Editorial interest 82/100 Selection signal · not a rating of the site

A set of interactive geology lab tools for identifying minerals, reading stereonets, solving structural geology problems, and practicing with worked solutions.

Landing page captured for the 2026-10-20 issue.

For: Geology students practicing lab identification and structural problems
Worth noticing: Set codes rebuild the same problems and answer key, and can also be used to grade bubble sheets.

Field notes

The stereonet accepts strike/dip, dip-direction/dip, trend/plunge, or pasted measurements, and distinguishes the equal-area Schmidt net from the equal-angle Wulff net. Practice sets cover topics from Mohr circles to thin-section minerals; the page says a set code reproduces the same questions and key, with bubble-sheet grading also available.
