地质矿产部岩溶地质研究所构造地质组,最近在桂林岩溶地区灰绿色粉砂质泥岩中发现三叠纪植物群孢粉化石,这是继本纽于去年在桂林岩溶区的红色粉砂质泥岩中发现丰富的白垩纪轮藻,介形虫和孢粉化石后,对朴林岩溶地区沉积、堆积建造研究方面的又一可喜的进展。 这个植物群孢子花粉化石组合,是分两批请广西石汕开发指挥部科研所杨荣玉鉴定的。其中,有蕨类植物孢子17个种(届);裸子植物花粉24个种(属);未见被子植物花粉。孢粉中,以裸子植物占绝对优势,两次鉴定中花粉为孢粉总数的72.5%及93.7%,余为蕨类孢
Recently, the Triassic flora sporopollen fossils have been found in the grayish-green silty mudstone in the karst area of Guilin, which is the result of Benniu’s red silty mudstone in the karst area of Guilin last year In the discovery of rich Cretaceous chalcedonias, ostracods and sporopollen fossils, another promising progress has been made in the research of sedimentation and accumulation in the karst area of PuLin. The flora spore pollen fossil combination is divided into two batches of Guangxi, Shantou Development Command Research Institute Yang Rongyu identified. Among them, there are 17 species of fern spores (sessions); gymnosperms 24 species of pollen (genera); no angiosperm pollen. Sporopollen, gymnosperms accounted for absolute advantage, two times identified pollen as the total number of spores 72.5% and 93.7%, the remaining ferns spores
