1935年朱森等研究宁镇山脉地质时,首先提出中三叠世末期这里发生过重要的地壳运动,称金子运动,上三叠统黄马青群底部有石灰岩质角砾岩不整合在下中三叠统青龙群之上。1945年喻德渊研究了安庆地区的同一地壳运动,黄马青群底部角砾岩同样不整合在青龙群之上,称淮阳运动,并强调淮阳运动结束了古生代以来下扬子地区长期海侵的历史,在地质发展中具有重要的变革作用。李四光从区域的角度肯定了金子运动(淮阳运动)在华南和东南亚地区的地质意义。1962年以来,不少单位和个人对此期运动作了研究,并肯定了它的存在。
When Zhu Sen et al. Studied the geology of the Ningzhen Mountains in 1935, he first proposed that there had been an important crustal movement here at the end of the Middle Triassic period, saying that the gold movement was accompanied by the unconformity of the limestone breccia at the bottom of the Huangmaqing Group in the Upper Triassic to the lower middle Triassic Above the dragon group. In 1945, Yu Deyuan studied the same crustal movement in the Anqing area. The bottom breccia in the Huangmaqing group also did not integrate above the Qinglong group, calling it the Huaiyang movement and emphasized that the Huaiyang movement ended the history of long-term transgression in the Lower Yangtze region since Paleozoic. In the geological development has an important role in the transformation. Li Siguang affirmed the geological significance of the gold movement (Huaiyang Movement) in South China and Southeast Asia from a regional perspective. Since 1962, quite a few units and individuals have studied this period movement and affirmed its existence.
