The Deep Geological Structure Of Xiuyan

With the search of surface and shallow mineral resources more difficult, to carryout deep geological studies and looking deep mineral resources is one of the maintasks of the current and future geological work. The deep mineral resources have notyet found will be one of the main sources of the21st century to meet the growingneeds of humanity. Prospecting goal should shift from shallow to the deep. Geologicalstructure and metallogenic regularity of underground become the main content. Withthe launch and implementation of the2012"Deep Geological Survey and thethree-dimensional geological mapping" project, China has entered a deep geologicalsurvey, geological modeling and deep geological prospecting era of rapiddevelopment. Geological research and prospecting work is being transformed fromtwo-dimensional era to three-dimensional era. The paper is in completed in theprocess of participating in the pilot project.Liaodong area is one of the important metallogenic zones. Xiuyan is theimportant mineral resource gathering area in the metallogenic belt area with rich jademines. Xiuyan jade is one of China’s four famous jades has rich production. In theregion there are a lot of magnesite, zinc-lead mine, graphite mine and small-scalegold and so on. Previous geological studies in Xiuyan focused on the surface andshallow, not yet carried out systematic deep geological research and geologicalmodeling work. This restricts the comprehensive understanding of geologicalcharacteristics and metallogenic regularity in Xiuyan to some extent.Carried out inXiuyan deep geological structure is conducive to recognize subsurface spaceextension form and revealing the deep metallogenic regularity. The study is based onexisting geological, geophysical research work, carried out geological data collection,field geological studies, cutting section, and non-earthquake geophysical inversion.We carried out a comprehensive study in deep geological structure of the study area,and using the block geological modeling method to build a3D model. Made the following main conclusions and results:(1) On the basis of regional geological and geophysical studies, we carried outhigh-precision gravity and magnetic and MT comprehensive geological reveals. Itreveals the deep geological structure of important formations, rock and faults in thearea. Using block modeling method constructs a three-dimensional model.(2) Mesozoic Hanjialing rock upper tends to border outside. Under Liaohe Groupnear the rock has concealed part. The formation of jade, magnesium, lead-zincdeposits in the vicinity of the rock development in Liaohe Group has closerelationship with the rock. In the process of magma intrusion, thermal and fluidgenerated create good conditions for the formation of ore deposits.(3) Get the control fault of Dayingzi basin, basement depth and other deepgeological structure information. There is a thrust fault west of the Dayingzi basin.(4) To achieve a three-dimensional display of three-dimensional geologicalmodel. Use unity3d build three-dimensional scene, create and set the left and right eyecameras. Through the manipulation of motion of the model, it can be used forrecording a left and right eye video for3D device or3D player’s. The program caneffectively demonstrate the overall and local geological information of the geologicalmodel, to highlight the three-dimensional geometry of geological objects, and toobtain a more realistic three-dimensional effect.(5) Summed up deep metallogenic regularity in Xiuyan, pointing out thefavorable stratigraphic and structural conditions for mineralization.
