1 Methods: Sample Preparation, Irradiation, and Quantitative Analysis The ceramics were prepared for INAA by using a silicon carbide burr to remove painted or slipped surfaces and adhering soil; the fragments were then washed with deionized water and allowed to air dry before being crushed in an agate mortar to yield a fine powder. The powder samples were oven-dried at 100 degrees C for 24 hours. Approximately 150 mg portions were placed in small polyvials used for short irradiations, while 200 mg of each sample were weighed into high-purity quartz vials used for long irradiations. Along with the unknown samples, reference standards of SRM-1633a (coal fly ash) and SRM-688 (basalt rock) were similarly prepared, as were quality control samples (i.e., standards treated as unknowns) of SRM-278 (obsidian rock) and Ohio Red Clay. INAA of ceramics at MURR consists of two irradiations and a total of three gamma counts (S1, S2). A short irradiation is carried out through the pneumatic tube irradiation system, with samples sequentially irradiated for five seconds at a neutron flux of 8 x n/cm 2 /s. The 720-second count yields gamma spectra containing peaks for the short-lived elements aluminum (Al), barium (Ba), calcium (Ca), dysprosium (Dy), potassium (K), manganese (Mn), sodium (Na), titanium (Ti), and vanadium (V). The samples encapsulated in quartz vials are subjected to a 24-hour irradiation at a neutron flux of 5 x n/cm 2 /s. After the long irradiation, samples decay for seven days and are counted for 2,000 seconds (the middle count ) on a high-resolution germanium detector coupled to an automatic sample changer. The middle count determines seven medium halflife elements, namely: arsenic (As), lanthanum (La), lutetium (Lu), neodymium (Nd), samarium (Sm), uranium (U), and

2 ytterbium (Yb). After an additional three- or four-week decay, a final count of 9,000 seconds is carried out on each sample, yielding the following 17 long halflife elements: cerium (Ce), cobalt (Co), chromium (Cr), cesium (Cs), europium (Eu), iron (Fe), hafnium (Hf), nickel (Ni), rubidium (Rb), antimony (Sb), scandium (Sc), strontium (Sr), tantalum (Ta), terbium (Tb), thorium (Th), zinc (Zn), and zirconium (Zr). All of the resulting elemental concentration data from the three counts (usually a total of 33 elements, although some elements, especially nickel, were below detection levels) are assembled into a single tabulation. Quantitative analysis is subsequently carried out on base 10 logarithms of concentrations for these data. Use of log concentrations instead of raw data compensates for differences in magnitude between major elements, such as iron, on one hand and trace elements, such as the rare earth or lanthanide elements, on the other hand. Transformation to base 10 logarithms also yields a more nearly normal distribution for many trace elements. The goal of quantitative analysis of the chemical data is to recognize compositionally homogeneous groups, assumed to represent geographically restricted sources or source zones. The location of sources or source zones may be inferred by comparing the unknown groups to knowns (source raw materials) or by indirect means; both indirect and direct means are used in the present study. Whether a group is discriminated easily from other groups can be evaluated visually in two dimensions or statistically in multiple dimensions. A metric known as Mahalanobis distance (or generalized distance) makes it possible to describe the separation between groups or between individual points and groups on multiple dimensions. Because Mahalanobis

3 distance takes into account variances and covariances in the multivariate group it is analogous to expressing distance from a univariate mean in standard deviation units. Like standard deviation units, Mahalanobis distances can be converted into probabilities of group membership for each individual specimen. With small groups, Mahalanobis distance-based probabilities of group membership may fluctuate dramatically depending on whether or not each specimen is assumed to be a member of the group to which it is being compared. This problem can be circumvented by cross-validation (or jackknifing ), that is, by removing each specimen from its presumed group before calculating its own probability of membership (S1-S3). This is a conservative approach to group evaluation that may sometimes exclude true group members but minimizes the chances of erroneous attribution. Such a conservative approach is preferable because it minimizes chances that Olmec-style sherds found outside the Gulf Coast will be erroneously identified as imports rather than local production. Since cross-validated probabilities are used, the results presented below represent a conservative picture of the volume of ceramics that were moved between regions during the San Lorenzo horizon.
