Understanding how carbonate factories influence platform evolution is either based on qualitative conceptual models or quantitative numerical stratigraphic forward models. This study establishes new production depth profiles for four Cenozoic carbonate factories and uses two-dimensional stratigraphic forward models to explore how interactions between sediment production and transport within carbonate systems influence carbonate platform development. Newly established production/depth profiles are used to model photozoan and heterozoan carbonate grain associations, and the associated carbonate producing factories, and results are compared with well-studied outcrop successions. Sediment production from photozoan and heterozoan grain associations is also equalized, so that the total sediment production is the same but the depth/production profiles retain their distinctly different form. Thus, the effect of the different production profiles can be assessed. Ramps form when sediment diffusional transport rates are high relative to production rates and flat-top steep-margin platforms form when sediment diffusional transport rates are low relative to production rates, whether they are photozoan or heterozoan grain associations. The control exerted by sediment production and transport is expressed as a sediment transport–production ratio where transport ratio is a diffusional sediment transport in two-dimensions and production ratio is the total sediment production rate which is the product of a production profile that varies in depth and laterally. The transport–production ratio is a key control on the evolution and geometry of carbonate platforms. This is the case with different production profiles (both euphotic and oligophotic) and in mixed grain-size and mixed transport-rate systems. Carbonate producing factories significantly influence the rate of sediment production, the depth distribution of sediment production (production profiles), as well as the type of grain sizes produced (influencing resistance to erosion). Thus, different types of carbonate grain associations, and the associated carbonate producing factories, can produce the critical differences between carbonate platform geometries.

碳酸盐工厂如何影响碳酸盐平台形态？通过数值正向建模探索生产-运输相互作用

了解碳酸盐工厂如何影响平台演化要么基于定性概念模型，要么基于定量数值地层正向模型。本研究为四个新生代碳酸盐工厂建立了新的生产深度剖面，并使用二维地层正演模型探索碳酸盐系统内沉积物生产和输送之间的相互作用如何影响碳酸盐台地发育。新建立的生产/深度剖面被用于模拟光生动物和杂生动物碳酸盐颗粒组合，以及相关的碳酸盐生产工厂，并将结果与​​经过充分研究的露头序列进行比较。光生动物和杂种动物颗粒组合的沉积物产量也相等，这样总的沉积物产量相同，但深度/产量剖面保持其明显不同的形式。因此，可以评估不同生产曲线的影响。当沉积物扩散传输速率相对于生产率高时形成斜坡，当沉积物扩散传输速率相对于生产率低时形成平顶陡峭边缘平台，无论它们是光生动物还是异种动物颗粒组合。沉积物生产和输送所施加的控制表示为沉积物运输-生产比，其中运输比是二维扩散的沉积物输送，生产比是总沉积物生产速率，它是深度变化的生产剖面的乘积和横向。输采比是控制碳酸盐台地演化和几何形状的关键。在不同的生产概况（透光性和寡光性）以及混合粒度和混合运输率系统中就是这种情况。碳酸盐生产工厂显着影响沉积物产生速率、沉积物产生的深度分布（生产剖面）以及产生的粒度类型（影响抗侵蚀性）。因此，不同类型的碳酸盐颗粒组合，以及相关的碳酸盐生产工厂，可以产生碳酸盐台地几何形状之间的关键差异。碳酸盐生产工厂显着影响沉积物产生速率、沉积物产生的深度分布（生产剖面）以及产生的粒度类型（影响抗侵蚀性）。因此，不同类型的碳酸盐颗粒组合，以及相关的碳酸盐生产工厂，可以产生碳酸盐台地几何形状之间的关键差异。碳酸盐生产工厂显着影响沉积物产生速率、沉积物产生的深度分布（生产剖面）以及产生的粒度类型（影响抗侵蚀性）。因此，不同类型的碳酸盐颗粒组合，以及相关的碳酸盐生产工厂，可以产生碳酸盐台地几何形状之间的关键差异。
