eclogue

4 . it is the first time that eclogite conglomerates are discovered in maotangchan and fenghuangtai formations . this suggests that ultra - high pressure metamorphic rocks in the dabie orogenic belt exhumed to the earth ' s surface in lower cretaceous . the geochemistry data indicates that the protoliths of the eclogite gravels formed in a structure setting of volcanic arc 首次在毛坦廠組、鳳凰臺組中發現了榴輝巖礫石,這一發現表明大別造山帶超高壓變質巖在早白堊世已經折返到地表,而且地球化學研究表明這些榴輝巖礫石的原巖形成于巖漿島弧構造背景。

High - pressure granulite and the coexisting eclogite and coesite - bearing ultrahigh - pressure eclogite have been subsequently found in the western syntaxis since 80s “ last century 自20世紀80年代以來,西構造結已經發現了高壓麻粒巖,與高壓麻粒巖共生的榴輝巖和含柯石英的超高壓榴輝巖。

Southeast of the ccsd main hole , there are quite a few such reflectors , implying that eclogite bodies exist in the extension direction of the surface eclogite body 在ccsd主孔東南方深部重力高部位有多個這樣的拱形反射,預示在地表陡傾榴輝巖的延伸方向還有多個一定規模的隱伏榴輝巖體。

The authors consider that high - pressure epidote - blueschist , high - pressure eclogite , and ultrahigh - pressure eclogite formed at the same time , but at different depths 認為高壓綠簾藍片巖相、高壓榴輝巖相、超高壓榴輝巖相是在同一俯沖帶內不同深度發生的同期變質作用產物。

Since eclogite and the coexisting high - pressure granulite have been found in western syntaxis , we ' ll ask whether it is possible that eclogite also can occur in eastern syntaxis 西構造結已經發現榴輝巖和與之共生的高壓麻粒巖,東構造結是否也可能存在榴輝巖呢

Measurements of physical properties indicate that the rutile - bearing eclogite , due to its very high seismic velocity and density , can produce reflections and gravity anomalies 巖石物性測定表明,金紅石榴輝巖的縱波速度極高,會產生明顯的反射與重力異常。

This paper deals with high - and ultrahigh - pressure eclogite , its occurrence , classification , petrology and mineral features and metamorphism 摘要對區內高壓超高壓榴輝巖的分布、分類,巖石、礦物特征,變質作用特征進行了系統研究。
