Abstract

Abstract

The Lengshuikeng silver-lead-zinc ore field in Jiangxi Province is located on the southern side of the suture zone of the Yangtze block and the Cathaysian block, and the intersection of the Wuyi silver polymetallic metallogenic belt and the Qinhang metallogenic belt. It is an important silver-lead-zinc ore field in China. Based on the geological data of ore field geological map, exploration line profile and borehole histogram, using GOCAD software, the three-dimensional model of porphyry body, fracture and ore body, as well as the grade model of ore body have been established, which provides a visual representation of the relationship between ore-forming geological bodies. This model further confirmed that the porphyry ore body is produced in the front and main zones of the granite porphyry, and is controlled by the regional nappe structure. The silver grade distribution is spatially variable, with high-grade ores mainly distributed in the upper part of the ore body, and the grade distribution of lead and zinc is relatively uniform; the ore body is mostly produced between F1 and F2, and both the ore body and the granite porphyry body are controlled by fractures. The establishment of the 3D model of the Lengshuikeng silver-lead-zinc ore field provides important technical support for future prospecting of the deep edge of the ore field, especially for the exploration of the peripheral and deep concealed porphyry ore bodies.
