海相碳酸盐鲕粒形成过程的模拟实验研究
Experiment study of synthesis for marine carbonate ooids genesis
摘要
Abstract
The ooids were synthesized using the laboratory simulation of sedimentary environment,through which the process of the ooids formation and the environmental factors of influencing the ooids formation were studied.Three parameters were considered in the experiment,which are algae type,water agitation,and nucleus amount.It is found that synthesized ooids tend to have the best concentric structure and the most compact surface under hydrostatic condition and the presence of algae,indicating that quite water and the biological effect of alga are favorable conditions for ooid growth.The number of calcium carbonate crystal nucleus is also a decisive factor for the ooids formation.Based on the difference of nucleus quantity and activation energy,a kinetic study of the formation of marine calcium carbonate ooid and micrite wwas conducted as well.关键词
