Taoyuan gold deposit locates in impurity carbonate rock containing volcanic materials of Lower Carboniferous, lower rock formation, littoral-neritic facies.
桃园金矿床赋存于下石炭统下岩组滨浅海相含火山喷发物的不纯碳酸盐岩中，金矿化严格受断裂构造控制。
During this period, the basin can be divided to three parts, including northern depression, southern depression and central rise belt. The southern depression is continental margin nearshore open basin with littoral-shelf clastic deposit.
该时期盆地以中央隆起带为界，南部为陆缘开阔海盆地，形成滨岸浅海陆棚相碎屑岩沉积；
The foundation at Tianjin coastal region is a typical littoral facies & the deposit soft soil of land cross the sea, but the spectrum of seismic wave is a major consideration of structure seismic design.
天津滨海新区地基土属于典型的滨海相&海陆交互相沉积的软土，而地震波的频谱特性是建筑工程结构抗震设计中的主要考虑因素。
