientists Allan Cox and Brent Dalrymple. Together, they dated volcanic rocks to establish the first reliable timeline of Earth's magnetic pole reversals, which provided crucial evidence for plate tectonics.
How did Richard Doell determine the age of Earth's magnetic field reversals?
Doell and his team determined these dates by examining and dating magnetized volcanic rocks. By measuring the magnetic orientation and the potassium-argon decay in these rocks, they constructed the first geomagnetic polarity reversal timescale in the early 1960s.
