1 WIRGO in TIC's? [What (on Earth) is Really Going On in Terrestrial Impact Craters?] or Structural Evidence from Shock Metamorphism
Bibliographic record
Abstract
Canada is well endowed with impact craters formed in crystalline rocks with relatively homogeneous physical properties. Representative craters are listed below. They exhibit all the main morphological-structural variations with crater size seen in craters on other rocky planets, from small simple bowl to large peak and ring forms. They demonstrate that form is not dependent on variations in the physical properties of the target material, though such variations may be important modifiers. Lacking stratigraphy, analysis is based largely on the imprint of shock melting and metamorphism, to give insights into the mechanics of crater formation. Attention is directed to the limit of initial brecciation due to shock wave reverberations and its position of relative to level of shock metamorphism, and the distribution of shocked target that lies in the para-autochthone outside the limit of breccia development. In addition the form and distribution of late stage shears and breccias formed by late stage movements is important. Simple craters, exemplified by Brent (D=3.8km) allow direct comparison with models and experimental data. Results of interest include:
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.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
