Cross-sections are used to depict the vertical structure and stratigraphy of the subsurface. Typically cross-sections intersect several boreholes that may or may not be along a straight line. The stratigraphic information from the boreholes is combined with other knowledge of the area to generate the cross-section.
WinFence can be used to graphically create detailed, full-color, cross-sections and fence diagrams quickly and easily. The program can be used to interpret and map soil and rock layers, contamination, fossils, minerals and hydrocarbons.
A wide variety of strata can be used to create cross-sections in WinFence. Types of strata that can be used include layers, faults, lenses, intrusions, and alteration zones. Very detailed and complicated stratigraphy can be represented and easily drawn. Layers can contain multiple segments to represent uncomformities and erosion in highly faulted zones.
Before using the WinFence program it is recommended that the tutorial in this chapter be completed. This tutorial will give you a basic understanding of how to use the WinFence program. It describes how to select a project, enter the cross-section data, and print the cross-section.
It is recommended that while you read this tutorial you perform the actual procedures discussed using the WinFence program. The program includes the “WinFence Tutorial” project and template that are referred to in this chapter.
This tutorial describes how to:
1. Select a project
2. Create a new cross-section
3. Enter the title bar data
4. Edit the strata
5. Save the cross-section
6. Print the cross-section
7. Display the Fence Diagram
Each of these steps is discussed in detail below.
