Tutorial: Create a Multi-Panel Lithology Cross-Section

Estimated time: 5 minutes.

In this lesson, you will create a multi-paneled set of section panels using the same lithology model you created in the previous lesson. The instructions below are written with the assumption that you have completed that lesson, as well as the lesson on log sections. You'll be using the same settings for the lithology cross section.

1. Click on the Lithology Menu and choose Section.
   
2. Main Options: These settings will set up the model and diagram settings. These are found in the left pane of the Lithology Section window.
   • Vertical Exaggeration: This should be set to 1. In your own work, if your project area is large but your logs are shallow, this is a means of setting a vertical stretch for the section, before it's created, so that the border annotation is scaled well.
   • 
     
   • Model: Establish the model settings.
     • Use Existing Model: Click in this button to tell the program you want to use the same, existing lithology model file.
     • Solid Model: Click here to select the file named Lithology.RwMod, created in the previous lesson.
     • 
       
   • Fill Options: Click here to define how the section panels are to be displayed.
     • Fill Background: Check this box to be sure that the background colors for the rock types are displayed in the section.
     • Fill Patterns: Check this box to display the pattern designs as well.
     • 
       
   • Confirm the following settings are still established, from the log section lesson:
     • Striplogs: RockWorks will append 2D logs to the section panels.
     • Annotation: The defaults from the earlier lesson should work.
     • or Surface Profile: This option can be either checked or not, as per the log section lesson.
     • Faults - Other 2D Files: These should be off.
     • Peripherals, Pattern Key, Lithology: This should still be activated.
     • 
       
3. Check the striplog options: These should still be set up as they were for the log section; if you want to review the 2D log settings you can click on the 2D Log Design tab at the top of the window.
   

   

4. Check the selected boreholes: These should also still be set up as they were for the log section. To verify the placement of the section trace, click on the Section Location tab at the top of the window.

   

5. Location Map: This should still be checked as it was for the log section lesson. To verify the settings, click on the Location Map tab at the top of the window.

   

6. When you're ready to proceed, click the Continue button at the bottom of the window.

   The program will read the existing solid model (lithology.RwMod) and extract panels along the indicated cross-section trace. It will build them into a continuous cross section diagram, with the indicated perimeter annotation and surface profile line. The lithology logs will be appended to the section diagram. The completed diagram will be displayed in a RockPlot2D tab in the options window.

7. Save the diagram: Choose File | Save and save this diagram under the name:    Lith Panel Section    and click Save.
   
8. Resize the lithology legend:
   1. Click on the Edit arrow in the upper-left corner.
   2. Click on the lithology legend to the right of the section, to select it.
   3. Position the cursor on the lower-right corner of the legend rectangle, on the handle; you'll see the cursor shape change to
   4. Click on that handle, hold down the mouse, and drag slightly to the right. The legend will be rescaled in the new rectangular space.
   5. If you want to view some of the legend options, you can double-click on the Lithology Legend.
   6. Click OK to close the Legend Attributes window.
      
9. Layers: 
   1. Find the Layers pane in the RockPlot2D window in the upper-right. (If it is hidden, you can display this pane by clicking on the small + button in the upper-right corner.)

      

   2. Use the check-boxes displayed there to turn on/off some of the different components of the diagram, such as different rock types or annotations.
   3. If you want to fill the plot window with the diagram, click the Stretch button. If you ever want to get back to the original 1:1 scale of the section, click the VE: button at the top of the window, and enter: 1.
      
10. Save the changes you've made: click the button.
    
11. Close the Lithology Section window.
