Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of universal technical methods to determine the occurrence of a concealed plate-shaped ore body of a hydrothermal deposit, particularly in terms of its strike, dip direction, dip angle, and pitch direction, due to limitations in existing prospecting methods and spatial extension, leading to deviations in inferred positions.
Innovation Solution
A method involving fine measurement of metallogenic structures, systematic sample collection, multi-element quantitative analysis, and construction of a mathematical model based on characteristic element combination anomalies to derive the occurrence of deep concealed ore bodies, using first-order derivative functions to determine the strike, dip direction, and pitch direction.

1Productivity
If three-dimensional model and analytical geometry method are used for location prediction, then the prediction can be made based on existing data, but the inferred ore body occurrence position often deviates from the actual ore body position due to limitation of prospecting engineering and spatial extension
Solution Approach 1:
The patent transforms the prediction approach by changing from direct spatial modeling to derivative analysis of geochemical anomaly distributions. It uses first-order derivative functions to characterize the spatial variation of characteristic element combination anomalies, which reveals the occurrence parameters (strike, dip direction, dip angle, pitch direction) of concealed ore bodies more accurately than traditional three-dimensional modeling methods.
Solution Approach 2:
The patent replaces the mechanical/geometric modeling approach with a mathematical field theory approach. Instead of using analytical geometry methods that rely on assumed ore body shapes and positions, it employs derivative analysis of geochemical anomaly fields to indirectly determine ore body occurrence, thereby avoiding the limitations of direct spatial extrapolation.
2Adaptability or versatility
If geochemical primary halo or secondary halo anomalies are used to determine deep concealed ore body occurrence, then the method can be applied universally to different deposit types, but there is currently no universal technical method to determine the occurrence (strike, dip direction, dip angle, pitch direction) of concealed plate-shaped ore bodies
Solution Approach 1:
The patent creates a universal methodology that can determine the occurrence parameters of concealed plate-shaped ore bodies across different deposit types. The method uses characteristic element combination anomalies and their first-order derivatives, which can be applied to various hydrothermal deposits regardless of specific geological conditions, making it universally applicable while maintaining high precision.
Solution Approach 2:
The patent transitions from analyzing two-dimensional anomaly distributions to utilizing three-dimensional derivative characteristics. By computing first-order derivatives in multiple spatial directions and analyzing their distribution patterns, the method extracts occurrence parameters (strike, dip direction, dip angle, pitch direction) that represent the three-dimensional orientation of concealed ore bodies, thereby solving the precision problem through dimensional transformation.

AI summary
Provided is a characteristic element combination anomaly derivative method of determining occurrence of a deep concealed plate-shaped ore body of a hydrothermal deposit. The method determines the spatial occurrence of the deep concealed ore body of the hydrothermal deposit through four working procedures, including: fine measurement of a metallogenic structure and systematic collection of samples, sample processing and multi-element quantitative analysis, mathematical model construction of characteristic element combination anomaly, and determination of the occurrence (the strike, the dip direction, the dip angle and the pitch direction) of the deep concealed ore body. The method solves the problem of judging the occurrence of the deep concealed ore body by interpreting geochemical anomalies of a primary halo and a secondary halo.
