The Neogene period (ca. 23.8 to 2.6 Ma) is divided into two main geological epochs – Miocene and Pliocene. During the Miocene epoch various geological changes on Earth including continuation of the continent drift and formation of the Antarctic Circumpolar Current. During Integrated Ocean Drilling Program (IODP) Expedition 317 four shelf-upper slope sites were drilled off the eastern side of the South Island of New Zealand in the Canterbury Basin, covering the sequence from the Eocene period to Recent.

Source Rock Analysis: Tmax and PI, U1352 (slope)
Transition: fresh/unstructured organic matter to kerogen
Good thermal maturity trends

U1352-SRA

Future work

A large number of samples from Expedition 317 are in Simon George's lab, and are avilablefor further research. So far, we have worked on biomarkers for source and thermal maturity in U1354 and U1352. There are many other types of analyses that could still be done.

Further, we are planning voyages on the new Australian research vessel, the RV Investigator, from 2014.
