Abstract
The East Coast of Canada presents multiple passive continental margin basins (PCMBs) characterized by significant architectural differences and limited oil and gas discoveries, establishing these basins as the global frontier for hydrocarbon exploration. Limited understanding of the characteristics of basin architectures and their control of hydrocarbon accumulation hinders exploration breakthroughs in these basins. Using magnetic anomaly, seismic, and drilling data, this study conducts integrated geological and geophysical interpretations of the PCMBs. Accordingly, this study reveals that the PCMBs have undergone three evolutionary stages, namely rifting (comprising three episodes), depression, and continental margin, with the synthem of each stage being referred to as rift layer, depression layer, and continental margin layer, respectively. Under the control of transform faults and basement nature, four distinct types of PCMBs have formed: transtensional, transform, gentle-rampy, and volcanic rifted types from south to north. The basins with varying architectures govern the sedimentary filling, the combination of petroleum system elements, and differential hydrocarbon accumulation across three major types of synthems. Furthermore, this study highlights substantial hydrocarbon exploration potentials in the turbidite sandstones within the slope and basin-floor areas of the transtensional and transform types of PCMBs, as well as in the deltaic sandstones within the rift and depression layers of the gentle-rampy type of PCMBs.

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 it
