Rough surfaces known as stylolites are common geological features that developed by pressure solution, especially in carbonate rocks, where they used strain markers and stress gauges. As applications developing various settings, questions arise regarding the uncertainties associated with quantitative estimates of paleostress using stylolite roughness.
