1Partial melting of deeply subducted continental crust and the formation of quartzofeldspathic polyphase inclusions in the Sulu UHP eclogites显示文摘Two types of quartzofeldspathic inclusions hosted by omphacite and garnet were identified in the Sulu UHP eclogites. The first consists of albite, quartz, and various amounts of K-feldspar. In contrast, the second consists predominantly of K-feldspar and quartz without any albite. The presence of quart-zofeldspathic inclusions within the UHP mafic eclogites indicates that partial melting occurred in deeply subducted continental crust via mica dehydration melting reactions at an early stage of rapid exhumation. Such a melting event generated hydrous Na-K-Al-Si melts. These melts infiltrated into the mafic eclogite and were captured by recrystallizing garnet or omphacite, which together followed by dehydration and crystallization to form feldspar-bearing polyphase inclusions. Formation of silicate melts within the deeply subducted continental slab not only provides an excellent medium to transport both mobile (LILE) and immobile (HFSE) elements over a large distance, but also induces effective changes in the physical properties of the UHP slab. This process could be a major factor that enhances rapid exhumation of a deeply subducted continental slab.ZENG LingSen LIANG FengHua ASIMOW Paul CHEN FangYuan CHEN JJng 2009Chinese Science Bulletin2009,54,15:27
2深俯冲陆壳岩石部分熔融与苏鲁超高压榴辉岩中长英质多晶包裹体的形成显示文摘在苏鲁超高压榴辉岩中,石榴石和绿辉石包含两类长英质多晶包裹体.第一类由钠长石、石英和少量钾长石组成;第二类主要由钾长石和石英组成,不含钠长石.在超高压基性榴辉岩中,长英质多晶包裹体的存在进一步表明:在快速折返早期,深俯冲大陆地壳物质发生过明显的云母(钠云母或多硅白云母)部分熔融作用,形成含水的纯花岗质Na-K-Al-Si熔体.这些熔体被重结晶的石榴石或绿辉石捕获,发生脱水结晶作用,形成含长石和石英的多晶聚合体.长英质熔体的存在不仅导致流体中活动元素,如大离子亲石元素(LILE),而且是导致流体中不活动元素,如高场强元素(HFSE)迁移的重要机制.同时深俯冲大陆岩片的部分熔融作用有效地改变了岩石的物理性质,是强化深俯冲岩石快速折返的重要因素之一.曾令森 梁凤华 Paul Asimow 陈方远 陈晶 2009科学通报2009,54,13:11
