| Muzhugou Gold Deposit is located in Laoling metallogenic belt on the eastern side, in the Yalu River fault zone, formed in the late Yanshanian period, it is found that is Laoling metallogenic belt for the exploration and breakthrough, but the research degree is relatively low.In the mining area, there are 8 main ore bodies, the highest grade 31.31g/t, theⅠ-1 ore body is the main body, which is located in the Ⅰ# mineralization alteration zone. The ore type is tectonic altered rock type and quartz vein type. Ore minerals are mainly electrum, pyrite, pyrrhotite, gangue minerals are chlorite, sericite, ore structure mainly it shaped granular, automorphic, hypidiomorphic and. The wall rock alteration is mainly silicification, sericitization, chloritization and carbonatization. The mineralization period is divided into three stages: pyrite quartz stage, quartz pyrite stage, gold polymetallic sulfide stage, pyrite quartz carbonate stage.Muzhugou Gold deposit genesis and Yanshanian hydrothermal activity are closely related. Its formation is controlled in regional NNE to The Yalu river fault and its secondary faults, the ore-forming hydrothermal migration and precipitation provides the channel. The ore body mainly along the crack production in NE to the secondary faults. The Yalu River fault metallogenic belt. Gold deposit, the main ore bearing rock is early Proterozoic Dalizi formation, the area of containing the initial ore source rock gold and gold, in the study area the known ore(pulse) body distribution in which. The source of mineralization may also be the source of the mantle.The study of fluid inclusions shows that the value of the Muzhugou gold deposit in the sow is from 170 to 297.4 degrees C, and the value is 139.4 degrees C to 200 c, and the mean value is 183. Salinity range of 0.7- 7.99wt%NaCl, more concentrated in the 1-5wt%NaCl, the average value of 3.44%NaCl, and the mixing of the atmospheric water. The average density of 0.91 g/cm fand display characteristics of Muzhugou Gold Deposit, sow fluid with low density. The calculation results show that the shallow depth of mineralization(4.69 ~ 7.25km).To discuss the importance of the diorite porphyrite formed in Late Triassic to gold metallogenic space on the Muzhugou Deposit. The diagenetic process of the early mineralization, activation of the hydrothermal solution of the filling channel in Yanshan. Magma derived from the crust mantle mixing, formed in the paleo Asian Ocean after the closure of the orogenic extensional environment.Through the study of Muzhugou Gold Deposit Geological Features and geophysical and geochemical. Extraction of the Muzhugou Gold deposit prospecting information proposed Muzhugou Gold Deposit is a medium low temperature hydrothermal type gold deposit, the metallogenic prediction of the deep and periphery. |
