Method and system for determining mineralization mechanism of sedimentary metamorphic iron ore

The invention relates to the technical field of mineral exploration, in particular to a method and system for determining a sedimentary metamorphic iron ore mineralization mechanism, and the method comprises the following steps: calculating correlation among multiple variables and extracting key factors based on sedimentary metamorphic iron ore data by adopting factor analysis and correlation mapping technologies; hidden metallogenic factors in the data are identified through factor analysis, the interaction among the metallogenic factors is explored through canonical correlation analysis, the common influence of the metallogenic factors on the metallogenic process is analyzed, and a metallogenic key factor mapping is generated. According to the method, the comprehensive efficiency and accuracy of the multi-source geological data are improved through combined constraint reverse modeling, so that comprehensive interpretation of a mineralization mechanism is deeper, the microscopic geological process can be fin
