Ｅｌｓｏｎ泻湖长６０ｃｍ的钻孔岩芯沉积构造、结构、颗粒性状分布等分析表明，该岩芯经历三期差别明显的沉积期，各期沉积动力环境不同。下段搬运介质单一，搬运动力较强，沉积环境相对稳定；上段搬运动力明显减弱，多源介质混合掺杂作用明显，沉积环境稳定性较差；中段为过渡期，各性状介于上、下段之间。 Analysis of the sedimentary structure, structure and distribution of grain tracts in a 60cm-long core of Elson Lagoon shows that the core experienced three distinctly different depositional stages and different sedimentary dynamic environments. The transport medium in the lower section is single, the transport force is relatively strong, and the depositional environment is relatively stable; the transport motive force in the upper section is significantly weakened, the hybrid doping effect of the multi-source medium is obvious, and the stability of the depositional environment is poor; the middle section is the transitional period, between.
