Engineering Contradiction Analysis
1Reliability
If conventional exploration methods (large-scale geological mapping, geophysical and geochemical exploration) are used to evaluate metallogenic potential, then evaluation reliability is improved, but exploration time and cost increase significantly
Solution Approach 1:
The patent extracts the key diagnostic information from the complex exploration process by focusing solely on magnetite trace element composition (Ti, Ni, V, K, Al+Si+Mg). This extraction allows rapid evaluation without requiring comprehensive geological mapping, geophysical surveys, or extensive drilling, thus reducing time while maintaining evaluation reliability through chemically controlled discrimination factors.
Solution Approach 2:
The patent changes the evaluation parameters from traditional geological mapping and multi-method exploration to specific chemical composition parameters of magnetite. By using trace element ratios and calculated discriminant factors (F1-F4) based on magnetite chemistry, the method achieves rapid classification of metallogenic potential while reducing exploration time and cost.
2Measurement precision
If conventional exploration methods are used to evaluate metallogenic potential, then evaluation accuracy is improved, but exploration cost increases significantly
Solution Approach 1:
The patent extracts only the essential chemical composition data of magnetite (trace elements Ti, Ni, V, K, Al+Si+Mg) for evaluation, eliminating the need for expensive comprehensive geological mapping, geophysical surveys, and extensive drilling. This extraction maintains evaluation accuracy through chemically controlled discrimination while significantly reducing exploration cost.
Solution Approach 2:
The patent uses inexpensive trace element analysis of magnetite as a disposable screening tool to rapidly assess metallogenic potential. Instead of investing in expensive conventional exploration methods, the method employs affordable chemical analysis to make initial evaluations, reserving drilling and detailed exploration only for high-potential areas.
3Adaptability or versatility
If conventional exploration methods are used to evaluate metallogenic potential, then evaluation comprehensiveness is improved, but exploration efficiency decreases
Solution Approach 1:
The patent creates a universal evaluation system based on magnetite trace element composition that can be applied to all skarn deposits regardless of size, location, or specific geological characteristics. The discriminant factor calculations (F1-F4) provide a multi-functional assessment framework that simultaneously evaluates multiple aspects of metallogenic potential through a single chemical analysis approach, greatly improving exploration efficiency.

AI summary
The present invention discloses a method for evaluating a metallogenic potential of a skarn deposit based on the magnetite composition, including collecting geological, geophysical, geochemical, and remote sensing data in a studying area, systematically, and delineating a favorable area for mineralization; collecting magnetite-bearing samples in the favorable area for mineralization, and describing the lithology, alteration and mineralization characteristics of each sample; selecting the most representative magnetite samples for chemical analysis to obtain average contents of trace elements Ti, Ni, V, K and Al+Si+Mg, denoted as c(Ti), c(Ni), c(V), c(K), and c(Al+Si+Mg) in ppm; and calculating discriminant factors F1, F2, F3, and F4 by substituting data, and performing discrimination; and when the four discriminant factors all discriminate the metallogenic potential to be better, determining the skarn deposit in the favorable area for mineralization to have a good metallogenic potential; and discriminating as a poor metallogenic potential in the remaining cases.
