四川盆地是中国具有找矿前景的铅锌成矿区带之一,盆地中部及其周缘广泛出露震旦系碳酸盐岩地层,该层位发育有许多不同规模的铅锌矿床。马元铅锌矿床位于四川盆地东北缘,是近年来取得重大找矿突破的铅锌矿床。国内外学者对马元铅锌矿床进行过较为系统的研究,对矿床的地质特征、矿石特征、地球化学、成因模式、成矿年龄等方面进行了探讨。马元铅锌矿床大地构造位置处于扬子克拉通北缘的米仓山隆起带东缘—陕西汉中南部碑坝(杂岩)
The Sichuan Basin is one of the lead-zinc metallogenic belts with prospecting potential in China. Sinian carbonate strata are widely exposed in the central and peripheral areas of the basin. There are many lead-zinc deposits of different sizes in this layer. The Pb-Zn deposit in Ma Yuan is located in the northeastern margin of the Sichuan Basin and is a lead-zinc deposit that has made significant breakthrough in prospecting in recent years. Domestic and foreign scholars conducted a systematic study of the MaYuan Pb-Zn deposit and discussed the geological features, ore features, geochemistry, genesis model and metallogenic age of the deposit. The geotectonic location of the Ma-yuan lead-zinc deposit is located at the eastern margin of the Meikangshan uplift on the northern margin of the Yangtze craton.
