资源简介:

The additional tables S1 to S5 show the biostratigraphy and the quantitative analyses carried out on calcareous nannofossils from three stratigraphic sections sampled in the Tanger-Al Manzla area (“Flysch Basin” of northern Morocco): Dar Zhirou, Saf Lahmame, and Seguedla sections. The micropaleontologic analyses were performed at the Laboratory of Stratigraphy of Roma Tre University, from January 2017 to July 2019. Details on the methods followed to perform the analyses are reported in section “3. Material and Methods” of the main text of the paper. The micropaleontologic analyses allowed to distinguish autochthonous and reworked species of calcareous nannofossils. These analyses led to the recognition of the marker species and to the definition of the nannofossils assemblages characterizing the Dar Zhirou, Saf Lahmame, and Seguedla sections. The field work and the micropaleontologic analyses carried out on the study sections allow us to refer them to a Late Miocene (Tortonian-Messinian) wedge-top basin: the Tanger-Al Manzla Basin. Table S6 shows the ichnofacies recognized into the sedimentary successions of the Dar Zhirou, Saf Lahmame, and Seguedla sections, which allow us to indicate the mud-dominated successions of the Tanger-Al Manzla Basin as deposited in a deep-marine environment. The additional Table S7 shows the migration and the migration rates of the Western Mediterranean subduction-related orogen in the last 23 Myr. Table S8 compares the migration and the migration rates of the leading edge of the central Apennines and Rif Chain during the last 18 Myr.

补充表S1至S5展示了采自丹吉尔-曼兹拉地区(摩洛哥北部复理石盆地(Flysch Basin))3个地层剖面的钙质超微化石(calcareous nannofossils)生物地层学与定量分析结果,这3个剖面分别为Dar Zhirou、Saf Lahmame以及Seguedla剖面。本次微古生物学分析(micropaleontologic analyses)于2017年1月至2019年7月间在罗马第三大学地层学实验室(Laboratory of Stratigraphy of Roma Tre University)完成。本次分析所采用的方法细节已在论文正文中的“3. 材料与方法”章节中予以说明。通过本次微古生物学分析,可区分出钙质超微化石的原地型与再沉积型种属。本次分析还识别出了标志种(marker species),并明确了Dar Zhirou、Saf Lahmame以及Seguedla三个剖面的超微化石组合特征。针对研究剖面开展的野外工作与微古生物学分析结果表明,上述剖面可归属于晚中新世(托尔托期-墨西拿期)楔顶盆地(wedge-top basin)——丹吉尔-曼兹拉盆地。表S6展示了Dar Zhirou、Saf Lahmame以及Seguedla剖面沉积序列(sedimentary successions)中识别出的遗迹相(ichnofacies),据此可判定丹吉尔-曼兹拉盆地的泥质为主沉积序列形成于深海环境。补充表S7展示了过去23 Myr间西地中海俯冲相关造山带(Western Mediterranean subduction-related orogen)的迁移活动与迁移速率。表S8对比了过去18 Myr间中央亚平宁山脉与里夫造山带前缘的迁移活动与迁移速率。
