Glenn Morton trained as a geologist with the people who proposed that model that you posted. Then he made the "mistake" of getting a job with an oil company that involved him having to deal with real geological data on a daily basis. In his words...
But eventually, by 1994 I was through with young-earth creationISM. Nothing that young-earth creationists had taught me about geology turned out to be true. I took a poll of my ICR graduate friends who have worked in the oil industry. I asked them one question.
"From your oil industry experience, did any fact that you were taught at ICR, which challenged current geological thinking, turn out in the long run to be true? ,"
That is a very simple question. One man, Steve Robertson, who worked for Shell grew real silent on the phone, sighed and softly said 'No!' A very close friend that I had hired at Arco, after hearing the question, exclaimed, "Wait a minute. There has to be one!" But he could not name one. I can not name one. No one else could either. One man I could not reach, to ask that question, had a crisis of faith about two years after coming into the oil industry. I do not know what his spiritual state is now but he was in bad shape the last time I talked to him.
"Glenn R. Morton has a long history of making and repeating fallacious arguments against creationist scientists. For instance, he has been distorting the content and significance of my 1979 paper[1] on isotopic dating for some 25 years. Despite his having been repeatedly corrected during this long period of time, he continues to present it to the unwary. It is for this reason that this reply has been written. Otherwise, Morton’s transparently specious argument is not even worth dignifying with a reply, for which reason no earlier formal response had been written."

Is this the same Glenn Morton?
