项目摘要

Assimilation of igneous, metamorphic, and sedimentary rocks by basalt magma is an unavoidable consequence of volcanic activity, and the presence of xenoliths (foreign rock fragments) in ocean island and propagating ocean rifts is evidence that assimilation does occur during oceanic volcanism. The process of assimilation is poorly understood and whether melting, disintegration, or diffusion into or out of the material being assimilated is the dominant process will depend on the type of material being assimilated, on the kinetics of magma interaction with that material, and on the temperature and composition of the magma. The experiments supported here will investigate the first of these problems; the melting, disintegration, or diffusion from various mantle minerals and alteration minerals, when placed in contact with molten basalt. The products of the experiments will be chemically analyzed by electron microprobe and isotope dilution mass spectrometry. Preliminary experiments have produced unexpected and interesting results, and further work will determine the importance of assimulation to the major and trace element chemistry of seamount, ocean island, and propagating rift basalts. This project will be supported at $120,470 for 2 years.
玄武岩岩浆对火成岩、变质岩和沉积岩的同化作用是火山活动不可避免的结果,洋岛捕虏体(外来岩石碎片)的存在和扩展的海洋裂谷证明同化作用确实在海洋火山作用期间发生过。人们对同化过程了解甚少,至于被同化物质的主要过程是熔化、解体还是向外扩散,则取决于被同化物质的类型、岩浆与该物质相互作用的动力学以及岩浆的温度和成分。这里支持的实验将研究第一个问题;熔融:当与熔融玄武岩接触时,各种地幔矿物和蚀变矿物的熔化、解体或扩散实验产物将通过电子探针和同位素稀释质谱进行化学分析。初步的实验已经产生了意想不到的、有趣的结果,进一步的工作将确定同化对海山、海洋岛屿和扩展裂谷玄武岩的主元素和微量元素化学的重要性。该项目将获得120 470美元的资助,为期两年。
