Evolution education poses unique challenges because students can have preconceptions that bias their learning. Hands-on, inquiry approaches can help overcome preset beliefs held by students, but few such programs exist and teachers typically lack acc

Dating magnetizations in Precambrian rocks is increasingly important in the attempt to unravel Precambrian plate configurations and supercontinent assemblages. We used low-temperature demagnetization and modern thermochronometric methods to dissect a

The Fountain Formation near Eldorado Springs, CO, USA, shows evidence of alteration by hydrothermal fluids that precipitated authigenic potassium feldspar (adularia) as rims on detrital feldspars and as interstitial cement deposits. Detailed 40Ar/39A

The great depth and relatively steep geothermal gradient (∼29°C/km) of the KTB deep crustal borehole, located in the Bavarian region of Germany, provides the basis for our study of diffusive argon loss in K-feldspar. The observed borehole temperat

Three studies have been conducted to test the usefulness of apatite U Th/He thermochronometry. The first study compared U Th/He and fission track ages from quickly cooled plutonic rocks having concordant zircon and apatite fission track ages. Several

A paleomagnetic study of 14 sites in the baked sedimentary rocks of the Newark basin Passaic Formation in southeastern Pennsylvania reveals two types of magnetic behavior. Dark gray-colored, baked sedimentary rocks have peak unblocking temperatures o

Results are presented of a paleomagnetic analysis of the Crescent Formation basalts of the northern Olympic Mountains, carried out with the purpose of constraining the emplacement and deformation history of the rocks of the northern Coast Range. It w

The remarkable early to middle Eocene volcanic sequence of the Crescent Formation exposed on the Olympic Peninsula consists predominantly of tholeiitic to minor transitional alkaline basalts with sparse sedimentary interbeds. A composite section meas
