9627909 Davis The Yinshan fold and thrust belt of northern China lies within the Mesozoic North China plate and is not clearly related to any of the three convergent margins of that plate that were active in Mesozoic time. This research is aimed at understanding the causes of this belt forming so far away from these margins, and whether the voluminous magmatism can be related to such distant subduction processes. Results may help understand other enigmatic orogenic belts that occur within plates but lie at considerable distances from the plate margin.

小行星9627909 中国北方阴山褶皱冲断带位于中生代华北板块内，与中生代活动的三个板块会聚边缘均无明显关系。 这项研究的目的是了解这条带形成的原因，如此遥远的边缘，以及大量的岩浆活动是否可以与这样遥远的俯冲过程。 这些结果可能有助于了解其他发生在板块内部但距离板块边缘相当远的神秘造山带。
