10) The principal proponent of the theory is Thomas Gold (1920-2004), who achieved fame for his 1992 paper "The Deep Hot Biosphere" which proposed an abiogenic origin of coal, oil, and gas deposits.
At the same time, the information gained through this research has implications for fundamental science--demonstrating that abiogenic reactions that may have generated prebiotic organic molecules in the early earth continue to play a significant role in the production of hydrocarbons in Precambrian Shield crystalline rocks.
These issues include: i) the potential for abiogenic production of organic matter and the significance of this to our understanding of the timing of life's origins; ii) the timing of oxidation of earth's atmosphere; and iii) the continued expansion of our understanding of the capabilities and limits of microbial fife.
Barbara Sherwood Lollar, a geologist at the University of Toronto, says the new study provides "excellent scientific evidence" of the formation of abiogenic hydrocarbons in the mantle.
The former is the common growth morphology of abiogenic aragonite and often results in extensive lateral inter-growth, producing fanlike aggregates of misaligned needles.
Recent, and ongoing, studies at Kidd Creek have yielded valuable insights into understanding abiogenic versus biogenic sources of methane in the Earth's subsurface (Fig.
