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.

9731494人 该项目涉及开发一个新的数学模型，能够表示海水通过浅岩浆库附近的洋中脊系统的循环。 该模型的一个独特之处在于它能够代表海水 沸腾 和 岩盐沉淀 在 高温该模式将用于研究东太平洋海隆沿着北纬9 - 10度洋中脊喷口系统的化学和同位素演化。这个通风系统 不久后被发现并取样 一个浅岩浆体的就位;由于海水沸腾，它的成分和温度在过去几年里发生了巨大的变化。
