Detrital zircon provenance studies of Terra Nova oil field strata, offshore Newfoundland, were conducted to constrain the depositional age and correlation of synrift sandstone units in the Jeanne d’Arc basin and test continuity with coeval rocks in adjacent regions. Braided fluvial sandstone intervals of the Jeanne d’Arc Formation from delineation wells K-18, C-09, and E-79 yield Mesozoic to Archean detrital zircon U-Pb populations that are consistent across the Terra Nova field. A Tithonian to Berriasian maximum depositional age for the Jeanne d’Arc Formation is proposed from circa 145 Ma detrital zircon grains in each of the nine sandstone samples analyzed. Tithonian to Berriasian detrital zircon grains have chondritic to superchrondritic Hf isotope compositions and indicate that synrift drainage systems carved valleys into the existing landscape during mantle-derived volcanism. Polycyclic Paleozoic to Archean detrital zircon grains were derived from mature, upper Paleozoic sedimentary rocks of the Avalon uplift south-southwest of the Jeanne d’Arc basin and have original provenance from the Newfoundland Appalachians, Canadian shield, and Iberia. Coeval synrift fluvial strata from the frontier Flemish Pass basin yield analogous Tithonian to Berriasian and Paleozoic to Archean detrital zircon populations and suggest potential Late Jurassic to Early Cretaceous continuity with Jeanne d’Arc basin units. Tithonian to Berriasian deltaic strata of the Scotian basin, southwest of the southwest Grand Banks fault zone, lack Mesozoic detrital zircon grains typical of Grand Banks basins and demonstrate that regional faulting and igneous activity controlled Late Jurassic to Early Cretaceous drainage patterns along the nascent Atlantic Canadian margin.

纽芬兰近海 Jeanne d'Arc 盆地 Terra Nova 油田上侏罗纪至下白垩统同裂谷地层的来源：加拿大大西洋边缘的新碎屑锆石 U-Pb-Hf 参考系

对纽芬兰近海 Terra Nova 油田地层进行碎屑锆石物源研究，以限制 Jeanne d'Arc 盆地同裂谷砂岩单元的沉积年龄和相关性，并测试与邻近地区同时期岩石的连续性。来自描绘井 K-18、C-09 和 E-79 的 Jeanne d'Arc 组的辫状河流砂岩层段产生中生界至太古代碎屑锆石 U-Pb 群，这些群在整个 Terra Nova 油田中是一致的。从所分析的 9 个砂岩样品中的每一个中的大约 145 Ma 碎屑锆石颗粒中，提出了 Jeanne d'Arc 地层的 Tithonian 至 Berriaasian 最大沉积年龄。Tithonian 到 Berriaasian 碎屑锆石颗粒具有球粒状到超时粒状 Hf 同位素组成，表明在地幔衍生的火山作用期间，同裂谷排水系统在现有景观中雕刻了山谷。多环古生界至太古代碎屑锆石颗粒来源于贞德盆地西南偏南阿瓦隆隆起的成熟上古生界沉积岩，原始来源为纽芬兰阿巴拉契亚山脉、加拿大地盾和伊比利亚。来自 Flemish Pass 盆地边界的同期同裂谷河流地层产生类似于 Tithonian 到 Berriasian 和古生代到太古代碎屑锆石群，并表明潜在的晚侏罗世到早白垩世与 Jeanne d'Arc 盆地单元的连续性。斯科舍盆地的提通阶至贝里亚斯三角洲地层，
