马元位于陕西省西南边陲,四川盆地东北缘,汉中盆地西南部。四川盆地矿产资源丰富,它是我国石油工业最早展开勘探的地区,是我国第一个天然气工业基地,金属矿产资源在该盆地中及盆地边缘均有产出。其中,盆地边缘发现一大批具有工业价值的大型、中型、小型铅锌矿床,如:四川盆地与滇黔交界处的会理天宝山、会东大梁子、甘洛赤普大型铅锌矿床等;四川盆地东北缘与陕西交界处的马元铅锌矿。马元铅锌矿赋存于震旦系灯影组白云岩中,角砾状白云岩为铅锌矿的富矿层段,属于典型的密西西比河谷型
Ma Yuan is located in the southwestern margin of Shaanxi Province, the northeastern margin of Sichuan Basin, southwestern Hanzhong Basin. Sichuan Basin is rich in mineral resources. It is the earliest exploration area in China’s oil industry. It is the first natural gas industrial base in China. Metals and mineral resources are produced both in the basin and on the margin of the basin. Among them, a large number of large-scale, medium-sized and small-scale lead-zinc deposits with industrial value have been found on the edge of the basin, such as the Tianli Mountain in Huili, the Huidongtianlizi in Huidong, the large Pb-Zn deposit in Ganluo Shipu at the junction of Sichuan Basin and Yunnan- Ma yuan lead - zinc mine at the junction of the northeast margin of Sichuan Basin and Shaanxi Province. The Pb-Zn deposit in Ma Yuan is hosted in the Sinian Dengying Formation dolomite. The brecciated dolomite is a lead-zinc ore-rich ore layer and belongs to the typical Mississippi Valley type
