Features of a Stratigraphical Survey phase

The principal features of a Stratigraphical Survey phase are:

a)  Determination of depth of ground water, thickness, extent and approximate identity of strata to the required depth below the ground level,

b)  Collection of soil, rock and ground water samples for positive identification of material in the strata, and

c)  To make observations and certain minor field tests which will assist in the  determination  of condition  of samples and estimation of physical properties  of  the material.
