Lunar Olivine EPMA Maps and Spot Analyses for Nanoparticle Study

EPMA and TEM-EDS data support the study 'Metallic nanoparticles in a lunar olivine rim reveal impact-induced subsolidus decomposition'. The dataset contains two types of analytical data: EPMA maps of a studied olivine rim and EPMA spot analyses of a specific olivine grain. It is stored in XLSX and TIF formats.

Use Cases

• Analyzing elemental distribution across a lunar olivine rim using EPMA maps
• Comparing specific spot compositions within the olivine grain from EPMA spot analyses
• Investigating the relationship between impact events and subsolidus decomposition
• Correlating nanoscale metallic nanoparticle occurrences with bulk mineral chemistry

Strengths

• Data is directly linked to a specific, named scientific study, providing clear context
• Contains two distinct, complementary data types: spatial maps and discrete spot analyses
• Available under a permissive CC-BY-4.0 license for reuse
• Cross-platform presence on figshare indicates established sharing and importance

Limitations

• Column names and row counts are not provided, limiting immediate understanding of data structure
• The dataset size (40097430) is given without units, making its scale ambiguous
• No organizational affiliation for the author is listed, reducing institutional context
