9805461 Ruppel 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 that produced the present day Atlantic Ocean.

小行星9805461 沿着环大西洋的晚元古代到中生代中期的火山形成了地球上最大的一个真正广泛的大型镁铁质火山。 最近的研究表明，这种镁铁质岩浆活动的大部分只发生了几百万年。 这一合作项目将侧重于对镁铁质火山区未完全研究的部分，并将尝试测试时间限制，并将结果应用于各种模型，以确定产生今天大西洋的盘古大陆裂谷事件的驱动力。
