Major and trace element profiles as well as mineral inclusions were analyzed in garnets from massive and foliated eclogites from the low-T/high-P eclogite-facies zone in the Hong'an orogen, China. Garnets in the two types of eclogites show different core–rim zoning and mineral inclusions. At least two stages of garnet growth are evident for most garnet grains. Garnets in the massive eclogite contain...
Major and trace elements for garnet and other minerals, and U–Pb ages and trace elements for zircon (as inclusions in garnet or as matrix) were determined on thin sections of UHP eclogite from the western part of the Dabie orogen. The results provide temporal constraints on growth of garnet during continental subduction-zone metamorphism. Major elements show homogeneous distribution across garnet...
The Junggar terrane in China's Xinjiang Province sits adjacent to the Siberian craton and Kazakhstan block. A nearly 100-m thick series of high-Mg lava flows is found in a Devonian arc in the Junggar terrane. The highly porphyritic high-Mg lavas are stratigraphically in the lower part of the Middle Devonian Beitashan Formation, and are overlain by basalts and andesites. Based on the chemistry and...
