Abstract

In the Emarat Pb-Zn deposit located in the Markazi province, underground exploration and exploitation activities have been carried out at the various elevation levels through drilling tunnels and cross-cuts. In the present research, 2D and 3D modeling of surveyed faults at the variety of levels were performed studying their relationship with ore-bearing in the region qualitatively and quantitatively. To achieve the goal, a complete statistical study was done, first. Afterward, 2D strike and dip map with rose diagram, 2D grid-based map, 3D strike and dip diagram and solid model of the faults surveyed at the various elevation levels were drawn and analyzed using methods and different mathematical algorithms applied in geosciences. In addition, a stratified iso-grade map of total Pb-Zn for different elevation levels was also produced. The qualitative comparison of 2D grid-based maps and iso-grade maps for each elevation level peer to peer shows that in general, trend of mineral depositing follows the trend of faults frequency but frequency of the faults number in each zone does not much affect on the deposit grade. Also, the linear correlation coefficient between the faults number and deposit grade at the various elevation levels was obtained 0.157 on average, equaling to "very low" correlation. In fact, the results of the quantitative correlation at the different elevation levels, confirm the results of the qualitative correlation study.
