Newly compiled U-Pb detrital zircon data from eight geographic domains along the eastern Laurentian margin from Newfoundland (Canada) to Alabama (United States) show a highly consistent signature along strike, with only minor local variations. The Precambrian signature is characterized by a small ca. 2.7 Ga population and a major ca. 1.9–0.9 Ga population that peaks at ca. 1.2–1.0 Ga. Detrital zircon populations are from Laurentian Archean crust (ca. 2.7 Ga population), Paleoproterozoic orogens (ca. 1.9–1.6 Ga), the Granite-Rhyolite Province (ca. 1.5–1.4 Ga), and the Elzevir terrane and Grenville Province (ca. 1.3–0.9 Ga). The Mesoproterozoic populations vary in size depending on proximity to the ca. 1.5–1.4 Ga Granite-Rhyolite Province, the ca. 1245–1225 Ma Elzevir terrane, and the ca. 1.2–0.9 Ga Grenville Province. A middle Ordovician zircon population varies in size along strike depending on input from the Taconic orogenic belt, but it is strongest in the northern Appalachians. Because of the general along-strike consistency in detrital zircon age populations, the compilation of all 7534 concordant U-Pb detrital zircon data can be used in future U-Pb detrital zircon studies as an indicator for eastern Laurentian margin sources.

阿巴拉契亚山脉东部劳伦山脉边缘的碎屑锆石种群

从纽芬兰（加拿大）到阿拉巴马州（美国）沿Laurentian东部边缘的八个地理区域，最新编制的U-Pb碎屑锆石数据显示出沿罢工的高度一致的特征，仅局部变化很小。前寒武纪的特征是一个小的ca。2.7 Ga人口和主要。1.9–0.9 Ga人口大约在 1.2–1.0 Ga。碎屑锆石种群来自Laurentian Archean地壳（约2.7 Ga），古元古代造山带（约1.9–1.6 Ga），花岗岩-流纹岩省（约1.5–1.4 Ga）和Elzevir地和格林维尔省（约1.3–0.9 Ga）。中元古生代种群的大小因与ca的接近而不同。1.5–1.4 Ga花岗岩-流纹岩省，1245年至1225年Ma Elzevir地形，以及 加格林维尔省1.2–0.9。奥陶纪中层锆石种群的数量随塔科尼克造山带的输入而变化，但在北部的阿巴拉契亚山脉最强。由于碎屑锆石年龄群体的总体走向一致，所有7534个一致的U-Pb碎屑锆石数据的汇总可用于未来的U-Pb碎屑锆石研究，作为东部Laurentian边缘源的指标。
