On the basis of the achievements obtained in geological systemic investigation and analyzing geological characteristics, the authors mainly studied the strain characteristics, genesis and the age of deformation of tourmalite-quartz enclaves. Three-dimensional finite strain measurement and strain analysis of tourmalite-quartz enclaves in Yuanbaoshan pluton were carried out successively. The results show that the three strain patterns of tourmalite-quartz enclaves are plane strain (K=l), flattening strain (0 Source

The distribution of mineral veins of the Nanzhuhe tin-polymetallic ore deposit in the Dupangling district of Guangxi is characterized by "a linear variation pattern" horizontally. The ore grades of the veins are characterized by "rich in the center and hungry at the sides" horizontally and "rich upward and hungry downward" vertically. The mineralization of veins displays a pattern of "rich in tin at the north and rich in tungsten at the south" horizontally. The structure of the deposit is a "three-storied" zoning model vertically. Mineralization is structurally controlled by NNE and NW-NNW fractures, which is the most important ore-control pattern. The mineralization can be divided into two stages, that is, the major mineralization of NNE veins at the early Yanshan period and the minor mineralization of NW-NNW veins at the middle Yanshan period.
