地理位置包括“阿杜杜尼”(Adoudounian)和下寒武片岩—灰岩岩系(Se′rie schisto-ca-lcaire)的研究剖面,出露于塔鲁丹特(Taroudannt)南25公里的提厄特(Tiout)附近的前阿特拉斯山北坡上。裘伯特(Choubert)在这一地区作了大量工作,并对寒武系和前寒武系界线层的地层学研究作出了许多贡献。剖面“下钙质层”(Calcaire infe′rieur)的最上部200米是由深灰色白云岩夹少数几层白云质泥灰岩互层组成。
The geographical position includes the study profile of the Adoudounian and the Serechite-limestone series (Se’rie schisto-ca-lcaire), exposed 25 km south of Taroudannt On the northern slope of the former Atlas Mountains near Tiout. Choubert made a great deal of work in this area and made many contributions to the stratigraphic studies of the Cambrian and Precambrian boundary lines. The top 200 m of the section “Calcaire infearie” consists of a few layers of dark gray dolomite intercalation dolomitic interlayers.
