The sequence of rock types is more useful, but hardly an infallible guide to correlation.
Even where the ten systems may be present, geologists recognize individual systems to be incomplete.
The entire geologic column, composed of complete strata systems, exists only in the diagrams drawn by geologists!
Several erroneous notions have been attached to the geologic column. The geologic column was constructed by geologists who, because of the weight of the evidence that they had found, were convinced of the truth of uniformitarian theory and organic evolution.
The following are the ten most common misconceptions. It may sound surprising, but the standard geologic column was devised before 1860 by catastrophists who were creationists.1 Adam Sedgewick, Roderick Murchison, William Coneybeare, and others affirmed that the earth was formed largely by catastrophic processes, and that the earth and life were created.
Hundreds of locations are known where the order of the systems identified by geologists does not match the order of the geologic column.
Strata systems are believed in some places to be inverted, repeated, or inserted where they do not belong.
The assumptions and correlations within the 'geologic column' are largely make-believe and wishful-thinking and cannot be substantiated by empirical science; despite this, many under-knowledged school and college teachers teach this system verbatim.
he ten strata systems that geologists use (Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, Cretaceous, and Tertiary) compose the "standard geologic column" and are claimed by many to contain the major proof of evolutionary theory.
Overturning, overthrust faulting, or landsliding are frequently maintained as disrupting the order.
In some locations such structural changes can be supported by physical evidence while elsewhere physical evidence of the disruption may be lacking and special pleading may be required using fossils or radiometric dating.
Sandstone, limestone, dolomite, shale, chert, salt, conglomerate, coal and other rock types are not diagnostic of specific strata systems.
