Help students plan lectures and debates, and provide them with information concerning scientists who are willing to speak on different theories of creation. Provide reference materials for students who would like to do term papers on origins-related topics and who would be interested in including the creationist viewpoint. Sandstone dikes in granite are anomalous in terms of current assumptions of a detrital origin of sand grains in sandstones. In Colorado some such mechanism must have been capable of forming a vertical wall 1000 feet high and 300 feet thick in granite. The common tendency for sandstone dikes to pinch and swell seems to indicate that the idea of sediments infilling cracks is an oversimplified or incorrect explanation.
Cracks formed in a host rock ought to have parallel side-walls.
Another problem with the conventional theory of sandstone dikes is the origin of the vertical stratification which sometimes occurs. Flow structures in sandstone dikes. He suggested, however, that this structure probably originated in a manner entirely different from normal cross stratification, generally thought to involve deposition from rapid currents. Perhaps the assumption of an exogenous origin of sand grains in dikes should be reexamined. Rocks under pressure subjected to faulting could be altered in the vicinity of faults.
