9520723 Seyfried Title: Halogen (C1, F) exchange and C1 isotope fractionation during fluid-mineral equilibra: experimental calibration of a new tool to study subseafloor hydrothermal systems Seawater circulates through the ocean crust and interacts with minerals there and leaves chlorine (C1 and flourine (f) behind. This is known from minerals that have been recovered from the ocean floor. The amount of C1 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 C1 and F in the fluid, and the amount of C1 and F deposited in the minerals is not known. The investigators plan to use laboratory experiments to determine how temperature and other conditions control C1 and F in minerals. This can then be used to interpret the conditions of the formation of the ocean crust.

小行星9520723 职务名称：流体-矿物平衡期间卤素（C1，F）交换和C1同位素分馏：研究海底热液系统的新工具的实验校准 海水在洋壳中循环，与矿物质相互作用，留下氯（C1）和氟（f）。 这是从海底发现的矿物中得知的。矿物吸收的C1和F的量可能与海底的条件有关，但这些条件（如温度）与流体中C1和F的丰度以及矿物中沉积的C1和F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C1和F。这可以用来解释海洋地壳的形成条件。
