Introduction

why you want to study?
in other words, why is it important?
- 有生物、地化、和沉积方面的地层记录变化说明早三叠世期间的海水化学特征处于波动的状态 environmental perturbation is accompanied with sedimentary record variations, biological, and geochemical variations, which has been suggested to cause protracted ecosystem recovery until Middle Triassic这正好同碳同位素波动温和coincident

3, current explanations about ooids occurrence is referred to extreme saturation state
wide distribution of ooids, however, giant ooids do not appear continuously through the Early Triassic and why?
further propose model
需要先铺垫介绍ooids can bear important information of sea water chemistry
当前对于鲕粒的解释都是说extremely saturated (implicitly ignore physical process ), but less quantified on the basis of ooids, meanwhile, also implicitly ignore the physical control from transport and erosion
ooids growth is influenced by physical, chemical, and biological control
but biological control is either changing the precipitation rate or coerosion the surface 看看liz new JSR paper
-
therefore, a model capturing both chemical and physical processes affecting ooids growth can enhance our understanding at the perturbation of ocean chemistry during the Early Triassic
minimum threshold value of saturation required for creating giant ooids, in conjunction with pCO2, it allows to further estimate coeval ALK, TOC, pH

Early Triassic ooids are big, compared to other geologic ages

早三叠世期间的海相环境波动被认为是直到中三叠世期间生命才复苏的原因（需要找找相应的文章)，saturation state作为海水的一项重要指标，影响thermodynamic potential for the mineral to form or dissolve，当然就十分的重要了
