Geological Schizophrenia or Simply Being of Two Minds?

Had a chat with a geologist mate who mentioned a discussion he had with a hydrology consultant recently. Among topics discussed were the source of the water for the Great Artesian Basin (GAB), the overlying Pedirka Basin and abiotic oil theory. Seems the consultant prefers the standard theory that these artesian water deposits are formed from rainwater in the uplands, and definitely not from the subsurface as an upper mantle lower crust emission as described by the late Lance Endersbee. Yet my mate told me that the same consultant was excited over the theory of abiotic oil.

How contradictory could one be? Definitely a case of being of two minds.

And it appears the NT Geological Survey believes there exists a connection between the Pedirka Basin and the underlying GAB, a theory which my interlocutors thought risible. The standard of geological thinking seems to be following that found in climate science – accelerating rapidly downwards, a progression not necessarily being consciously aimed at, I suspect.

About Louis Hissink

Retired diamond exploration geologist. I spent my professional life looking for mineral deposits, found some, and also located a number of kimberlites in NSW and Western Australia. Exploration geology is the closest one can get to practicing the scientific method, mineral exploration always being concerned with finding anomalous geophysical or geochemical data, framing a model and explanation for the anomaly and then testing it with drilling or excavation. All scientific theories are ultimately false since they invariably involved explaining something with incomplete extant knowledge. Since no one is omniscient or knows everything, so too scientific theories which are solely limited to existing knowledge. Because the future always yields new data, scientific theories must change to be compatible with the new data. Thus a true scientist is never in love with any particular theory, always knowing that when the facts change, so too must he/she change their minds.
