Until the mid 1960s, magnetic polarity time scales were calibrated using only continental volcanic rocks younger than 5 million years old.
The first long (pre-Pliocene) magnetic polarity time scale was proposed by geophysicists from the Lamont-Doherty Geological Observatory of Columbia University in 1968.
During the 1970s, magnetostratigraphic studies from pelagic limestone sections of land and deep sea sediments drilled during DSDP confirmed most of the magnetic polarity intervals (or chrons) determined from profiles of marine magnetic anomalies.
No less than 10 short magnetic polarity features lasting less than 30,000 years (microchrons) have been proposed for the last 3 million years.
One of the current major objectives of research in magnetostratigraphy is to confirm the existence of the short magnetic polarity events.
The magnetic polarity of the spots alsovaries cyclically.
Geologists participating in the project will retrieve coresamples and use in-hole sensors to examine the physical and chemical nature of rock formations, measure the stress on the rock, trace the relationship between pore pressure and earthquakes, investigate shifts in the earth's magnetic polarity and determine the temperature of the rock and fluid found in the hole.
The cooling lava took on the prevailing magnetic polarity of the earth.
