Abstract

fetched live from OpenAlex

Forty six species of fossil spores and pollen assigned to thirty nine genera are recorded from 6 samples of Borehole HC2 in the Hami Depression, Xinjiang, Northwest China. Two sporopollen assemblages, Limatulasporites Cyclogranisporites Alisporites (of the Jiucaiyuan Fm.) and Limatulasporites Lundbladispora Taeniaesporites Assemblages (of the Shaofanggou Fm.), have been proposed. The present assemblages are comparable with those from the Jiucaiyuan and Shaofanggou Formations located on the south margin of the Junggar Basin and the Early Triassic assemblages from Australia and Western Canada, suggested an Early Triassic age for the Jiucaiyuan and Shaofanggou Formations in the Hami Depression. The discovery of the sporopollen assemblages from Borehole HC2 provides paleontologic evidence for the existence of the Lower Triassic strata in the Hami Depression, Xinjiang.

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 distilled prediction

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.
