Rock Physical Properties of Japan with 7,274 Samples

7274 rock samples from Japan have their physical properties recorded in a standardized database. The dataset, created by SCIOPS and last updated in March 1988, includes nine key properties such as density, porosity, thermal conductivity, magnetic susceptibility, and P-wave velocity. It is intended to provide basic data for geophysical prospecting.

Use Cases

• Model subsurface structures for geophysical prospecting based on P-wave velocity and density data.
• Analyze rock composition and integrity for engineering geology based on porosity and density measurements.
• Study paleomagnetic fields and rock magnetism based on natural remanent magnetization (NRM) intensity, declination, and inclination.
• Calculate thermal properties for geothermal or crustal studies based on thermal conductivity data.
• Classify rock types and assess their physical characteristics based on the combined nine property measurements.

Strengths

• Contains measurements for 7,274 distinct rock samples.
• Records nine standardized physical properties per sample, including density, porosity, and magnetic susceptibility.
• Some properties like density and P-wave velocity are subdivided into natural, dry, and wet conditions.

Limitations

• Last updated 1988-03-30 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is known, but sample provenance, collection methods, and specific locations are not detailed in the provided metadata.
