geometric modeling of pb-zn deposit in the south of markazi province

The pb-zn deposit is located in the south of markazi province. from the geo-structural point of view, it is in the median part of the sanandaj-sirjan zone and from the mineralization aspect it is part of the malayer-esfahan pb-zn metallogenic belt. geometric modeling plays an important role in the continuation of mining and extraction operations. based on the findings of the exploration stages, we will be able to carry out a successful mining operation. 3d geological modeling (3 dgm) helps geologists quantitatively in three-dimensional space structures study that defines temporal and spatial relationships between geological objects. the 3d model can also be used to discover the causes of geological objects. in this study, multiple different data of pb-zn deposit arak were combined in a three-dimensional environment. with the help of a geological map of the area, the surface geology model procedure was constructed using datamine software. the results show that, according to geological data, geophysics, geochemistry, boreholes and cross-sectional data, there is good mineralization of pb-zn deposit in the study area. effective study of 44 boreholes and 4 sections to create three-dimensional models was performed by kriging interpolation method. by comparing three-dimensional ore structures and metallogenic geological explorations, mineralization and potential goals of mineralization models in the study area, it was confirmed. this study also provides important technical support and a scientific basis for the assessment of pb-zn deposit and the exploration of mineral resources around the area. the calculations made in the pb-zn deposit of arregije, including 1359,118 tons of ore with a grade of 3.55. there will be 48,383 tons of pb-zn deposit in this area which will be promising for its extraction and further prosperity of the region.
