Systematic measurements of hydrogen isotopes and total water contents were carried out for metamorphic minerals from ultrahigh-pressure (UHP) eclogite, amphibolite, schist and granitic gneiss in continuous core segments from the main hole of the Chinese Continental Scientific Drilling (CCSD) project in the Sulu orogen. Together with previous studies of both outcrop and drilling samples, the results...
Oxygen isotope studies were carried out for ultrahigh-pressure metamorphic rocks from the main hole of the Chinese Continental Scientific Drilling in the Sulu orogen. The samples of interest include various types of lithology (mainly eclogite and gneiss) in a depth of 200 to 4000 m, containing five continuous core segments between contrasting lithologies. The results show a large variation in δ ...
There are two types of gneisses, biotite paragneiss and granitic orthogneiss, to be closely associated with UHP eclogite at Shuanghe in the Dabie terrane. Both concentration and isotope composition of bulk carbon in apatite and host gneisses were determined by the EA-MS online technique. Structural carbonate within the apatite was detected by the XRD and FTIR techniques. Significant 13 ...
