Comprehensive Information Of Minefor Antuoling Porphyry-type Molybdenum Deposit In Hebei Province

Remote sensing technology has the capacity of reflecting the earth’s surface information macroscopically and instantaneously with the different platform; the different wave band; the different resolution; the different phases; the multiple-perspectives; omni-directional and multi-attribute. Along with remote sensing technique’s fast development, the combination way of Remote sensing technology and the conventional geology, the geophysics, the geochemistry has become the mainstream of modern prospecting technology.This article is processed under the "Antuo Range Magmatic activity And Mineralization" project, with the aid of the remote sensing and the GIS computing technique, extracted the alteration information and processed the structural information extraction interpretation in the development research area, simultaneously unifies the geology, geophysical prospecting and chemical prospecting data, analyzed the Antuo range molybdenum ore magmatic activity and the mineralization relations, summarized the porphyry copper molybdenum ore deposit mineralization rule and the prospecting symbol, and carried on the Metallogenic forecast. Following conclusions are obtained through experiment and research:1) It’s found that surface’s alteraton has zoning character and radial pattern in the process of preparing Antuo Range 1:2000 geological map, alteration zone distributed likes scallops. According the constructed drill material, the whole alteration zone could be divided into Potassic- silicification zone; propylite zone and silicification /pyritization zone from bottom to top.2) Established the interpretation symbol of the linear structure and ring structure. Through remote sensing phantom digital image processing and the application of visual interpretation, extracted the linear structure information of research area. According the tectonic location, he faults include NE, NNE and NW. Nearly east-west and. The research area Through the remote sensing interpretation to the research area, discovered that the faulted structure presents the characteristic of disorderly distribution in the mining area, and confirmed the principal stress is upward vertically, it also distinguished the Ring structures has the features of large ring setting of small ring.3) Through the radiometric correction and removing of various interference factors in the study area, are hydroxyl and iron dye abnormal extraction.For the extraction of altered information, ore-controlling structures in space and the known deposits related point analyze the relationship, and the results show that the altered information extraction method is feasible in the Antuo Range area, most of the altered information are related with altered. Altered information distribution along with regularity, most ore potentiality in banded form distribution; tectonic Altered information coincided with known mineralization point perfectly.4) The using of EH4 in the exploration of molybdenum, the core of data and hydrochemical anomaly data mining was carried out to verify that this paper studies the structure, and became the first to use of information extraction, and then on, and geological exploration hydrochemical anomaly hardly find the method is workable.5) Structure use of information extraction is to change the method of research areas to find the forecast, and specifically to a target area.
