| Geological and Structural Characteristics of the Linglong-Jiaojia Type Gold Deposits and Factor Analysis of Their Metallogenic Tectonic Physicochemical Parameters--Exemplified by the Fushan Gold Deposit |
| Based on the study of geological and structural characteristics of the Linglong gold ore field, this paper has set up the me tallogenic model of Linglong Jiaojia type in this area, carried out 1∶2 000 tectono deformation facies mapping of ore source rocks in the Fushan gold district, put forward the concept of Mineralization Trading Degree(MTD) and calculated the extensive tectonic physicochemical parameters of water rock system with 15 parameters computed by factor analysis. The result indicates that their contributions to mineralization are in decreasing order of pH, average temperature, tectono additional hydrostatic pressure, p s, p min ,CO 2/H 2O,lg f CO 2 ,lg f O 2 ,F -/Cl -,and Na/K. |
