The oxygen isotope data of 100 mineral pairs of wolframite and quartz in southern China, Inner-Mongolia and Hebei are collected and analyzed in this paper, and all of the data are plotted into five areas in the relation diagram among oxygen isotopes of wol framite and quartz, genetic types and ore-forming temperature of the deposits. Each of which respectively centres the same or similar deposits in genesis. Therefore, five genetic types of veined tungsten deposits can be classified, i.e. crust- type and crust-mantle...

The authors consider that mylonite is one type of tectonite which shows obvious plastic deformed features, contains marks of movement-sense and outcrops in narrow belt.Mylonitic texture and grain-size reduction should not be treated as the main criteria for recognizing mylonite. Blastomylonite is an indeterminate term causing confusion in its meaning and should be abandoned in use. It is proposed that two systems of classification of mylonite, i. e., descriptive classification and origin classification, should...

The authors consider that mylonite is one type of tectonite which shows obvious plastic deformed features, contains marks of movement-sense and outcrops in narrow belt.Mylonitic texture and grain-size reduction should not be treated as the main criteria for recognizing mylonite. Blastomylonite is an indeterminate term causing confusion in its meaning and should be abandoned in use. It is proposed that two systems of classification of mylonite, i. e., descriptive classification and origin classification, should be established. In the descriptive classification, mylonite is divided into three categories, finegrained mylonite, medium-grained mylonite and coarse-grained mylonite mainly according to the grain-size of matrix mineral. Every category could be then divided into three subcategories by adding "homogeneous", "homoclastic (homoporphyroclastic)" and "heteroclastic(heteroporphyroclastic)" to the mylonite name respectively on the basis of investigating the distributional status and size-difference between porphyroclasts. In the origin classification, mylonite is first divided into low-temperature brittle-ductile mylonite, middle-temperature ductile mylonite and high-temperature ultraductile mylonite, and then further divided into low-temperature quartz brittle-ductile mylonite, middle-temperature quartz ductile mylonite, middle-temperature quartz-plagioclase ductile mylonite, high-temperature plagioclase-Kf-feldspar ultraductile mylonite, high-temperature Kf-feldspar-pyroxene ultraductile mylonite and high-temperature pyroxene-olivine ultraductile mylonite.
