| 摘 要： | 本文利用目前有关含镁方解石以及水－碳酸钙系统的研究成果，对水－含镁方解石系统的模型化作了初步的尝试；然后以该系统为核心，拓展出了一个包括气候、水文及水化学等影响因素在内的湖泊综合模型，并运用该湖泊模型定量化地探讨了湖泊中常见的由气候季节性变化所控制的、由交替富含碳酸盐和碎屑物的层系所构成的韵律沉积现象，展示了该类湖粕的水化学演化进程，证明了韵律中的碳酸盐可在每年的夏季形成

| Abstract: | This paper shows an elementary attempt to model the water magnesian calcite system by making use of the up to date achievements in the researches on magnesian calcite and water calcite system.Then,on the basis of this system,a general lake model was developed which includes climatic,hydrologic and hydrochemical conditions.The lake model is applied to the quantitative study on the phenomenon of the alternating carbonate and clastic rich rhythmic deposition in lakes controlled by seasonal climatic change.The evolution process of the lacustrine hydrochemistry producing rhythmic deposition of the above style is demonstrated in this paper.It is verified that the carbonate deposits in the rhythm might be formed in summer of each year. |
