1. Stratigraphic Section
A sequence of vertical rock layers in the sedimentary rock in the law of superposition

2. How to do… stratigrafi measurement section is:
obtain detailed data from thesequence of litology unit (formation, group, members, etc.) 
Obtaining the precise thickness of each unit stratigrafi 
To obtain and learn stratigrafi relationship between a rock and stream sedimentation in the vertical direction in detail, analyze the environment for settling

3. Field Implementation Procedure
Ideally be done at the end of the geological mapping, in which information about the geological conditions such as the distribution of rock, geological structure is known can be chosen so that the orbit-crossing the ideal (the outcrop, is not subject to the structure, etc.) 
At the same time with the mapping, especially in areas difficult to reach

5. Planning 
The position of a layer (strike and dip), is steep, sloping, vertical or horisontal.Arah track akan wherever that may be perpendicular to the moment. 
Must be examined whether the moment and slope layer is continuous or permanent change. The things mentioned above are important in determining the method of calculation and measurement.

11. Measurements on flat areas
Formula: T = dt ∂ x sin      T = thick layer  dt = the distance measured in the field       ∂  = Corner slope layer

12. The measurement of the direction of the gradient layer
Formula: T = d sin (∂ - s) (Figure9.5b)                Q = d sin (s - ∂) (Figure9.5c)                T = Thickness layer                S = slope Corner                ∂ = slope layer

13. Measurement layer opposite direction with the slope
Formula: T = d (Figure 9.6c)                 Q = d sin (∂ + s) (Figure 9.6b)                 Q = d sin (180 - ∂ - s) (Figure 9.6d)                 T = Thickness layer                 ∂ = layer tilt angle                 s = slope Corner
