ITCZ) or equatorial trough. This line of convergence near the equator is also discernible in a map of streamlines (Figure 12.2; Note 12.A). It is actually a band a few hundred kilometres wide, enclosing places where winds flow inwards (are 'confluent') and subsequently rise convectively.he movement of the ITCZ across South Africa (Figure 12.1) is complicated by the land's shape, elevation and location, and there is a southerly spur called the Zaire Air Boundary (ZAB). Similarly, there is a spur over South America.

The geometry of joints refers to the orientation of joints as either plotted on stereonets and rose-diagrams or observed in rock exposures. In terms of geometry, three major types of joints, nonsystematic joints, systematic joints, and columnar jointing are recognized.Nonsystematic joints are joints that are so irregular in form, spacing, and orientation that they cannot be readily grouped into distinctive, through-going joint sets. Diagonal joints â Joints which typically occur as conjugate joint sets that trend oblique to the fold axes. 2  Strike joints â Joints which trend parallel to the strike of the axial plane of a fold. 3  Cross-strike joints â Joints which cut across the axial plane of a fold.
