浙江涅渚铁矿床产于上震旦统西峰寺组碳酸盐岩层中。矿床以条带状磁铁矿矿石为主,也产有矽卡岩和浸染矿石及块状矿石。许多研究者认为此矿床是砂卡岩型。今研究表明,矿床的东矿带为岩浆热液一强烈改造型层控矿床,西矿带为岩浆热液一轻微改造型层控矿床。 The Niehwa iron ore deposit of Zhejiang Province was produced in the carbonate strata of the Upper Sinian Xifengsi Formation. The deposit is dominated by banded magnetite ore and is also produced with skarn and disseminated ore and massive ore. Many researchers think this deposit is of the type of sandstone. This study shows that the eastern ore belt is a strongly remodeled strata-hosted ore deposit of magmatic hydrothermal fluid and the west ore belt is a slightly altered stratigraphic controlled ore deposit of magmatic hydrothermal fluid.
