COLLABORATIVE RESEARCH: The Circum-Atlantic Large Igneous Province: Constraints from Mafic Rocks in the Southeastern U.S.A

[805433]哈梅斯：沿环大西洋的晚元古代至中生代中期的火山产生了地球上最广泛的大型基性火山活动之一。最近的研究表明，这种岩浆活动的形成时间只有几百万年。这个合作项目将集中在基性火山省尚未完全研究的部分，并将尝试测试时间限制，并将结果应用于各种模型，以确定泛古陆裂谷事件的驱动力

9805433 Hames The volcanoes of Late Proterozoic to middle mesozoic age along the circum-Atlantic produced one of the earth's most a really extensive large mafic volcanic occurrences. Recent work has indicated that much of this mafic magmatism was emplaced over only a few million years. This collaborative project will focus on an incompletely studied portion of the mafic volcanic province, and will attempt to test the timing constraints and to apply the results to various models for the driving forces for the Pangean rifting event
