The analysis here of chert and quartzite source samples from the Hartville Uplift, Wyoming indicates relatively low variability in the chert samples, and somewhat higher variability in the quartzite samples, particularly in the major and minor oxides and some of the trace elements such as strontium and barium. Also, a previously unpublished analysis by this lab of Spanish Diggings, Wyoming chert for Bruce Huckell at the University of New Mexico is compared to the Hartville chert using the oxides of potassium and calcium, and trace elements Zn and Zr (see also Shackley 1999). This study is mainly seen as an exploratory exercise compositionally documenting the Hartville Uplift chert and quartzite. The comparison with the Spanish Diggings samples is for illustrative purposes.
