Abstract

The iron ore deposits of the Bafq district are associated with volcano sedimentary rocks and shallow depth intrusions. The Se–Chahun Iron Ore mine is containing two major groups of ore bodies called the X and XI anomalies. One of the important plutonic rocks in the study area is Narigan granites have two type; first type granite is white to gray leucogranite with a different grain size and second type granites are a pale-pink and have a medium-grained size. Second type of granite is intruded between first type granites and the study of textures show that first type granite is formed in deeper levels. Other important litho-type is Pyroxene gabbros, in the thin section this rocks contain plagioclase (Alb) anhedral pyroxene (augite). That is crystallized between plagioclase spaces and has an ophitic texture.
