Figure F146. Measurements of (A) magnetic susceptibility and (B) remanent intensity before and after 30-mT AF demagnetization for Sections 210-1276A-33R-2 through 38R-3. Muddy sandstones from Sections 210-1276A-36R-1 through 36R-6 show high magnetization peaks. NRM = natural remanent magnetization.
