Fault Tables

This table is used by most of the gridding algorithms if 2D Faulting is selected in the Gridding Options window.  The faults will be stored in the grid model and can be represented in contour maps (Fault Polylines activated).  You can also create stand-alone fault polyline maps.

A Fault Table lists the X1,Y1 and X2,Y2 endpoints for the line segment(s) making up the fault trace(s).  During gridding, these fault line(s) create a barrier between grid nodes on one side and control points on the other side of the line, so that these points have no influence on the computation of the node values. 

! You can store multiple Fault tables in your project database.  If you assign detailed names they'll be easy to distinguish when you're selecting which to use. Fault tables can be accessed in the Project Manger, under the Project Tables | Map/Model Tables grouping.  

Table Format

• Order: The first column simply lists the order of the coordinate pairs and, hence, the sequence of the line segments.  This can be any real number value, though you'll probably number your rows "1", "2", "3", etc. 
• X1 (Easting), Y1 (Northing): These columns list the X and Y coordinates for the starting endpoint of the fault line segment. 
• X2 (Easting), Y2 (Northing): These columns list the X and Y coordinates for the ending point of the fault line segment. 

! If you need to determine the real world coordinates for the fault line(s), create an unfaulted contour map or a simple point map first, use RockPlot2D’s Draw | Polyline or Draw | Line tools to draw the fault polyline(s), then right-click on the lines to save them to a Fault Table.  See Defining Fault Lines for an example.

Your Fault Table might contain a single row only, representing a single line segment.  Or, it might contain many rows representing multiple segments that are connected to each other or not.
