陕西铜厂铁矿床是陕南铁矿石重要产地之一,与国内外一些类似矿床相比,该矿床有很多独特之处。关于它的成因,众说纷纭,有的认为矿体靠近侵入体,属接触交代型铁矿床;有的认为铁矿受一定的地层层位控制,属沉积变质改造型矿床;也有人认为属与火山岩有关的矿床。为了弄清矿床的成因、物质来源,并扩大找矿远景。近年来,我们对该矿床作了同位素年龄和硫、氧稳定同位素地球化学的研究,现将所获资料整理成文,介绍如下。
Shaanxi Copper Plant iron ore is an important source of iron ore in southern Shaanxi, with some similar deposits at home and abroad compared to the deposit has many unique features. Some people think that the ore body is near the intrusive body and belongs to the contact metasomatism iron ore deposit. Some think that the iron ore is controlled by certain stratigraphic layers and belongs to the sedimentary metamorphic ore deposit. Some people think that the ore body belongs to the volcanic rock Related deposits. In order to clarify the origin of the deposit, the source of the material and the prospect of prospecting. In recent years, we have made isotope age and sulfur, oxygen stable isotope geochemistry of the deposit, the data obtained are now organized into text, introduced below.
