In 2009, he published some of these ideas in the Journal of Creation 23(3):116–118.
His research shows that the salt pillars around the world are elegantly explained by the interaction of a melted salt magma with the waters of the worldwide Flood.
His Journal paper summarizes:
Large formations of rock salt are found on every continent around the world. Oil and gas are often associated with salt deposits, which can rise kilometers above the top of the main underground salt body. These salt deposits are commonly referred to as “evaporites” because they are considered to have been formed by the evaporation of sea water. The evaporite model requires the evaporation of hundreds of kilometers of depth of seawater, a process that would require vast periods of time, far longer than the biblical timescale. Consequently evaporites have been used as an argument against young-earth geology. However, there are major problems with the evaporite model such that it is totally inadequate to explain the thickness, volume, structure and purity of salt deposits. A more feasible model regards salt deposits as the product of igneous halite magma. Such magmas melt at geologic temperatures, flow readily, and account for the association of salt deposits with reserves of coal, oil and gas.
I like Stef’s model, and think it is far superior to the uniformitarian attempt to explain the evidence, which I was taught at university in my geology course. That model hypothesizes that hundreds of kilometres of seawater evaporated slowly in an enormous, shallow, secluded area of the coast, over millions of years.
