The Rice Hydrothermal system is an ideal location to evaluate the relative contributions of magmatic and 18O- shifted meteoric reservoirs to a hydrothermal fluid. Three plume fluid models (no mixing, progressive upward dilution, and a spike of magmatic fluid) will be tested by measuring fluid parameters ( D, 18O, temperature, and salinity) which vary with the degree of mixing between two "end-member" fluids. The plume hypothesis itself will be tested by studying the effects of water/rock interaction in sedimentary rocks in the Rico dome.

赖斯热液系统是评估岩浆和180度漂移的大气热液对热液流体的相对贡献的理想地点。将通过测量流体参数(D、18O、温度和盐度)来测试三种羽流流体模型(不混合、逐步向上稀释和岩浆流体尖峰)，这些参数随两个“末端”流体之间的混合程度而变化。通过研究RICO穹顶沉积岩中水/岩石相互作用的影响，将检验羽流假说本身。
