There are wide spread Cenozoic volcanic rocks in Tengchong (CVRT), Yunnan province, SW China. These rocks comprise three rock types: basalt, andesite (dominant type) and dacite. Most samples are sub-alkaline, and among the sub-alkaline rocks, most are high-K calc-alkaline. These rocks have a SiO 2 range of 49.1 wt.% to 66
The purpose of this study is to examine the shearing and crushing characteristics of the T-L rock mass. A series of large-scale shear tests were performed on the reconstituted T-L rock mass …
The type of rock you plan to focus on processing in your operation will dictate the types of rock crushers you'll need to include in your crushing circuit. The more you know about the type of rock you wish to crush and what its end-use will be, the easier it is to choose the best equipment to achieve your project goals.
The study area is located in the coastal Pacific metallogenic domain-Upper Yangtze (continental block) metallogenic Province-the south-central Yunnan metallogenic belt (Fig. 1).The regional basement is a double basement: the Paleoproterozoic basic volcanic rocks + epimetamorphic rocks, and the fold basement of Mesoproterozoic epimetamorphic rocks.

The Li-rich clay rocks of Middle Permian Liangshan Formation in central Yunnan Province are distributed in the mudflat zone of estuary and coastal plain swamp area on the east side of central Yunnan archicontinent during Liangshan Period. The clay rocks of Liangshan Formation are composed of four lithologic types, including gray-greyish brown ferric bauxite rock, grayish …
The detailed study on petrochemistry and geochemistry shows that meta-volcanics from Huimin and meta-basalts from Suyi belong, respectively, to different volcanic series. The former is of non-alkalic volcanic series and the latter is of straddle A-type alkslic series. Based on their geochemical characteristics of REE, LIL, HFS and Nd, Sr isotope …
Type B inclusions are composed of a liquid aqueous solution plus water vapor (LH 2 O + VH 2 O; Fig. 4a–d). In the samples we studied, type B inclusions are more abundant than the type A and the two types of fluid inclusions generally appear separately. The Type B inclusions are about 70 to 90% filled by liquid phase (Fig. 4a–d).
The Xiuwacu deposit is a typical granite-related quartz-scheelite-molybdenite vein type deposit hosted within sandstones and sandy slates in the southern Yidun Terrane, western Yunnan Province, China. The Xiuwacu complex comprises the Late Triassic biotite granite and Late Cretaceous monzogranite porphyry (MGP) and aplite granite.
