绿泥石短波红外光谱特征在地质找矿中的应用OA

In the 21st century,with the gradual depletion of global surface mineral resources,the current mineral exploration is moving towards the"deep exploration"and"hidden ore body detection",the use of short-wave infrared spectroscopy to study the spectral characteristics of different deposits of chlorite minerals to guide The use of short-wave infrared spectroscopy to study the spectral characteristics of chlorite minerals in different deposits can guide the exploration of deep and hidden minerals.This paper systematically summarizes the application and development of short-wave infrared spectroscopy of chlorite minerals in sillimanite-type deposits,porphyry-type deposits,shallow-forming low-temperature hydrothermal deposits,volcanogenic massive sulfide(VMS)deposits,and orogenic gold deposits by reviewing the relevant literature of the predecessors.Based on the characteristic parameters of chlorite short-wave infrared spectra,the hydrothermal centers of mineralization and mineralization potential zones can be quickly defined.The absorption depth data of chlorite characteristic absorption peaks are obtained by using TSG software.The method is simple and easy to use,with simple work and short analysis time,which can realize the relationship between alteration minerals and mineralization in the field quickly,and greatly shorten the work cycle and improve the efficiency of ore searching compared with the traditional method.It solves the problems of traditional geological mineral searching methods,such as alteration minerals are not easy to distinguish and identify by naked eyes,and laboratory tests are costly,time-consuming and inefficient.
