Unique teaching aid for structural/general geology. This Morris Model is a geologic block model created by geologist and artist Ron Morris.  It is original, handmade and has unique design features. The model not only illustrates dip-slip faulting, but also has removable upper layers to show how tilted strata become offset in plan view during normal and reverse faulting. Its approximate dimensions in the un"displaced" position are 11.5 inches long, 8 inches high, and 4.5 inches wide.  It weighs 29 ounces, slightly less than 2 pounds. The block has a tilted dovetail slide in the middle, allowing the blocks to slide up and down.  The upper parts of the block are of tilted strata and there are two removable layers on each side.  The lower part of the model has folded strata and an intrusion creating a contact aureole.  The model is richly colored and uses standard lithological symbols. This Morris Model is one of five existing prototypes handmade and illustrated by Ron Morris.  It is made of strong gator board covered by printed panels and coated in spray acrylic.  The central slide is made of tough, thick acrylic.  The upper layers are attached by hidden neodymium magnets, and the dovetail slide has magnets positioned along it so that the sliding blocks will rest in several different positions.  There is even a stop built into the bottom of the block to prevent accidental slide of the hanging wall block off the model.  The base has rubber feet to inhibit damage to the lower surfaces. The original illustrations cover all surfaces, including the undersides of the removable layers.  The artwork is copyrighted by Ron Morris.
