摘　　要：对西南极菲尔德斯半岛早第三纪火山岩岩石学、地球化学特征及岩浆作用过程的具体分析表明，其岩浆演化过程是岩浆系统与周围环境（介质）进行能量和物质交换的热能耗散过程，具有动态平衡和阶段性的特点。岩浆结晶的多级复合结构和高位岩浆房中的分带构造，是岩浆作用非平衡过程的自组织现象。Volcanic geological,petrological and geochemical characteristics of the tertiary volcanic rocks from the Fildes Peninsula,West Antarctica,show that magma evolution was a process of dissipation of heat energy exchanged energy and mass occurring between the magma system and its surrounding environments, and with the feature of dynamic equilibriumand periodicity (stage). The multi grade complex texture of magmatic crystallization and the zonal structure in the high level magma chamber are the self organization phenomenons in the nonequilibrium process of magmatism, and the self organization phenomenons are also called the dissipative structure.
