摘要：The present study aimed to investigate, classify and analyze Siah Marz Kuh and Nersu cemeteries. The study adopted a descriptive-analytical method relying on historical sources. The research population consisted of the Gorgan Museum. The data were collected using both library and field studies. The results showed that the majority of headstones in Siah Marz Kuh and Nersu cemeteries were upright (vertical) and made of sedimentary river slates. The inscriptions on the headstones were written using Naskh, Nastaleeq and simple-artless scripts. The inscriptions ranged in color mostly from dark to light grey. The intaglios carved in the headstones included circles resembling the moon and the sun (as a symbol of light), single- and double-sided comb, Turbah and beads, weaving supplies such as spindle, bobbin and shuttle as well as weapons such as gun, gunpowder container, sword and daggers
