[Research on Assessment Methods of Spectrum Data Quality of Core Scan]

Area of Science:

• Geoscience and Spectroscopy
• Instrument Development for Earth Sciences

Context:

• Core scanning instruments digitize geological core samples for analysis.
• Accurate core data is vital for mineral identification, deposit studies, and resource prospecting.
• Existing methods lack standardized data quality assessment criteria.

Purpose:

• To develop and validate a comprehensive data quality assessment method for core scanning instruments.
• To evaluate the reliability and validity of the independently developed CSD350A core scanner.
• To provide a foundation for quality assurance in commercial core spectrum testing services.

Summary:

• The study details the development of the CSD350A core scanner and its associated data quality assessment methodology.
• Key assessment parameters include reflectance spectrum, wavelength accuracy, repeatability, and signal-to-noise ratio.
• Experimental validation confirms the instrument's reliability and the effectiveness of the proposed assessment methods.

Impact:

• Establishes crucial criteria for evaluating core scan data quality in the absence of industry standards.
• Enhances the reliability of geological research, mineral exploration, and resource management through accurate data.
• Facilitates the creation of online core databases, improving resource accessibility and reducing preservation costs.
