Abstract

. In the past decade, the increase in the number of palynological works in Mozambique documents the significance of palynology in dating the late Palaeozoic basins in this region of southwestern Gondwana. The new information gained mainly from the study of the Moatize-Minjova Coal Basin is the basis for a better understanding of the regional biostratigraphy, as well as of palaeoenvironmental and palaeoclimatic conditions during the Permian. Here we provide a review on the Permian palynostratigraphy and its implications for lithostratigraphic correlation of Lower Karoo basins in Mozambique. The new biostrati-graphic information leads to the conclusion that an age update for the lithostratigraphic units established for the Lower Karoo in Mozambique (Vúzi, Moatize, and Matinde formations) is most needed. The Cisuralian palynological association in Mozambique is characterized by long-range taxa recorded since the middle Cisuralian (Sakmarian to Artinskian) ( Alisporites spp., Cannanoropollis spp., Horriditriletes spp., Laevi-gatosporites spp., Potonieisporites spp., Protohaploxypinus spp.). Several first occurrences are also recorded in the late Cisuralian (Kungurian) (e. g., Cirratriradites africanensis , Marsupipollenites triradiatus , and Vittatina spp.). The Guadalupian association is mainly characterized by taxa that extend their range since the Cisuralian (e. g., Alisporites spp., Cirratriradites africanensis , Guttulapollenites hannonicus , Horriditriletes ramosus , Kraeuselisporites enormis , Lueckisporites virkkiae , Limitisporites monstruosus , Marsupipollenites striatus , M. triradiatus , Pakhapites fusus , Platysaccus papilionis , Thymospora pseudothiessenii
莫桑比克下卡鲁群二叠纪地层学和孢粉学——2020年展望
在过去的十年里,莫桑比克孢粉学著作数量的增加证明了孢粉学在确定冈瓦纳大陆西南部晚古生代盆地年代方面的重要性。主要从Moatize Minjova煤盆地的研究中获得的新信息是更好地了解二叠纪区域生物地层学以及古环境和古气候条件的基础。本文综述了莫桑比克下卡鲁盆地二叠纪孢粉地层学及其对岩石地层对比的意义。新的生物地层信息得出的结论是,最需要对莫桑比克下卡鲁(Vúzi、Moatize和Matinde地层)建立的岩石地层单元进行年龄更新。莫桑比克的Cisolarian孢粉组合的特征是从Cisolaria中期(Sakmarian到Artinskian)以来记录的长程分类群(Alisporites spp.、Cannanoropolis spp.、Horriditrietes spp.、Laevi gatosporites spp.、Potonieisporites spp.、Protohlopoxypinus spp.)(例如,Circratriradites africanensis、Marsupillonites triradiatus和Vittatina spp.)。瓜达卢皮属的主要特征是自Cisuralian以来扩展其范围的分类群(例如,Alisporites spp.、Circratriradites africanensis、Guttulapollenites hannonicus、Horriditrietes ramosus、Kraeuselisporites enormis、Lueckisporites virkkiae、Limitisporites monstruosus、Marshupipolenites striatus、M.triradiatus、Pakhapites fusus、Platysaccus papilionis、Thymospora pseudo-thiessenii

期刊介绍: Newsletters on Stratigraphy is an international, peer-reviewed journal with a focus on stratigraphic issues that are relevant for a broad geoscientific community. Papers published in Newsletters on Stratigraphy use (and ideally integrate) stratigraphic methodologies from a wide field of disciplines, including (but not limited to) biostratigraphy, chronostratigraphy, chemostratigraphy, and magnetostratigraphy. The results have implications for paleogeographic reconstructions, paleoceanography, paleoclimate, biotic evolution, basin development, or regional and supraregional correlation. Papers published in Newsletters on Stratigraphy comprise original research articles, background information on ongoing work of e.g., the International Stratigraphic Commission (ICS) and the International Subcommission on Stratigraphic Classification (ISSC), and review articles. There are no page charges for the publication of regular papers.
