The doctoral dessertation title of The Prospecting information integration and investigation target area optimal in Lao Junshan tin zinc polymetallic minerogenic region is selected based on the School business cooperation project"The Prospecting information integration and investigation target area optimal and research in Lao Junshan tin zinc polymetallic minerogenic region and the three-dimensional visualization mathematics-economic research of tin-zinc polymetallic deposit in Manjiazhai, Dulong, Maguan(contract serial number:6193).Since the reform and opening, with the rapid development of economy, it is growing day by day to our country demand of the mineral resource, but now the resource guarantee degree of main ore kinds of our country is quite low, and the situation of mineral resource is very severe, so it has already severely threatened the economical security and the social stabilization of our country. To change the situation, we must depend on the progress of science and technology, and research actively the new and more effective mineral resource prognosis system of united modern metallogenic prognosis theories and high-tech, to advance whole the level of the mineral resource survey and estimation and the ability of scientific prognosis of our country, to search and find new mineral resource kinds and types, to increase the reserve of mineral resource, to provide the resource guarantee for the secure, highly effective and continual economical development of our country.On the based of the demand of the item, to aim at the front of the mineral industry and the geological survey industry of our country, to applicate the principle and method of digitized deposit,carry on the integration to th multi-dimensional prospecting information. On this foundation,to adopt the method of the comprehensive information matallogenic prognosis and the computer and the high-tech (GIS and the special software of the mineral industry), the doctoral dissertation carried through the research of the comprehensive information matallogenic prognosis and optimal investigation target area in Lao Junshan tin zinc polymetallic minerogenic region.In the premise of the full reference and absorption to the research results, we has developed the widespread field and underground geological investigation and the office synthetic research work, mainly includes:the macroscopic and the microscopic geological features research of deposits, the synthetic research of all kinds of isotope datum, the types of deposits and the discussion of the genetic model of deposits, the analysis of the geological, geophysical and geochemical characters of deposits and the research of the comprehensive information prospecting model, the analysis of the factors of control mineralization and the prospecting criteria, the research of the comprehensive information metallogenic prospecting based on the GIS space analysis, the research of the prospecting of the deposit depth and nearby based on the digitized deposit and so on, mainly obtains the achievement through the above research:1. Through the ore deposit geology research, unioned the mineral petrology character of metamorphic rock,having carried on the metamorphic rock restoration, discovered and proved the metamorphic rock is a set of oceanic volcano-spout deposit rock in Lao Junshan minerogenic region.On the basis of research about ore deposit geology and mineralization rule for Lao Junshan minerogenic region, divided the ore deposit in Lao Junshan minerogenic region into three metallogenic series and ten kinds of the deposit type.2. Using the geological rule and the thing, melts the digital space information and computer and the software integrated technology, each kind of mineralization information obtains which to each research stage conducts the synthetic study and the organic integration, On this foundation main utilization unit standard allocation method, Uses the improvement two condition valuations to carry on the evaluation to Lao Junshan region each variable,And carries on the attribute computation using the GIS software, Completes the Laojun minerogenic region synthesis information model through these steps the establishment, And carries on the synthesis information mineralization forecast in this foundation. Finally obtained the entire mining area synthesis score.3. On the foundation of synthesis score, introduced the analytic hierarchy process to compute the weight value first time, Then utilization the quantitative evaluation mathematical model of geologic anomaly prospecting target area, to the mineralization advantageous land sector which iriss out has carried on screening and the rank division, Carries on the division by using the prospecting probability. We separately Man Jiazhai and Nan Yangtian as the reference ore deposit, After computed,we got oneâ… level target,fourâ…¡level target and sixâ…¢level target. 4. Has established the digital ore deposit model in Man Jiazhai ore section first time, and has realized the ore deposit each useful information digitization and the visualization. Has established the ore deposit theory variation function model through variation function computation and simulation. Initially discussed the ore body shape spatial variation characteristic and the influence factor.5. Summarized the mineralization rule of ore body, Through ore deposit model, separately the trend, tendency and vertical of ore body, has calculated the zinc,tin personal status and the tonnage in the different boundary according to certain length of stride, and utilized other computer software to manufacture the zinc,tin personal status and the tonnage change chart at three direction.Has summarized mineralization rule of the ore body by mathematics and the graph, changes traditional the qualitative analysis for the quantitative analysis.6.0n the basis of the digitized deposit, through the analysis of the mineralizing isoline in Man Jiazhai, we carried out the research of the trend of Skarns%theF0,the F1 break seeks Sn,Zn ore body in the border and depth of the deposit, not only is one brand-new exploration of the geological statistics theory and the digitized deposit in metallogenic prognosis aspect, also provided the clue for the prospecting in the mine depth.
