Eocene extension and magmatism in Central Iran was followed by late Eocene – early Oligocene uplift, erosion, volcanism and the deposition of the continental and evaporitic sediments of the Lower Red Formation. During the late Oligocene – early Miocene, an extensional (or transtensional) phase occurred with the deposition of the limestones and marls of the Qom Formation, followed by the evaporitic deposits or mudstones of the basal part of the Upper Red Formation. Since the late Miocene, compression has resulted in regional shortening and uplift, with the deposition of the thick, clastic‐dominated upper part of the Upper Red Formation and the overlying conglomeratic unit.

伊朗中部盆地西部的石油地质

伊朗中部始新世伸展和岩浆作用之后是始新世晚期–渐新世早期隆升，侵蚀，火山作用以及下红组的陆相和蒸发沉积物的沉积。在渐新世晚期至中新世早期，发生了伸展（或张性）阶段，沉积了Qom组的石灰岩和泥灰岩，随后出现了上红组底部的蒸发沉积或泥岩。自中新世晚期以来，压缩作用导致区域缩短和隆升，上部红组的上部以厚屑碎屑为主，上部为砾岩沉积。
