| Deliqier area of neimenggu province was located in the central part of the Greater Khingan Range metallogenic belt, the metallogenic zone is located in the Xingan Inner Mongolia ridge metallogenic belt( GradeⅡ) ―― Pear mountain – Eluncun- Greater Khingan Range- Yanshan Variscan period iron copper molybdenum tungsten gold lead zinc metallogenic belt(Grade Ⅲ) ――Duobaoshan- Arong Qi Yanshan Variscan period copper molybdenum gold metallogenic belt(Grade Ⅳ) ――Zhalantun Arong Qi copper molybdenum gold mineralization area(Grade Ⅴ). The structure of NNE to dalainuoer- poplar, fracture chaganobo- Arong Qi deep fault, Nenjiang Balihan fault zone control. The exposed stratum is mainly Paleozoic Mesozoic group with niqiuhe and Guanghua Formation. The niqiuhe Formation as the substrate is exposed to a set of metamorphic rocks,guanghua Formation was extrusive rock, Not integrated contact, Local fault contact.In this paper, the field geological survey in the area of the right and the region is carried out.indoor analysis and combined with the results of previous studies, the regional geological background、petrology、Physical and chemical characteristics and other issues of the region of the right is studied. The geological features and metallogenic potential of the region are evaluated. Get the following understanding:(1)Deliqier area rock assemblage is mainly a Palaeozoic shallow marine facies metamorphism in the formation of niqiuhe Formation metamorphic rocks and guanghua Formation acidic volcanic rocks.Locally there is a small amount of Jurassic intrusive rocks. Field work shows that the structural fracture is often in the contact position between the two sides, and has a quartz vein intrusion, quartz veins and more yellow iron mineralization(2)The geological conditions of Dekiqier are analyzed systematically, which is a systematic study of the typical mineralization points and the ore deposits in the region. The main mineralization types in the area of the region are porphyry and hydrothermal type. The main ore-forming strata for Guanghua formation, The lithologic characteristics of Guanghua formation exists, its complex lithology, volcano produced a large number of substances, which may provide the material source for mineralization. Magmatic rocks are mainly embodied in the quartz two long rock, It was formed in the early Cretaceous, Zircon U-Pb age showed that it was formed slightly later than the lower Cretaceous Guanghua formation, Therefore, in the process of the quartz two long rock mass, it may be possible to extract the metal elements in the strata, which has brought a certain metal material composition. In terms of structure, from the view of the integrated map of the magnetic field, the magmatic rocks, volcanic rocks and some strata along the NE direction have obvious positive and high magnetic field. Therefore, the NE trending faults control the spatial distribution of magmatic rocks, volcanic rocks and some strata in the area.(3)After the analysis of the geological conditions of the ore forming in Deliqier, the geological features of the area are presented, and the geological signs of the ore forming in the area are put forward in the aspects of the construction, the structure, the Yan Jiangyan and the alteration. Combined with the area of stream sediment anomalies and geophysical anomalies, the delineation of 8 prospecting target area.(4)Prospecting target area in 8, carried out a further large-scale geological, IP intermediate gradient, soil geochemical prospecting work, and the abnormal of trenching engineering verification, preliminary evaluation of the region further prospecting, think Nuomin town and ditch Hungnam area has good prospecting potential. |
