Demonstrate the principle of superposition
and the concepts of transgression,
regression, and compression with this
economical model. Students can construct
a logical sequence of five sedimentary
layers in a compression box, then apply
a convergent force with the plunger in
the box to explore each concept. The
applied force causes the layers to fold
and then fault. It includes all materials and
instructions. Size: 11 3/4”L x 3 3/4”W x 7
7/8”H.
