Geochemical Features And Metallogenic Prognosis In Jinhong Area Huize Yunnan Province

Since the Program of Superseding Resources exploration for the national Crisis Mines in2004, the depth and the periphery exploration of the large and medium-sized mines has achieved significant results. The study area is located in the Zhehai、 Kuangshanchang village which town of Huize, is located in the south of Kuangshanchang-jinniuchang structure belt. Northern part of the study area of about12km at the for Huize very large lead-zinc deposits.Known mines peripheral advantage prospecting conditions, easy to find minerals.This place has excellent forming geological conditions, and significant exploration potential.Study belonged to the survey blank area and a good place. Do prospecting research of great significance.Paper on the basis of the results of previous studies.By detailed field geological and geochemical data analysis and testing.Participants Chak lead and zinc do a comparative study.Ore-bearing stratigraphic and lithologic characteristics, structural characteristics, REE characteristics of in-depth study.Summarizes the metallogenic conditions.Combination of rock geochemistry, tectonic geochemical anomaly characteristics and metallogenic prediction.Made the following conclusions and results:(1) Summary and study the tectonic background of the study area, the regional geological and geochemical characteristics; summary and study geological features of the Huize Pb-Zn mineral composition of the ore and wall rock alteration characteristics; by detailed geological work and interiorsummarizes the geological setting and geological characteristics of the study area.(2) The study area participants Ze lead-zinc placed Junior Group dolomite.REE spider diagram mode curve overall pattern consistent with enrichment in LREE-HREE ratios flat type. Eu are negative anomalies. Research District,, Eu negative anomaly, rich in light rare earth is flat. Huize Pb-Zn mining factory fault zone, Eu positive anomaly, than the rich in light rare earth elements, changes in the heavy rare earth is flat.(3) Rock geochemical survey on the basis of detailed geological work in the study area. Removed using iterative high-value method to determine the background value and abnormal lower limit.Element of the rock geochemical analysis.The unusual combination of elements, the abnormal concentration Center, abnormal strength, the abnormal area, abnormal continuity statistics.Delineated eight exceptions, in the areas of Chejiaping Fujialiangzi sub-regions delineated four integrated anomaly.(4) Summed up the basic theory and methods of work of the tectonic geochemistry, tectonic geochemical survey of the major faults of the study area, to strengthen the rock geochemical anomalies, provide the basis for the delineation of rock geochemical abnormal, indicating that the ore-forming fluid flow.(5) On the basis of concluded the ore-forming geological conditions, combined with thecharacteristics of geophysical and geochemical exploration. After ore-forming prediction,we pointed out1Ⅰ-type exploration targets,2Ⅱ-type exploration targets in Chejiaping,and pointed out2Ⅰ-type exploration targets,1Ⅱ-type exploration targets in Fujialiangzi.
