| 英文摘要 | The Jinding ore deposit is the Youngest and the only giant deposit hosted in continental sedimentary rocks in the world, and followed with interests. The Jinding fluid mineralization experienced three stages, they are quartz-sphalerite-galena, sphalerite-galena-celestite and galena-calcite-celestite-gypsum, according to the intergrowth of minerals in the Jinding ores. Pyrite occurs in each stage, and various generations of minerals can be distinguished by their occurrence, texture and assemblage relations. Rare element compositions in fluid inclusions are an important indicator of the large-scale fluid metallogenic processes because the REE patterns and rare element distributions of the fluid inclusions in minerals of various mineralization stages do not evidently change in different hosted minerals. From the first to the third mineralization stage of the fluid mineralization processes, Sigma REE (1.34 x 10(-9) similar to 6.28 x 10(-9) similar to 297.03 x 10(-9)) and LREE/HREE increased in the ore-forming fluid respectively, and the fluid system became more oxidizing, the rare element assemblage of the ore-forming fluid became more complex, the metallogenic element (zinc changing from 13.594 x 10(-9) to 29331. 810 x 10-9) was richer and richer (zinc being 0.16 x 10(-3) similar to 0.20 x 10(-3) times, 0.041 similar to 0.193 times and 0.028 similar to 0.341 times of China continental crust) in the ore-forming fluid. The fluid mineralization may be quick during the early-middle stage and slower during the middle-late stage. A mixing of a deep- and a shallow-fluid may be the essentials for the large-scale mineralization in the Jinding. |
