REU: Carbonate Platforms and Their Modes of Formation and Diagenesis

这笔资金将用于在大巴哈马银行的碳酸盐岩平台上钻两个洞。该钻井将在平台边缘和内部水深5至10米的自升式平台上进行，并将穿透500至1000米的沉积物。钻这些洞的理由有两个。首先，最近关于大巴哈马浅滩地下新近纪地震地层学的发现彻底改变了人们长期以来对巴哈马演化的看法。钻探将为这些想法提供检验，并检验递进脉冲与海平面相对波动之间的关系。其次，钻这些孔将提供一个独特的机会来检查平台深处地层流体的化学成分，这将提供正在发生的成岩反应的指示。

The Funds will be used to drill two holes into platform carbonates on the Great Bahama Bank. This drilling will take place from a jack-up platform situated in 5 to 10 m of water on the platform margin and interior and will penetrate between 500 and 1000 m of sediments. The rationale for drilling these holes is two fold. First, recent discoveries about the subsurface, Neogene, seismic stratigraphy of Great Bahama Bank have drastically changed long standing ideas concerning the evolution of the Bahamas. Drilling will provide a test of these ideas as well as examining relationships between pulses of progradation and relative fluctuations of sea level. Second, drilling the holes will allow an unique opportunity to examine the chemistry of formation fluids from deep within the platform which will provide an indication of the diagenetic reactions taking place.
