Magnetostratigraphy and Tectonic Rotation of the Eocene-Oligocene Makah and Hoko River Formations, Northwest Washington, USA

Figure 6

Magnetic stratigraphy of the type section of the Makah Formation at Baada Point. Solid circles are Class I sites of Opdyke et al. [55], which have three or more sample directions that are statistically removed from a random distribution at the 95% confidence level. Hachured circles are Class II sites of Opdyke et al. [55], which had only 2 samples that survived sampling and transport, so no statistics could be calculated. Open circles are Class III sites of Opdyke et al. [55], where two directions show a clear polarity preference, but the third sample direction is divergent. Stratigraphy modified from Snavely et al. [8, Figure 4].
