Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no systematic method for delineating exploration reserved areas of deep-sea polymetallic sulfide resources, which hinders the progress of exploration and resource evaluation.
Innovation Solution
A method involving the extraction and grading of prospecting indicators such as plume, geophysical, geochemical, biological, and mineralized outcrop information to delineate exploration reserved areas, where specific characteristics and grades of these indicators are used to determine the scope and potential of prospect areas, ultimately guiding the delineation of reserved areas.

1Productivity
If no systematic method is used for delineating exploration reserved areas, then exploration progress is restricted, but formulating an appropriate exploration delineation strategy requires complex analysis of multiple prospecting indicators
Solution Approach 1:
The prospecting indicators are segmented into six distinct categories (plume information, geophysical information, geochemical information, biological information, wall rock alteration information, and mineralized outcrop information), each with specific characteristics and grades. This segmentation allows systematic evaluation of different types of data independently while maintaining overall exploration progress
Solution Approach 2:
The method changes parameters by assigning specific grades to different types of prospecting indicators based on their credibility and significance. By establishing graded parameters for each indicator type, the method transforms complex qualitative data into quantifiable evaluation criteria that can be systematically applied
2Measurement precision
If multiple types of prospecting indicators are analyzed to determine prospect area grades, then the accuracy of exploration reserved area delineation is improved, but the time and resources required for analysis increase
Solution Approach 1:
The method performs preliminary action by pre-defining the characteristics and grades of all six types of prospecting indicators before actual evaluation. By establishing the evaluation framework in advance with specific criteria for each indicator type, the actual fieldwork and analysis can proceed more efficiently without ad-hoc decision-making
Solution Approach 2:
The evaluation method serves multiple functions simultaneously: it evaluates different types of prospecting data, determines prospect area grades, identifies exploration reserved areas, and provides a systematic framework for resource assessment. This multi-functionality reduces the need for separate analysis procedures for each indicator type
