Symbol Log Data

Previous pageReturn to chapter overviewNext page

Symbol logs are used to represent lithologic samples that do not necessarily correspond with any lithologic layers. The lithologic symbols shown are independent of those specified in the lithology. Unlike core logs, there can be any number of symbol log columns.

 

There are several ways to edit symbol log data, either:

 

click on the symbol log column on the log

double click on the symbol log object on the sidebar

select Edit > Symbol Log

or select Popup > Symbol Log

 

After this the Symbol Log form will be displayed. At the bottom of this form there are buttons to move to the first, previous, next, and last symbol or to add and delete symbols.

(The appearance of the form will differ slightly depending on if it is WinLoG or WinLoG RT)

 

The following information can be entered and edited using this form:

 

Top Depth: This is the top depth of the symbol.

 

Bottom Depth: The bottom depth of the symbol.

 

Library: This is used to select the symbol library for the symbol. When the arrow at the right is pressed a list will display the available symbol libraries. After a library has been selected, the symbols displayed will be updated.

 

Symbol: The symbol can be selected by clicking on one of the 18 symbols displayed for the current library. The selected symbol is highlighted with a blue border.

 

Foreground Color: This is the color to use for the shaded parts of the symbol. The foreground color can be changed by pressing the Foreground Color button. When this button is pressed the Color form will be displayed. Using this form, a basic color can be selected or a custom color can be specified.

 

Background Color: This is the color to use for the unshaded parts of the symbol. The background color can be changed by pressing the Background Color button. When this button is pressed the Color form is displayed. Using this form, a basic color can be selected or a custom color can be specified.

 

Fill Size: The fill size is used to expand or condense the symbol before it is drawn on the log. The size of the symbol is multiplied by the fill size and then the symbol is drawn. For example, a fill size of 2 will result in the symbol being doubled in size. The fill size must be greater than 0.

 

Top Line Style: The Top Line Style button is used to change the line style for the top symbol boundary in the symbol column. If the bottom depth of the symbol is specified this line style is also used for the bottom boundary.
