CPCP-1: Thermal demagnetization data

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 progressive thermal demagnetization data collected from the specimens from cores CPCP-1A and CPCP-2B.

Methods
The progressive thermal demagnetization data was generated by heating specimens in ASC TD-48 furnaces stored in a magnetically shielded room with a peak magnetic field of less than 10 nT. At each demagnetization step, the NRM and remanence were measured using either a 2G-Enterprises cryogenic magnetometer equipped with DC-squids or AGICO JR6A spinner magnetometers housed in a magnetically shielded room. AGICO data reduction software "Remasoft 3.0" was used to process the data and to calculate the characteristic remanent magnetization (ChRM) directions.
