Halogen (C1, F) Exchange and C1 Isotope Fractionation During Fluid-Mineral Equilibria: Experimental Calibration of a New Tool to Study Subseafloor Hydrothermal Systems

海水在洋壳中循环，与那里的矿物质相互作用，留下氯(Cl)和氟(F)。这一点是从从海底开采的矿物中得知的。矿物吸收的氯和氟的量可能与海底的条件有关，但这些条件之间的关系，如温度和流体中的氯和氟的丰度，以及矿物中沉积的氯和氟的量之间的关系尚不清楚。研究人员计划利用实验室实验来确定温度和其他条件如何控制矿物中的氯和氟。然后，这些数据可以用来解释洋壳形成的条件。

Seawater circulates through the ocean crust and interacts with minerals there and leaves chlorine (Cl) and fluorine (F) behind. This is known from minerals that have been recovered from the ocean floor. The amount of Cl and F that is taken up by minerals is probably related to the conditions within the sea floor, yet the relationship between these conditions, such as temperature and the abundance of Cl and F in the fluid, and the amount of Cl and F deposited in the minerals is not known. The investigators plan to use laboratory experiments to determine how temperature and other conditions control Cl and F in minerals. These data can then be used to interpret the conditions of the formation of the ocean crust.
