Silicification in Mississippian Lodgepole Formation, Northeastern Flank of Williston Basin, Manitoba, Canada
Bibliographic record
Abstract
代替硅石的五种类型在 Williston 盆的东北胁腹上在更低的密西西比河的 Virden 成员碳酸盐被认出：微晶质的石英，石髓的石英， anhedral megaquartz， euhedral megaquartz，和象线的 megaquartz。硅石趋于代替各种各样的 bioclasts，并且都除了象线的 megaquartz，也作为 non-replacive 发生空充满的水泥或作为形成燧石小瘤和硅化的石灰石的硅石。尽管海百合纲动物，腕足类动物的一种，珊瑚， bryozoans，软体动物，三叶虫， forams，和 ostracodes 是在场的在里面，沉积学习了， silicification 的开始的三条仅仅表演证据。而腕足类动物的一种典型地由长度的小球体减缓玉髓，海百合纲动物被微晶质的石英通常代替。联合小球体，经常在同心戒指(beekite 戒指) ，可以在珊瑚和腕足类动物的一种的表面上形成像表的群众。尽管 bryozoans 在 Virden 成员是普通的，任何一个都没显示出 silicification 的任何证据。在到 silicification 的危险性的差别可能与壳微观结构，生物的组，有机体的尺寸，骨胳的矿物学，和 bioclasts 的器官的内容有关。从硅质的海绵骨针的溶解导出的源於生物的硅石被认为是为 silicification 的最可能的硅石来源。在沉积深深地被埋葬以前，最，硅石被相信在早成岩作用期间被释放。Virden 成员碳酸盐可能经历了代替的二个事件，首先影响 bioclasts，第二生产硅化的石灰石和燧石小瘤。

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.
