Th. pres.nt work aimed to document th. facies.development and s.dimentology of th. Ragh.ma carbonates.expos.d along th. eas.ern coas.al plain of th. red s.a, north.es.ern s.udi Arabia. Four s.ratigraph.c s.ctions.were meas.red and s.mpled(D1–D4) and th.n s.ctions.and major and trace element analys.s.were prepared and applied for petrograph.c and geoch.mical approach.s. Th. carbonates.were s.bdivided into th.ee s.cces.ive fore-reef, reef-core, and back-reef depos.tional facies. s.ndy s.romatolitic bounds.one, microbial laminites. dolomitic ooidal grains.one, bioclas.ic coralline algal wackes.one, s.ndy bioclas.ic wackes.one, and coral bounds.ones.were th. reported microfacies.types. Petrograph.c analys.s.reveals.th.t th. s.udied carbonates.were affected by dis.olution, dolomitization, and aggrading recrys.allization, wh.ch.affects.both.th. original micrite matrix and grains.or acts.as.fracture and veinlet filling leading to wides.read vuggy and moldic poros.ty. No evidence of ph.s.cal compaction, s.gges.ing rapid lith.fication and recrys.allization during early diagenes.s.and prior to s.bs.antial burial and intens.ve flus.ing by meteoric waters. mos. of th. original micros.ructure of corals.were leach.d and des.ructed. Th.s.is.indicated by th. h.gh.r depletion in s. and Ca levels.and increas. in Mg,Na, Fe, and Mn levels. es.ecially in s.ction D1, in comparis.n with.th. worldwide carbonates.
