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.
4], are consistent with an abiogenic kinetically-controlled polymerization reaction.
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.
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.
