Cocoa Tall zinc Geological Characteristics and Genesis of

ORE and Lower Devonian Kang City Rail Castle Group volcanic activity on the sub-group of closely related ore bodies and distributed by the volcanic layer control. Ore bodies are mainly located near the center of volcanic activity in the volcanic depression center, including moving production in the two volcanoes of the volcanic gap asked a normal sedimentary layer. Deposit significantly affected by post-tectonic, intrusive rocks, and metamorphism, resulting in folding parts of the site and 8 faults in Xinjiang Nonferrous Metal Mining 2002 Copper Mountain copper-polymetallic deposits in the northern section of Characteristics and Causes of the three Kim Joo Xiao Qinghua (Xinjiang Nonferrous Bureau of Geological Exploration Brigade 704 Hamilton 839 000) Abstract the northern section of the system iIi pot head the ball more than j \loss iii cover music brand-Shí Keywords fracture, multiple mining spider 0 instep fire only iil Jl】 channel and l steel mining area geology is more important in eastern Xinjiang metal into one of the regions, the area is a tectonic position of the ancient plate Junggar Bogda North Tianshan arc-basin with a total Hare Creek late Mesozoic island-arc East, the region exposed F major stone embedded systems Yamansu second subgroup of a group of volcanic rocks and sea-oak normal quiet l rocks, regional folds, faults, the overall structure nearly east-west main line,[link widoczny dla zalogowanych], where the main east-west shear field f faults of secondary faults and anticline subvolcanic rocks and volcanic dike call the main channel + from the hydrothermal Li Qiu Wang found out that throwing excellent points about structure forming the background. coupled with the Variscan r} {frequency of magmatism, and associated volcanic Tut found in the same period expanded, branching units and the complex transformation of mineral crystals and other features of coarsening . 22 mineralization in the Devonian period model, with regional crustal extension, fault activity, the impact of global sea level rise,[link widoczny dla zalogowanych], Mai Zi Tong gradually into the basin.

With the level of geological research to improve non-coral, the western part of Japan has formed a hill zinc deposit, northern section of copper deposit box J Yu, eastern distribution pattern of copper mineralization points. In the previous comprehensive study has been to Taiwan, physical, chemical, remote sensing data Based on the author based on the work of 2.3 years later tectonic movements and magmatic activities of regional metamorphism and tectonic movement that suffered r metamorphic deposits, deformation transformation, causing multiple secondary ore body folds, resulting in a significant expansion of compressed ore; the original layer ambiguous structure of striated ore, there a small number of brecciated, stockwork structure; ore minerals (galena, sphalerite) size increases,[link widoczny dla zalogowanych], a large number of pyrrhotite, overall the ore rich. Mine South East (0 ~ 4o line) near the end of the syncline south east turn, was uplifted eroded, small deep ore body extension; the middle (7 to 73 lines) F is a trap, depth by her husband, forming a large space. exploration prospects. 24 deposit into a garden type summary Devonian Early Devonian, especially after the split rate in the shallow sea areas, coastal environment, geologic events frequently repeated movements dynamic and constantly visiting the area of volcanic activity in) 【i steady turbulent state, which is creating the volcanic eruption in the region sank more than rotating foot mechanism Peru,[link widoczny dla zalogowanych], and the formation of a cocoa tal characteristics of lead-zinc deposits of the geological and geographical conditions for and accounted for. Therefore, cocoa Tal clamp genetic type of zinc deposit, submarine volcanic exhalation should - lead-zinc deposits bed type metamorphism. that the submarine sedimentary exhalative sedimentary ore deposits in metamorphic transformation.
