Three sections of Guri Member of the Mishan Formation in the Bandar Abbas area are investigated for foraminifera biozonation and lithostratigraphic correlation. The base of Guri Member conformably overlies Gachsaran Formation (or Razak Formation in some sections), whereas the top of the member is overlain by marls. Thirty-four foraminifer species are identified and prove the age of Burdigalian for the Guri Member in the Gery Sheikh and Anguran sections and Burdigalian–Langhan range in the Bāz section. Two assemblage zones are recognized based on the distribution range of species. Correlation to other sections shows the eastward marine progression and age change from the Burdigalian in the west to the Burdigalian–Langhian in the east of Bandar Abbas area.

对 Bandar Abbas 地区密山组古里段的三个剖面进行了有孔虫生物区带和岩石地层对比研究。古里段底部一致地覆盖在 Gachsaran 组（或某些地段的 Razak 组）上，而该段的顶部被泥灰岩覆盖。鉴定了 34 种有孔虫，并证明了 Gery Sheikh 和 Anguran 剖面中 Guri 成员的 Burdigalian 年龄以及 Bāz 剖面中的 Burdigalian-Langhan 范围。根据物种的分布范围，识别出两个聚集带。与其他剖面的相关性显示了从西部的 Burdigalian 到 Bandar Abbas 地区东部的 Burdigalian-Langhian 向东的海洋进展和年龄变化。
