根据14C测年、有孔虫和轮藻等微体古生物鉴定、以及Rb和Sr含量测定、磁化率、粒度沉积相分析得出以下新发现,即:在藤花落遗址末期地层及其上覆地层中均未发现任何与海相环境有关的有孔虫,在07LTT1探方中发现25颗淡水环境的左旋目轮藻.其中,龙山文化晚期地层之上的第2层有22颗;在两处探方龙山文化晚期地层之上的第2层还发现5颗植物种子及41粒真菌孢子,同时发现大量碳化根孔、植物种子外壳和根茎等;另发现,藤花落遗址末期地层和其上方的文化间歇层沉积物粒度概率累积曲线呈明显的河流沉积三段式曲线;藤花落遗址消亡之时该处两个探方地层Rb/Sr值均较高.以上均可表明,藤花落遗址的消亡与海侵无关,4.2kaBP左右龙山晚期文化应是在经历较长期的陆地水患事件后才彻底被毁灭的.
Based on the 14C dating, microfossil identification of foraminifera and charophyte, and the determination of Rb and Sr contents, magnetic susceptibility and granular sedimentary facies analysis, the following discoveries were made: that in the late stage of Tenghuaoluo Formation and its overlying strata No foraminifera related to the marine environment was found, and 25 freshwater aquatic Lhybridites were found in 07LTT1 exploration sites, of which 22 were in the second layer above the Longshan Culture Late Stage, On the second layer above the Late Longshan Culture strata, five plant seeds and 41 fungal spores were also found on the 2nd layer of Late Longshan Culture. A large number of carbonized root holes, plant seed husks and rhizomes were also found. On the other hand, The probability cumulative curve of the granularity of the intermittent sediment shows a three-stage curve of river sedimentation, and the Rb / Sr values of the two exploration sites are high at the time of the Decline of the Decantry. Since nothing was related to transgression, the late Longshan culture of 4.2kaBP should be completely destroyed after experiencing the longer-term land-flooding incident.
