Duties and Reports of the Subsurface Geologist

6. Depth in feet of the interval sampled. 



1, Under "Type" indicate whether "Ditch," "Core" (give number 

 of core), "A-1 Core" or "S.W.C." The report should have the 

 descriptions in depth sequence. Even if an interval is cored and 

 described, the ditch sample corresponding to the cored interval 

 should also be described. (See description for ditch samples and 

 core No. 57, interval 8965-75.) Sidewall cores and/or A-1 cores 

 can be covered in a separate weekly well-sample report and, if 

 at all possible, should be described in a descending-depth order. 



8. All descriptions should follow a definite order when possible.

Use of abbreviations in core and sample des- 

 criptions is optional. If the geologist des- 

 cribing the cores prefers to write out the 

 full descriptive terms, he may do so with the 

 following results: 



Rec. 6 '8" 



3 '8" - SHALE, gray to dark gray, fairly hard, 



fissile, very slightly lignitic.
