The Colorado Plateau Coring Project Phase 1 (CPCP-1) acquired three continuous drill cores from Petrified Forest National Park (PFNP), Arizona, U.S.A. Two cores, CPCP-PFNP13-1A and CPCP-PFNP13-2B, hereafter CPCP-1A and CPCP-2B; respectively, intersected the Upper Triassic Chinle Formation, Lower(?)-Middle Triassic Moenkopi Formation (MF) and Permian Coconino Sandstone. We examined CPCP-1A and CPCP-2B cores to construct a high-resolution magnetostratigraphy of Moenkopi Formation strata. These data files contain anisotropy of magnetic susceptibility (AMS) data collected from the specimens from core CPCP-2B.

Anisotropy of magnetic susceptibility (AMS) data was obtained on all specimens of appropriate size/shape from the core CPCP-2B using an AGICO MFKI-A system equipped with an automatic 3D rotator.

AMS data can be opened in AGICO free AMS data viewing and processing software "Anisoft5". To view the data in geographic coordinate use an azimuth/hade of 113°/90° (CPCP-2B) and the following orientation parameters in Remasoft 3.0 (P1= 12; P2= 0; P3= 12; P4= 0 or 90).
