Klethla Valley sherds

Thirty-two sherds representing five different examples of Kayenta Anasazi Pueblo II pottery (Tusayan Corrugated [TC], Medicine Black-on-Red [MB], Tusayan Black-on-Red [TB], Dogoszhi Black-on-White [DB], and Sosi Black-on-White [SB]) have been analyzed for the elements As, Ba, Co, Cr, Cm, Fe, Mn, Ni, Pb, Se, V, and Zn by using the techniques of flame atomic absorption spectroscopy (.FAA) and electrothermal atomic absorption spectroscopy (ETAA). Analytical procedures for the chemical analysis of ceramics afford accuracy and sensitivity and require only a modest capital investment for instrumentation. The sherd samples were collected at two sites, one in southern Utah (Navajo Mountain [NM]) and the second in northern Arizona (Klethla Valley [KV]). These sites are approximately 60 km apart. Statistical treatment of the data shows that only three clay types were used in the 32 sherds analyzed, and that only three elements (Fe, Pb, and Ni) are necessary to account for 100% of the dispersion observed within this sample set. 

Experimental Design. To simplify the interpretation of results, sherd samples were selected for analysis from the Pueblo II era (ca. 900-1150 A.D.). Samples from only two sites that were known to have been occupied by the Kayenta Anasazi were examined (40). Figure 1 shows the area of the Kayenta Anasazi and identifies the two sites (Navajo Mountain and Klethla Valley) where sherds were collected. 

The results of the chemical analysis of the sherds are listed in Table II (Klethla Valley samples) and Table III (Navajo Mountain samples). Each number shown in Tables II and III is the average value of at least three separate...
