Abstract

fetched live from OpenAlex

Introduction: A study of well, 2D and 3D seismic data was conducted in order to better understand impact processes and the deformational history the Eagle Butte impact structure. The impact feature was first identified by Sawatzky [1]; Lerbekmo et. al. [2] suggested a 200m impactor formed this structure. Located within the Western Canada Sedimentary Basin, in southern Alberta, this 15 km complex structure displays a prominent central uplift, annular synform, and rim uplift within Cretaceous and Lower Tertiary strata. Formed primarily in shaly sediments mineralogical evidence of shock metamorphism has not been found, but shattercones occur at one subcrop locality near the center of the central uplift (Figure 1).

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
