but...what about the ABSTARCT?

Abiogenic Hydrocarbon Production at Lost City Hydrothermal Field

Low-molecular-weight hydrocarbons in natural hydrothermal fluids have been attributed to abiogenic production by Fischer-Tropsch type (FTT) reactions, although clear evidence for such a process has been elusive. Here, we present concentration, and stable and radiocarbon isotope, data from hydrocarbons dissolved in hydrogen-rich fluids venting at the ultramafic-hosted Lost City Hydrothermal Field. A distinct “inverse” trend in the stable carbon and hydrogen isotopic composition of C1 to C4 hydrocarbons is compatible with FTT genesis. Radiocarbon evidence rules out seawater bicarbonate as the carbon source for FTT reactions, suggesting that a mantle-derived inorganic carbon source is leached from the host rocks. Our findings illustrate that the abiotic synthesis of hydrocarbons in nature may occur in the presence of ultramafic rocks, water, and moderate amounts of heat.

My criticism was intended to be limited to WND’s incorrect restatement of Proskurowski’s work. His work is very important - it could change the order in which events need to happen to have the building blocks of life on earth.

I’m sorry if it sounded like I was criticizing anything else. Jerome R. Corsi has a book on oil he is trying to sell and it irritated me to see him misrepresent like this.

The only consolation is that Coursi doesn’t even to seem to realize that if his fake headline were true, it would undercut book.

BTW, you mentioned Thomas Gold. He was brilliant - discovered the magnetosphere, explained pulsars and a lot more. But his ideas on oil not coming from fossil fuels was part of his steady state earth theory that did not pan out. That doesn’t diminish his other work.
