About this layer

Rock samples show laboratory results from pieces of rock collected for testing. Compare neighbouring samples to see whether an interesting result follows a rock unit or a vein. One rich sample may not represent the surrounding ground.

What it is for

Compare nearby samples and the mapped rock units. Open the record, where available, to check the sample description.

Limits

A selected rock sample may not represent the surrounding ground. Check units before comparing it with soil or stream readings.
