摘要
皖南桃冲铁矿属于长江中下游富铁富铜成矿带之一例。多年来,该矿床一直被误认为远离侵入体矽卡岩型高温热液镜铁矿矿床。通过对该矿床及其所属长龙山、寨山两个箱形倒转背斜两翼所赋存的铁矿的研究,从矿床所处构造位置、矿床特征等方面分析、论证,提出桃冲铁矿床成因为同生沉积-热力变质再造型穆磁铁矿矿床。
Taochong iron ore-deposit in south-Anhui province belongs to one of the deposits of the middle andlower Yangtze rive ore-deposit belt, which is rich in iron and copper.But it was mistaken as hydrothermalspecularite Ore-deposit of skarn type formed by high-teperture and was far from intrusion. By the studies ofthis deposit and other iron-ore deposits dept within the two wings of two inverted box anticlines, Changshaniverse anticline and Zhaishan inverse anticline, within which Taochong iron-ore deposit was found, and basedon the analyzing of tectonic posion of bearing deposit and the characteristics of the ore beds, the article haspointed out that the Taochong iron-ore deposit is mush-magnetite-ore deposit formed by syngenetic sediment-contact thermal metamopphism modified.
