| 摘 要： | 通化地区珍珠门组并非老岭群的顶部层位，其上确实存在花山(大栗子)组、临江组．并且与珍珠门组呈平行不整合接触。这一发现，为重新厘定集安岩群、老岭群的地层层序以及区域地层对比．提供了直接的地质依据，也为老岭群的古地理再造以及地质构造演化研究提供了新资料；同时也为在这一地区寻找古岩溶型矿产提供了重要线索。

| Abstract: | The Zhenzhumen Formation in the Tonghua area, is not the top strata of the Laoling Group and is overlain by the Huashan (Dalizi) Formation, Linjiang Formation, showing parallel an unconformity contact with the Zhenzhumen Formation. This discovery provides a geologic basis for redefiniting Ji'an terrane, stratigraphic sequence of Laoling Group, and regional strigraphic correlation, also, it provides the new information of psleogeographic reconstruction of the Laoling Group and evolutionary process of geological structures, meanwhile, gives an important clue to discover palaeokarst type mineral resources in the study area. |
