Figure 3-7. Lithologic percentage log. 



REPRODUCTION If it is anticipated that a number of copies 



OF STRIP LOGS of a strip log will be needed, the original log 



can be made in some form that is easily 

 reproducible. Commercial log companies, which make a few to several hundred 

 copies of the lithologic logs, first make an original on transparent material that 

 will produce good copies in an Ozalid or similar machine. 



At least one company makes a color reproduction by photographic methods, 

 but the process is rather expensive.
