Chemical and Physical Consequences of Magma Injection in Submarine Hydrothermal Systems: Insights from Mathematical Modeling

9731494人这个项目涉及开发一种新的数学模型，能够描述浅部岩浆室附近的大洋中脊系统中的海水循环。该模型的一个独特之处在于，它能够描述高温下的海水沸腾和岩盐沉淀。该模型将用于研究沿东太平洋隆起在北纬9-10度的大洋中脊喷口系统的化学和同位素演化。这个喷口系统是在一个浅层岩浆体侵位后不久发现并取样的；在过去的几年里，由于海水沸腾，它的成分和温度发生了巨大变化。

9731494 Person This project involves the development of a new mathematical model capable of representing the circulation of sea water through mid-ocean ridge systems near shallow magma chambers. A unique feature of this model is its ability to represent seawater boiling and halite precipitation at high temperatures. This model will be used to study the chemical and isotopic evolution of a well studied mid-ocean ridge vent system at 9-10 N along the East Pacific Rise. This vent system was discovered and sampled shortly after the emplacement of a shallow magma body; its composition and temperature have changed dramatically over the past few years due to seawater boiling.
