Difference between Primary and Secondary lithology style
APPENDIX A - 307
The Style is usually set to Primary if basic or dominant lithology is displayed. Nonrepeated
symbols such as qualifiers or accessories are best displayed with the
Primary Style option not set (secondary style).
Contact Dictionary:
If lithology beds are displayed in Primary style the top and bottom boundaries of a
bed are graphically displayed as a straight line. It is possible to change the line style
to indicate a certain type of contact between adjacent lithology beds. Top and
bottom contact style will be stored as part of the data as well.

Contact styles are organized in libraries (dictionaries) and referred to by a code

how to create a contact dictionary
