  In order to find the relationship between porphyry copper depositions with faulting systems, the Aliabad porphyry and Darre Zereshk Porphyry- Skarn ores were selected as a case studies in Uramia- Dokhtar Magmatic Belt,. In this research, discovering this correlation procedure was performed by using surface and subsurface data (i.e. drilling data as geotechnical and Cu-percentage data) from Aliabad and Darre Zereshk mine districts. The results show that RQD criteria extracted from fault zones have a good correlation with surface faults which are identified by field investigations and Remote Sensing techniques. Also, the copper enriched was observed along fault zones and therefore, the relationship between porphyry copper deposits and fault zones is approved. Manuscript profile

  Sabzsang copper deposit is located in the North of Saveh, Markazi province. In this deposit geophysical surveys and extensive surface exploration activities containing litho-geochemical, stream-sediments and trenches sampling have been carried out all over the study area. Also, five azimuthal boreholes have been drilled in a square area with dimensions of 100*115 m in the east of the deposit. In this research, lineaments in the Sabzsang deposit were first identified using the magnetometry method. To achieve the goal, the variety of required filters especially edge detection containing horizontal derivative, analytic-signal and tilt derivative was applied on the magnetic data. Afterward, relationship between the lineaments and copper mineralization was investigated using the performed direct explorations. In this regard, the qualitative correlation between the lineaments with surface copper mineralization for the entire area of the Sabzsang was determined, as the qualitative and quantitative correlation between the lineaments with copper mineralization of various surface and deep works in the area of drilling boreholes. The results of the research show that the mineral depositing in the Sabzsang area is mostly shallow, indicating a very high qualitative accordance between the lineaments and occurrence of mineral deposit in the entire surface of the area. To determine the quantitative correlation, first, 2D grid-based map of lineaments was produced. Then, the copper assay data and number of lineaments were interpolated within a same size range after the same gridding. At the end, a very weak correlation with a correlation coefficient of -0.02 was obtained between the copper assay data and lineaments in the eastern part of the deposit. This means that the mineralization has been performed in the dominant fractures but by effecting several factors, the grade of mineral deposit in mentioned locations is not necessarily high. The results of this research serve as a key and guide for decision-making to proceed the detailed exploration stage of the deposit. Manuscript profile
