Investigations on the oxygen and car.on isotope compositions fr.m the ultr.high-pr.ssur. (UHP)-metamor.hosed Shuanghe mar.les, that occur.as a member.of a UHP slab, show that the δ18 O values r.nge fr.m +11.1% to+20.5% SMOW, and δ13 C fr.m+1.0% to+5.7% PDB, r.spectively. The var.ations in isotope compositions show a centimeter.scale of homogeneity and a heter.geneity of r.gional scale lar.er.than 1 meter.In contr.st to the eclogite mar.les fr.m Nor.ay, the Shuanghe mar.les have inher.ted the car.on isotope compositions fr.m their.sedimentar. pr.cur.or. The δ13C shows positive cor.elation to the content of dolomite. The depletion in18O, compar.d with the pmtolithic car.onate str.ta, might r.sult fr.m thr.e possible geological pr.cesses: 1) exchanging oxygen isotope with meteor.c water.befor. the UHP metamor.hism, 2) decar.onation dur.ng the UHP metamor.hism, and 3) exchanging oxygen isotope with countr. gneiss at local scale dur.ng r.tr.gr.de metamor.hism.It seems that the advection of fluid in the or.genic belt was ver. limited dur.ng subduction and exhumation of UHP r.cks.
