Annotation:

During the Triassic along the margins of the opening Neo-Tethys ocean processes developed that contributed to the formation of many stromatolite buildups. Recently, they have been studied in sufficient detail in Israel, but in the next Syria, they were practically not studied. Stromatolites are among the first biogenic sedimentary formations since the appearance of life on Earth and were widespread in certain periods of its geological record. The study of various forms and structures of stromatolites often sheds light on the nature of the ecological and physiographic settings of the past. This paper presents the results of analysis of stromatolite found in Middle Triassic deposits from the Palmyra Basin in Syria. Its main feature, distinguishing it from the currently known Phanerozoic analogues, is the primary dolomitic origin, which already makes it related to Precambrian stromatolites. Thus, the settings of the Middle Triassic within the Palmyra basin could have properties that were completely unique for that time.
