7.Also found in the belt are phlogopite tremolite schist, biotite (-bearing) plagioclase amphibolite, dioritic gneiss, meta-quartz dioritic rock, fine-grained trondhjemite, adamellite, pegmatitic vein.
8.The high-pressure metamorphic rocks in northeastern Jiangxi Province include such types of rocks as jadeite-bearing aegirine-augite albite amphibole schist, jadeite-bearing aegirine-augite quartz albitite, aegirine-augite-bearing amphibole quartz albitite, aegirine-augite-bearing albite amphibole schist, winchite quartz albitite, and magnesio-riebeckite quartz albitite.
9.Scarabs were made from a wide variety of materials such as carnelian, lapis lazuli, basalt, limestone, schist, turquoise, ivory, resin, steatite, and bronze.
10.In the ocean basin spreading stage of Middle Silurian,it formed a increase metamorphic charateristics with lotrite facies→low green schist facies→hornblende facies.
11.Basic volcanic rock-banded magnetite puartzite-carboncaceous-siliceous slate(siliceous graphiuc schist)formation which should be put under Upper Archaeozoic to Lower Proterozoic Erathem is in existence in the Hekou Group.
12.Early Precambrian metamorphic crystalline basement With EW strike exposed in Yiyang-Liuyang,Hunan. Crystalline schist,layer and layer-like ultramafic rocks underwent amphibolite facies and greenschist facies. The Sm-Nd isochron ages of the ultramafic rocks are 2.6～3.028 Ga and (2.2)～1.9 Ga.
13.This study recognized that original rocks of the felsic metamorphic rocks from a key horizon (termed K and K_S) in Guangchangling Archean Banded Iron Formation are tuffaceous intermediate acidic volcanic lava for biotite-quartz-albite gneiss (K) and tuffaceous sedimentary rock for garnet-mica-quartz schist (K_S) respectively.
14.Based on the 1:50000 regional geological survey, the Sertengshan rock group is revised, involving the schist and marble of low-amphibolite to high-greenschist facies, which are distributed in middle and west Inner Mongolia.
15.The Huanglishu area is located on the east side of the Zhangbaling ultrahigh pressure metamorphic zone. The deformation structures may be classified into the basement ductile deformation zone, ductile-brittle structural schist zone and rheomorphic fold zone.
16.The new development in the metamorphic fluid research of the Catalina Schist in south California and Monviso basic eclogite in western Alps is briefly introduced in this paper. Large scale fluid flow occurred predominantly at sub forearc depths(10—50 km). LILE,LREE and B rich fluids deriving from the subduction slab migrated upwards and metasomatism happened within overriding mantle wedge in large scale.
