Zoogeographical analysis of the land mollusks from Shaanxi province, china, with description of two new species ( gastropoda: Pulmonata: stylommatophora) 陕西省陆生贝类的动物地理学分析及二新种记述(腹足纲:中腹足目:柄眼目)
Few species, low biomass and lack of blue green algae, Gastropoda, Lamellibranchia and Crustacea are most notable characteristics distinguished from general neutral and alkaline lakes. 湖泊生物种群少且生物量低,缺失蓝藻和腹足类、瓣鳃类、甲壳类动物等为其区别于一般中、碱性湖泊最显著的特点。
Detailed biostratigraphic study reveals that the sequence could contain 3 Ostracoda assemblages, 3 Lamellibranchiata and Gastropoda assemblages and 8 sporopollen assemblages, whose ages are discussed on the basis of radioactive dating. 通过详细的生物地层学研究,共划分出3个介形虫化石组合带、3个瓣鳃类及腹足类化石组合带和8个孢粉组合带,结合各组同位素年龄数据,对其形成时代进行了探讨。
