Melting sequence and dynamics of the major minerals of gabbro in the process of dynamic melting
动态熔融过程中辉长岩主要矿物的熔融序列及其熔融动力学研究

Two gabbro samples were studied by high temperature and high pressure dynamic melting experiment.The melting sequence and melting phenomenon of the major minerals in the gabbro were systematically studied and explained on the base of melting dynamics.Through complete analyses to melting condition and melting mechanism,we got several conclusions:(1) Under certain melting condition,orthopyroxene can be melted earlier than clinopyroxene;(2) With different melting stage and melting rate,the melting machanism is different,which causes different melting phenomenon and different production;(3) The factor of chemistry or the element metasomatism is probably important for the melting under geological condition which is very different from the melting in physics;(4) Certain melting phenomenon or melting sequence can be influenced by many kinds of melting conditions.Only when we do analysis and comparison completely,can we determine the nature of melting which can help us understand the process of geology.
