Microfacies of tel hajar formation in south-west iraq

أ‌) تم تقسيم تكوين تل الحجار في منطقة الدراسة إلى خمس سحنات دقيقة هي : 1_ Fine hiogenic dolomite facies. 2_ Sandy rich dolomite facies. 3_ Dolomite diagenetic facies. 4_ Recrystallized wackestone in microfacies. 5_ Mudsione facies. ب‌) أهم العمليات التحويرية هي إعادة التبلور و ترسيب داخل حجيرات المتحجرات. The Tel Hajar formation in the studied area has been divided into five microfacies units: 1) Fine hiogenic dolomite facies. 2) Sandy rich dolomite facies. 3) Dolomite diagenetic facies. 4) Reerystallized wackestone in microfacies. 5) Mudstone facies. Microfacies reflect shallow marine water with open Circulation in the lower part of the formation and the environment of the upper is enclosed between upper tide and tide. The most important diagenesis was recrystallization and spary calcite deposit inside fossils chambers and pores.
