Measuring of Transformation Relations of Fluid inclusion of the Narigan Iron and Manganese Deposit

Prediction of the transformation relations for minerals such as Iron and manganese bearing oxides are based on the percentage of other minerals were deposited in the iron bearing anomalies constitute one of the main aspects of geochemistry. In this article, the iron and manganese anomalies of Choghart and Narigan districts are considered. Transformation relations are obtained based on computation of the amount of an oxide with respect to another unknown oxide. The variation trends of Fe203 and MnO in different samples are considered too. Several diagrams are drawn and based on them, the transformation relations are obtained by chemical analysis of minerals occur in the deposit. The genesis (based on formation environment), the way of formation of rocks and the economical percentage of the mineral deposits with respect to the depth of sampling can also be determined. In Narigan mine, one of the best mineral that can be used for the study of fluid inclusion is quartz (because of its transparency, abundance and co-genetic with the ore minerals). For this region, the relation between the equivalent salinity of salt and temperature are studied. Fluid inclusion generally appears in the two gas and liquid phases (and sometimes solid inclusions). As the pressure on the fluid inclusion is increased the temperature difference between homogenization temperature and its trapping temperature increases.
