Chemofacies of Qom formation in the Northwest of tafresh dased on geochemical data

In order to investigate the analysis of chemical facies of the Qom Formation in the northwest of Tafresh based on geochemical data, 28 rock samples were chosen, of which 16 were selected and subjected to primary mineralogy analysis. A study of the examined area and Section type and other areas demonstrated that Permian semi-polar limestones are found in the modern-day tropical aragonitic range and are near the total carbonate samples of the modern-day temperate regions of Tasmania. This is due to the mixed calcite-aragonite mineralogy in these limestones. The measurements of the investigated region and standard areas showed that some samples are in the range of Permian cold water limestones with calcite mineralogy and have a low correlation value.

Charts 2 to 9 indicate the elemental changes of the study area were widely expressed and measured with benchmark areas. As a result, it was found that the study area was located in the shallow part of the carbonate basin.
