About Stonefieldlane
Stonefieldlane is a field reference covering glacial erratic stone identification, Quaternary geology context, and the practical and historical uses of fieldstone in Polish agriculture.
The content on this site is aimed at farmers, landowners, amateur geologists, and anyone who encounters large or unusual stones in cultivated fields in northern and central Poland and wants to understand what they are looking at. Articles cover the visual characteristics of common erratic rock types, the mechanisms of glacial transport, and the traditional practices surrounding stone clearance and use.
Scope
Coverage focuses on:
- Glacial erratics deposited by Quaternary ice sheets in Poland — primarily the Vistulian (Weichselian) glaciation
- Rock type identification using field-observable characteristics (no laboratory equipment required)
- Distribution of erratic types across Polish administrative regions
- Traditional agricultural and architectural uses of field stone
- Ecological role of stone rows and clearance piles in the agricultural landscape
This site does not cover industrial stone quarrying, precious minerals, or meteorite identification.

Content draws on publicly available geological survey data and publications including:

Disclaimer
Field identification of rock types without laboratory analysis carries uncertainty. The guidance on this site is intended as an orientation aid, not a definitive classification. If precise petrographic identification is required — for example for construction material assessment — professional geological analysis is recommended.
