ROCK CORE VALIDATION EXAMPLE

WinLoG Rock Core QA/QC Example

Focused validation of rock-core logging, recovery, quality and engineering data.

This example shows how WinLoG can combine detailed rock descriptions with core-run measurements and automated QA/QC. BH-03 CORE-QAQC presents a 30 m rock-core borehole with RQD, Solid Core Recovery (SCR), Total Core Recovery (TCR), weathering, rock hardness, fracture spacing, compressive strength, groundwater observations, and validation findings in a single two-page log.

The example intentionally contains selected data-quality conditions so users can see how WinLoG identifies physically inconsistent core-recovery relationships, interval geometry problems, and unusual geological conditions while preserving the underlying log for engineering and geological review.

How the Example Demonstrates Rock Core QA/QC

BH-03 is intentionally not a perfect borehole. The validation report identifies 2 errors and 2 warnings. The errors include overlapping lithology intervals and an SCR value that exceeds TCR. The warnings identify an RQD value greater than SCR and bedrock encountered at an unusually shallow depth.

The example therefore demonstrates both objective data-integrity failures that require correction and unusual geological conditions that require review. The completed log has 100% completeness, a 63% confidence score, and a validation status of Failed until the outstanding errors are addressed.

Example Findings

Selected Rock Core QA/QC Conditions Demonstrated

Validation Errors

Intervals must not overlap: the example includes an intentionally overlapping lithology interval so WinLoG can demonstrate interval-geometry validation.
SCR cannot exceed TCR: at the affected core run, SCR is 94% while TCR is 89%, creating a physically inconsistent recovery relationship.

Validation Warnings

RQD greater than SCR: the example contains RQD of 76% and SCR of 70%, flagging the core-quality relationship for review.
Bedrock encountered unusually shallow: rock begins at the surface in the demonstration borehole, producing a review warning rather than an automatic correction.

Core Recovery Relationships

The RQD, SCR, and TCR columns make related core-quality measurements visible side by side. This layout helps reviewers quickly compare values within each run and identify relationships that are physically impossible or worthy of further review.

Geological & Engineering Context

Weathering, hardness, fracture spacing, and compressive strength are plotted alongside recovery data so the reviewer can evaluate QA/QC findings in geological context rather than considering each measurement in isolation.

Applications

Who This Example Is For

Geotechnical Consultants

Demonstrates structured rock-core logging for foundation, tunnel, dam, transportation, and other engineering investigations where recovery and rock-mass quality must be reviewed.

Mining & Exploration Teams

Shows how geological core descriptions, RQD and recovery data can be stored and validated consistently before they are used for interpretation, modelling, or resource work.

QA/QC Reviewers

Illustrates how interval errors, recovery inconsistencies, and unusual geological conditions can be surfaced before a borehole record is reviewed, approved, or issued.
