Abstract

fetched live from OpenAlex

ABSTRACT. The Torngat Archaeology Project is involved in a raw materials program that includes the “finger-printing ” of certain lithics used by prehistoric cultures in Labra-dor, and the identification of their geological sources. Field work was carried out in 1978 in the Ramah and Mugford areas to sample chert outcrops and search for evidence of prehistoric quarrying and manufacturing activities. Numerous quarries and workshops were discovered id the Ramah Group, and a suite of Ramah and Cod Island chert samples was collected for analyses. Thin sections of four visually similar rock types from Labrador- Ramah chert, Cod Island chert, Saglek quartzite, and Ryan’s quartz- were examined and samples of each were submitted for trace element analysis by neutron activation. Given the high purity of the cherts and the small number of samples used in the preliminary activation analysis, confident identification of and strong discrimination between the four, based on trace element concentrations, were not possible. However, thin section examination enabled identifications and differentiations to be made based on the petrographic features of each of the lithics.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
