زیست چینهنگاری و ریزرخسارههای سازند آسماری در حوضه زاگرس: تطابق زمانی و 38 محیطی

In this research, biostratigraphy, microfacies and paleoenvironment of the asmari formation in the fars province (tang-e abolhayat, naura anticline, south-west of firozabad, khormuj anticline), high zagros (shoorom anticline), izeh zone (mokhtar anticline), dezfulembayment (tang-e anbar sepid, dill anticline, khaviz anticline, aghajari oil field) and lurestan province (mamulan, sepid-dasht, dehluran and kabirkuh-darreshahr), werereviewed and revised for the comprehensive understanding of age and depositional environmentsthe globigerina spp.-turborotaliacerroazulensis-hantkenina and nummulitesvascusnummulitesfichteli assemblage zones (rupelian) are present in fars province. the dominated microfacies within the asmari formation of the rupelian time are bioclast planktonic, nummulitidaelepidocyclinidaewackestone-packstone, of an outer and middle ramp depositional setting. the archaiasasmaricus-archaiashensoni-miogypsinoidescomplanatus assemblage zone (chattian) is present in fars, high zagros, izeh and dezful embayment provincesthedominated microfacies within the asmari formationof the chattian timeare bioclastperforateimperforate foraminifera wackestone-packstone and mudstone, of an inner ramp depositional setting. the miogypsina-elphidium sp. 14-peneroplis farsensis assemblage zone (aquitanian) ipresent in high zagros, izeh, dezful embayment and parts of the fars and lurestan provinces. the dominated microfacies within the asmari formation of the aquitanian time are perforateimperforate foraminifera bioclastwackestone-packstone, grainstone and mudstone, of an inner ramp depositional setting. the borelismelocurdica-borelismelomelo assemblage zone (burdigalian) is present in most areas. but it slightly occurs in fars province. the microfacies of the asmari formation during burdigalian are similar to those of aquitanian. in sepid-dasht and tang-e anbar sepidsections due to presence globigerina spp. assemblage zone and planktonic foraminifera wackestone-packstonefacies, an outer ramp depositional setting is also suggested.
