Tepe Giyan was first excavated by French archaeologists George Contenau and Roman Ghirshman, with the support of the Musées Nationaux and the École du Louvre, in 1931-32.

The most significant motifs in this phase are pairs of birds with wings spread in the shape of a comb and rows of sawtooth patterns.

[6] The phase of Tepe Giyan I (1400 — 1100 BCE) shows that iron was still rather scarce in this site and in the areas, a Persia in general at that time, with only a few daggers, spear-heads and arrow-heads, rings and bracelets being found.

In 2011, Mr. Khaksar's archeological team discovered a unique burial specimen that had been operated on the cheeks and knees of a bronze ring skeleton of a 40-year-old man.

It bears similarities with the site of Tepe Sialk, in the same general area, and its oldest ceramics are also related to the Ubaid period in Mesopotamia.
