| The Ore-forming Geochemical Mechanism of the Zhaojikou Pb-Zn Ore Deposit, Anhui Province |
| Geochemical exploration has been playing a very important role in the field of mineral resources pros-pecting and evaluation. At present, the mining indus-try has a clear demand that the study of geochemical exploration should return to the focus of the basic theory. The multi-dimensional anomaly system (MAS) is one of Chinese responding in this regarding. MAS means that anomalies of many attributes which formed in different ways during a specific ore-forming period co-exist sequentially in space and indicate the ore bodies/deposits progressively. The spacial structure and formation processes of multi-attribute anomaly in MAS are the foundation to study ore-forming geochemical mechanism and pros-pect new ore bodies/deposits. Meanwhile, it is also the cutting edge of exploration geochemistry. In this dissertation, we selected the Zhaojikou epithermal Pb-Zn ore deposit, Anhui Province, as the object of study. First of all, the method of mass-transfer balance was used to study the elemental mobility in the ore- forming process, to construct an ore-forming anomaly model, and to reveal the ore-forming geochemical mechanism. Then, the distributions of elements of interest in different levels were visualized to show the ore prospecting direction in the deep. Fi-nally, fractal model and PCA and factor analysis based on the compositional theory were used to study the distributions, anomalies, and controlling factors of elements of interest in the surface to help the geo-chemical exploration projects in the periphery of the Zhaojikou District. |
