Description

Early Triassic carbonate outcrops were studied in the central sector of the Hăghimaş Syncline with regard to stratigraphy, microfacies and facies interpretation.This is the first microfacies study of these deposits. Early Triassic carbonates in the Hăghimaş Syncline are represented by two stratified successions: limestones and dolomites. The limestones overlie very rarely the detritic basal deposits (Induan) which marks the beginning of the alpine transgression. The stratified dolomites underlie frequently the Early Anisian massive dolomites. The contact between the stratified limestones and stratified dolomites is only exposed on Calu brook outcrop (the western flank of the Hăghimaş Syncline). The age of the investigated carbonates is Olenekian, based on the occurrence of Meandrospira pusilla biozone (in limestones). The foraminifera are very scarce in dolomites, represented mostly by Earlandia taxa. Microfacies data indicate the existence of a carbonate platform. The Olenekian carbonates yield a broad spectrum of microfacies types, predominantly micrites and biomicrites with foraminifera associated with echinoderms, ostracods, radiolarians, calcitized gastropods etc. These facies types are also known from the carbonate platforms in other parts of the Tethys.
