Cretaceous deep-water paleoceanography is still in an early stage, since stable isotope analysis and geochemical data from calcitic benthic foraminifera are generally unavailable owing to an unusually high calcite compensation depth, and since the use of organically cemented deep-water agglutinated foraminifera as tracers is still insufficiently exploited.
深海环境深水胶结有孔虫的分布主要取决于碳酸盐可利用状况、原始生产的输入通量、深水交换、环境波动(深海洋流、浊流和快速沉积事件)和底层沉积类型,因此对于重建深海环境具有非常巨大的潜力。
