Involvement of a Tertiary Foreland Basin in the Eurekan Foldbelt Deformation, NW Coast of Kane Basin, Ellesmere Island, Canada
Bibliographic record
Abstract
Summary: Along the NW eoast of Kane Basin (Ellesmere Island), a flatlying eonglomerate sueeession of a Tertiary foreland basin is overthrust by thiek Early Paleozoie sediments during the Tertial')' Eurekan deformation. In the sourhern study area between Franklin Pierce Bay and Dobbin Bay, Cambrian to Silurian sediments are thrust over the Tertiary basin along the Parrish Glaeier anel Cape Hawks thrusts. In front of the Parrish Glacier Thrust, Ordovician/Silurian, Cretaceous and Tertiary deposits are involved into a stack of several thrust sheets along dctachments characterized by flat-ramp gcometries, Due to erosion, sornc of the thrust sheets are cxposcd in klippcn and comprisc a tectonic inversion of the rock units. The N-dipping Allman Bay Reverse Fault on the peninsula between Franklin Pierce Bay anel Allman Bay rcprcscnts the southernmost exposed Eurekan strueture in the Dobbin Bay area. The transport directions are predominantly towards SSE and S. In the northern study area at Cape Lawrcnce, Cambrian and younger sedimcnts are thrust over the Tertiary basin along the WNW-dipping Rawlings Bay Thrust Zone. Between the Cambrian of the hanging wall and the Tertiary of the footwall, folded Ordovician evaporites and carbonates are imbricated in the thrust zone. The thick Tertiary eonglomerate beds below the Rawlings Bay Thrust Zone arc also affected by intense Eurekan shortening which is charaeterized by flat-lying detachments, folds and triangle structures. Hcre, the transport directions are to the E and ESE. In the study areas, the Eurekan deformation is characterized by compression with SSE- to E-directed tectonic transport towards the basement bloeks of the GreenIand-Canadian shield SE of Narcs Strait and S of Prineess Marie Bay. Only at Cape Lawrencc, a largc-scale, SE-vergent anticlinal synelinal pair and a NW-dipping reverse fault in the Tertiary eonglomerate eould be related to sinistral strike-slip movements along Nares Strait after deposition of the eonglomerate and prior to the Eurekan comprcssion along the Rawlings Bay Thrust Zone.

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.
