- It is substantially strata-bound by the lower Sinian Lantian Formation under the outer contact zone of the Yanshanian fine-grained g. 该矿床主要受燕山期细粒花岗岩外接触带下震旦统蓝田组层位控制,从蓝田组一段至蓝田组四段均有矿体分布。
- The great majority of gold deposits in North China platform are hosted by the Archeozoic strata or emplaced in the Yanshanian magmatic intrusives of the Archeozoic strata. 华北地台中绝大多数金矿赋存于太古宙地层或侵入于太古宙地层中之燕山期岩浆岩体内。
- The occurrence of the Yanshanian granites indicates that the main sinistral strike-slip movement of the Tan-Lu fault system probably took place during the late Indosinian epoch. 它控制燕山期花岗岩产出空间，指示郯庐断裂带左行平移可能发生在印支晚期。深断裂的属性使其成为金矿重要的区域控矿构造。
- The structural system began to develop during the Indo-sinian orogeny,took full shape in the Yanshanian movement,and had a strong activity in the Himalayan epoch. 华南山字型是印支期发生发展，燕山期成型和定型，喜马拉雅期仍有较强活动的构造体系。
- The wind whirled the dead leaves about. 风吹得枯叶在四处回旋。
- In China, the Yanshanian is the most important period of metallizing process of gold, followed by the Variscan, Luliang-Jinningian, Wutainian and the Himalayan periods. 而我国金矿床的成矿时代则以燕山期为最重要，吕梁－晋宁期和海西期次之，其馀为五台期和喜马拉雅期。
- The wind was whispering in the trees. 一阵风穿过树林沙沙作响。
