| 摘 要： | 作者在建德铜矿石炭纪地层中发现了与地层整合产出的层状硅质岩。硅质岩常量元素，向量元素，稀土元素和包裹体地球化学特征表现为热水沉积硅质岩。由于热水沉积硅质岩与层状矿体密切共生，故本区水沉积硅质岩的发现对解决建德铜矿成因和在本区寻找同类矿床具有重要意义。

| Abstract: | The bedded cherts which are in conformity with the Carboniferous System stratum are discovered in Jiande Copper Deposit,Zhejiang Province.Cherts can be identified as hydrothermal sediment ones by the gochemical characteristics of theirs major elements,trace elements,rare earth elements and quartz inclusions.As the hydrothermal sediment cherts are intergrowth closely with bedded orebody,the discovery of these cherts has an important significance on both determining the origin about Jiande Copper Deposit and prospecting the same ore deposits in this area. |
