Formula for Zs

[steve447]

Sat the 17th last night and this question came up, i had a stab at it and i beleive the answer is .....Zs = Ze+R1+R2 however i still cannot find it in the regs book.
Can anyone point me to the reg number
Cheers

The Big Red Book 612.9 page 160. Does not actually show Zs=Ze =R1=R2. Page 361 Appendix 14 Shows Equation method.
On Site Guide Page 87 10.3.6 shows it all.

If (Zsd) is the decompacted thickness of the sediment and (Zs) is the fully lithified thickness of the sediment package.

dunno what you're on , but can you send me some.

well. that would make life simple. measure Ze and you got the lot in 1

Thanks
I see what your saying now about it being in the text of page 361 app 14 , however it still doesnt actually state R1 R2 or Ze on that page.
The question was basically what is the formula for Zs and had 4 different versions of the equation above, so i was frantically looking for that equation to jump out at me and i now know it never would have.

i had the same problem trying to find the equation in the 16th edition.

The correct one should have looked something like this.....Zs = Ze+(R1+R2). The brackets are important otherwise it wont add up correctly.
