3D geological cross-section model3D Model
This model is a block diagram designed to show students how the vertical subsurface structure relates to a surface map. The top surface of the model represents half of the map area students are given that they have to construct a cross-section from (the front face of this model). Students are required to make corrections for apparent dip which are evident in this model.
The structure of the model includes a sequence of Carboniferous rocks folded by an upright, non-plunging similar fold. The Carboniferous rocks are unconformably overlain by a tilted series of Triassic rocks. Both sequences are cut by a northwest dipping dolerite dyke. Initial view is looking toward the northeast.
Another model almost identical to this, but with a concentric (parallel) fold style is available here.
