中文摘要：
在柴北缘超高压变质带东端的沙柳河地区蛇绿岩剖面中,首次发现了与蛇纹石化方辉橄榄岩共生的异剥钙榴岩。该异剥钙榴岩主要由钙铝榴石、透辉石、绿泥石、碳酸盐及少量葡萄石和黝帘石组成。异剥钙榴岩通常被认为是洋底变质作用的标志性产物。因此,此异剥钙榴岩的确定,为柴北缘超高压变质带曾经存在过洋壳俯冲提供了又一证据。
英文摘要：
Rodingite,coexisting with serpentinized harzburgite,was found in the Shaliuhe ophiolite sequence,North Qaidam UHPM belt.It is mainly composed of grossular,dioposide,chlorite,carbonate and minor prehnite,zoisite.Rodingite is a typical product of ocean-floor metamorphism.The Shaliuhe rodingite is the second evidence for the oceanic subduction in North Qaidam UHPM belt.
