The Astrobiogeochemistry Laboratory (abcLab) is interested in exploring molecular and mineralogical biosignatures in ancient and recent Earth samples to provide evidence of early signs of life. Currently, in the abcLab, scientists are utilizing a lipid biomarker extraction and analysis method to remove organic material from geologic samples taken from several sites around the world including Australia, the United States and West Wales. This study focuses primarily on samples collected from the Mochras borehole on the Cardigan Bay Basin, West Wales, dating back to the Early Jurassic to identify biomarkers such as hopanes (derived from prokaryotes) and steranes (derived from eukaryotes) to reconstruct an ancient ecosystem. It is anticipated that this lipid biomarker extraction procedure will be used for the research conducted on the geologic samples sent back to Earth from the Mars 2020 Rover Mission set to launch in the summer of 2020.
