Stick plots are a two-dimensional graphical representation of dip inclinations viewed as lines of apparent dip from a given direction onto a vertical plane against depth or time. They are usually prepared as two views perpendicular to each other, and are analogues to viewing geological features of a quarry wall. They are useful in the construction of cross-sections and helping to drive correlations. Commonly used, after suitable filtering and averaging, can be pasted onto seismic sections or well tracks to aid geometrical interpretations. Modern computer graphics allows colour coding of the sticks, corresponding with different manual dips.
