A Servo-Controlled Apparatus for Mineral and Rock Deformation with High Precision Strain Measurement System

该合同提供部分(50%)资金，用于购买带有伺服控制执行器的高温变形系统。该仪器将在明尼苏达大学地质和地球物理系安装和运行。该大学承诺为该设备提供剩余50%的购置费用。该设备将被安装在明尼苏达大学一个新的矿物和岩石变形实验室中。将研究岩石和矿物的韧性变形和变形微结构的基础材料科学研究。具体的研究课题将包括地幔致密氧化物的塑性流动特性，包括钙钛矿和石榴石，以及橄榄石和钙钛矿中极低应变的瞬时蠕变。这样的实验为地幔的塑性流动提供了实验室模拟。

This award provides partial (50%) funding to acquire a high- temperature deformation system with a servo-controlled actuator. The apparatus will be installed and operated in the Department of Geology and Geophysics at the University of Minnesota. The University is committed to providing the remaining 50% of the acquisition cost for this equipment. The equipment will be incorporated in a new mineral and rock deformation laboratory at the University of Minnesota. Fundamental materials science studies on ductile deformation and deformation microstructures of rocks and minerals will be studied. Specific subjects of research will include the plastic flow properties of dense oxides of the mantle, including perovskites and garnets and the very low strain transient creep in olivines and perovskite. Such experiments serve to provide laboratory analogs to plastic flow of the Earth's mantle.
