Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for denudation depth mapping are limited to small-scale, irregular, and non-normative thermochronology maps, lacking standardized geological base maps, which hinders comprehensive evaluation of mineral deposit preservation and change, and large-scale mapping is urgently needed for regional geological evolution research and mineral exploration.
Innovation Solution
A large-scale denudation depth thematic mapping method involving field work point and route arrangement, sampling rules, field observation and recording, mineral processing, and data analysis using improved Low-T Thermo software to create accurate denudation depth maps on standardized geological base maps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If small-scale, irregular thermochronology maps are used, then field operation is relatively easy, but comprehensive evaluation of mineral deposit preservation and change cannot be achieved
Solution Approach 1:
The patent divides the large-scale mapping area into multiple survey regions with standardized sampling grids and work points. Each region is segmented into manageable units that can be surveyed independently using uniform methods, allowing comprehensive coverage while maintaining operational feasibility through modular field work organization
Solution Approach 2:
The patent establishes a universal standardized methodology that can be applied across different regions and scales. The same sampling rules, work point arrangements, and data processing procedures are used throughout the entire survey area, enabling the system to handle both detailed local studies and comprehensive regional evaluations with a single unified approach
2Loss of information
If large-scale denudation depth mapping is implemented, then comprehensive evaluation of mineral deposit preservation and change can be achieved, but mapping complexity and data processing difficulty increase
Solution Approach 1:
The patent performs preliminary standardization of sampling rules, work point arrangements, and data collection protocols before conducting the actual large-scale survey. By establishing uniform methodologies in advance, the complex task of large-scale mapping is broken down into standardized preliminary procedures that simplify subsequent data processing and analysis
Solution Approach 2:
The patent transforms complex geological data into standardized parameters through systematic processing. By converting diverse field measurements into uniform denudation depth values using consistent calculation methods and software procedures, the patent reduces data complexity while preserving comprehensive evaluation capabilities
