Unconformities and geological histories: conformable and unconformable contacts
Summary
This workflow uses Visible Geology to understand the differences between conformable and unconformable contacts and types of unconformities. Students will also use unconformities to interpret basic geological histories of a region.
CollapseLearning Goals
Learning objectives:
- Distinguish unconformities from conformable contacts
- Identify different types of unconformities
- Interpret the full geological history of an area using conformable and unconformable contacts within a sequence
Key Visible Geology skills:
- Apply unconformities to a model
- Apply dikes to a model
- Use the History tab to edit geological histories
Context for Use
This ~1 hour workflow is a standalone tool for students to either work through as part of a guided lab exercise that builds on lecture material, or as an independent exercise to consolidate learning. It builds concepts from the ground up so it is appropriate for high school to junior college level students.
Description and Teaching Materials
Visible Geology needs to be available for each student, along with the attached worksheet .pdf. Students work through the worksheet, following instructions and exploring the model as it is developed. Key learnings are highlighted in the worksheet at every step. Questions towards the end of the worksheet interrogate students' understanding, before an exercise getting them to apply their new knowledge finishes the worksheet.

Assessment
If students are able to answer the questions and complete the final exercise adequately, then they have met the learning objectives of this workflow.
