Petrochemical characteristics of Yamaghan prospect

Abstract

In this research, major and immobile minor and trace elements are used to study the petrology of Yamaghan deposit. Some major elements of least altered samples were used to classify the host rocks and their magma type. Considering slight to medium alteration of the host rock, immobile minor and trace elements of more than 110 samples were used to get more confidential results as well. The results show the high accuracy and reliability of the implemented techniques in the study area.
