Magnetic survey methods are ideal for locating burned areas, hearths, kilns, and fired bricks due to thermoremanent
magnetism (Kvamme, 2001).
An additional potential problem is the inclination shallowing that has been observed to affect the thermoremanent
magnetization (TRM) in lava flows from other places (Lanza et al.
This process is known as thermoremanent
magnetization, and it is characterized because of its stability in the time.
Geophysicists have long used this leftover magnetization, called thermoremanent
magnetization (TRM), as a tool to trace changes in the earth's magnetic field and as a yardstick to measure the drift of the continents.
