在本研究中，Mojen以北的farahzad地区、Shahroud地区和Mojen以东的Darkhaniab地区的晚白垩世沉积环境和相的确定被称为野外和实验室研究。选取2个剖面进行研究，共获得110个样品，共发现潮汐带、泻湖相带、堰洲岛相带和开阔海相带沉积的18个相。针状生物碎屑砂岩/包屑岩2。生物碎屑wackestone 3。生物碎屑泥粒灰岩4。棘皮生物碎屑灰岩5。棘皮动物内碎屑灰岩6。内碎屑颗粒岩7。棘皮类内碎屑石8。棘皮生物碎屑颗粒岩内碎屑生物碎屑粒岩红藻棘皮颗粒岩11。混合颗粒岩12。红藻灰岩/粒灰岩球粒生物碎屑包屑岩/颗粒岩内碎屑生物碎屑灰岩球粒千层虫科泥质岩/灰岩16。Pelloid粒状灰岩17。石灰泥岩18。Calcareous sandstone. Finally, by mention of variety, categories and survey of identified facies sedimentation environment of studied carbonate sediments zone can be named as a carbonate rimmed shelf.
