Notes
Thin sections were prepared of the different lithologies from each core. Standard petrographic techniques were used to identify constituent minerals and to obtain modal analyses. The number of points counted varied from about 500 to several thousand, depending upon the grain size of the rock. Whole-rock chemical analysis was performed by John Husler, University of New Mexico, using a variety of techniques (Laughlin and Eddy, 1977). The precision for SiO2 is + 1% relative; for the other oxides it is + 2% relative. Accuracy was monitored by using USGS standard rock samples. Where necessary, the electron microprobe, scanning electron microscope, and X-ray diffractometer were used to identify mineral phases.
