Calculation Parameters for the Cementation Theory

The Parameters $\rm S_{\rm n}$ and $\rm S_{\tau}$ are calculated as follows:

\begin{eqnarray}
\rm S_{\rm n}&=&\:\rm A_{\rm n} (\Lambda_{\rm n})\:\alpha^2\:+\...
 ... \left[{{2\:\rm S_{\rm h}\:\phi}\over{3\:(1-\phi)}}\right ]^{0.5};\end{eqnarray}
(21)

where $\rm G$ and $\nu$ are the shear modulus and Poisson's ratio, respectively, of the sediment. The hydrate properties are given by its shear moduli $\rm G_{\rm h}$ and Poisson's ratio $\nu_{\rm h}$. The parameter $\alpha$ is the ratio of the cemented contact radius to the grain radius in case of hydrate evenly enveloping the sediment grains.
