Research Interests

Dr. Corcoran investigates Earth's surface and atmospheric processes using the sedimentary rock record. A primary objective of her long term research program is to better understand the effects of climate, transport and recycling on sedimentary textures and composition from the granular level upward. Examining the evolutionary system controlling the nature of sedimentary deposits requires a combination of field observations, microscopic and high resolution sub-microscopic laboratory analysis of collected samples.

Dr. Corcoran has applied this approach to a range of geological problems from ancient to modern depositional sequences. Examples include studies yielding information on i) Precambrian atmospheric conditions as inferred from Canadian and South African sedimentary successions, ii) high rates of chemical weathering and recycling in tectonically active Paleozoic successions of New Zealand, and iii) the distribution and degradation  of plastic debris on marine and fresh water beaches.

In order to extract the evolution of Earth surface processes from sedimentary deposits, Dr. Corcoran integrates several techniques, which include: 1) field work, 2) major, trace and REE geochemistry of bulk sediment samples, 3) compositional analysis of amorphous grains and polymers using FTIR and SIMS, 4) textural analysis of grains using SEM and CL spectroscopy.
