Mineral Prediction Of Gold Deposits In Huma Area Of Heilongjiang Province

Huma Area of Heilongjiang is located in the northwestern region of Heilongjiang Province. It belongs to Da Xing’an Mountain region, including Huma County, the parts of Heihe City, Xinlin and Jiagedaqi. Huma region is one of the important producing areas in Heilongjiang Province with gold, copper, lead, zinc and other mineral resources. In Huma Area, gold prospecting has made a breakthrough, and people also found a number of gold deposits (mineralized spots), and found a large number of gold mineral natural heavy concentration anomalies and hydrographic deposits Au anomaly, which show that the region has a strong potential for mineralization.The task of this research is to carry out the gold resources prediction research based on the early geological survey in Huma area, the mineral exploration and research work, and the mineral resources prediction methods which use comprehensive information The research results will serve as a reference basis for the deployment and decision of the research in the area of rock gold ore prospecting.The main aspect of the research is, we collect comprehensive Huma regional geology, mineral materials and summarize the research status of development; conduct a comprehensive interpretation of geology, physics, chemistry, remote sensing data and capture useful information about various subjects; analysis summarizes metallogenic features rock gold deposits, mineralization control conditions and metallogenic regularity; identifying relationship between information; build prospecting Model rock gold deposits; development of gold resources prediction, Including unit division, variable study, location prediction mathematical model prediction, work proposal and other systems work.This study achieved the following results:1. According to the conditions of geological ,regional metallogenic environments and metallogenic, we made the system and conclude systematically. We analyze the study area including different map sheet (1:250000), and integrate the data of geology, physics, chemistry, forming a unified scale coverage of the study area, geology, physics, chemistry, of the more comprehensive information system, and create the conditions to carry out work on predicting areas.2. Coverage of the study area for gravity and magnetic measurement results and the results of data processing is to integrate geological interpretation prior premise. The study area is to identify areas of gravity and magnetic characteristics, divided heavy, magnetic field, the delineation of the regional anomaly, gravity and magnetic extract useful information for the study area was inferred fault system. Severely magnetic angles deepen the understanding of the study area faults, the first east-west, north-east, the second north-west, north to south.3. According to the study of Pangkaimen gold, Sidaogou gold typical ore deposit, geological environment, we summarize the metallogenic characteristics of gold deposits in the study area; comprehensive study area known gold deposits (points), Gold mineralization analysis of mineralization controlled conditions summarized metallogenic regularity;magmatic hydrothermal gold deposits and build predictive models of the Pangkaimen gold which is represented. Magmatic hydrothermal type gold deposit is established in the Pangkaimen gold as the representative of the predictive model.4. Preparing for the catchpits’s network diagram, and using geological unit division method of geological units. We identified 20 mineralizations which is called upon to unite, the preparation for the map of the distribution of gold resources of Huma region.5. Research on geology, physics, chemistry related information relationships, using characteristics analysis method to design a mathematical model of gold position evaluation, and we completed a gold mine location estimation. Huma gets mineralization possibilities of Heilongjiang Province larger prediction unit 14 Class Ⅰ, Ⅱ level prediction unit 4, Ⅲ-level prediction unit 2.6. On the basis of the above researches, we draw up a deployment diagram and propose Huma area exploration in Heilongjiang Province; we proposed 2 zones, respectively:Sidaogou area and Pangkaimen prospect area, which can be a reference for the future gold prospecting.
