The main ore deposits localized in the area where the WNW-trending compression-shear type fault of the Indosinian epoch intersected the NE-trending tenso-shear type fault of the Yanshanian epoch. The orebody appeared in a chambered or wedged form. The mineral composition is relatively complex. On the southeastern border of the orefield there have developed intermediate-acid anatectic magmatites of the Mesozoic Era. Three-phase inclusions (Lco2, Vco2 and LNaCl-H2O) comprise over 50%, associated with vapor phase consisting of H2O, CO2, CO, CH4, N2 and H2. The ore-forming fluids can be divided into 2 stages (the early and the late). The samples are projected in the area of mixture of initial magmatic and meteoric water on the δD-δ18O diagram, suggesting two types of mineralization, i.e. the re-equilibrated magmatic-hydrothermal type and the circulating geothermal water type of a meteoric water source. The mineralization occurring in this orefield might be a superimposition of 2 tectono-magmatic activities (the Indosinian and Yanshanian movements). Therefore, it is considered a superimposed B-S type gold orefield.展开更多

As the core competitiveness of enterprises, talents can ensure the healthy and long-term development of enterprises, and human resources management is an important means to ensure the full play of talents. In human resources management, performance appraisal, as an important basis for judging the development of enterprise members, provides a basis for enterprises to explore talents and create talents, and becomes an important way for enterprises to stimulate the work vitality of enterprise members. However, to ensure the full play of performance appraisal function, it is also necessary to reasonably formulate performance appraisal methods based on the development status of enterprises, to ensure the fairness and justice of performance appraisal, and thus to promote the healthy and orderly development of enterprises. Next, the article discusses the performance appraisal in human resources management.展开更多
