Geological imprint of methane seepage on the seabed and biota of the convergent Hikurangi Margin, New Zealand: Box core and grab carbonate results
(Elsevier, 2010)Short box cores (to 30 cm bsf) and seafloor carbonate grab samples were acquired at mapped hydrocarbon seep sites (600–1200 m water depths) during the 2007 RV SONNE SO191 cruise on the Hikurangi Margin offshore eastern ... -
Miocene tubular concretions in East Coast Basin, New Zealand: Analogue for the subsurface plumbing of cold seeps
(Elsevier, doi:10.1016/j.margeo.2009.03.021, 2010)The uplifted accretionary prism of East Coast Basin, in Hikurangi Margin, North Island, New Zealand, exposes late Miocene slope mudrocks (Whangaehu Mudstone, < 10% carbonate) in coastal cliffs north of Cape Turnagain that ... -
Tubular carbonate concretions as hydrocarbon migration pathways? Examples from North Island, New Zealand
(Ministry of Economic Development (online), 2006)Cold seep carbonate deposits are associated with the development on the sea floor of distinctive chemosyn¬thetic animal communities and carbonate minerali¬sation as a consequence of microbially mediated anaerobic oxidation ... -
Tubular Carbonate Concretions from North Island, New Zealand: Evidence for Hydrocarbon Migration and the Subsurface Plumbing System of Cold Seeps
(The University of Waikato, 2009)Among the cold seep research community, it is now appreciated that tubular carbonate concretions are important indicators of hydrocarbon migration in the subsurface. In the last few years, several publications have documented ... -
Tubular concretions in New Zealand petroliferous basins: Lipid biomarker evidence for mineralisation around proposed miocene hydrocarbon seep conduits
(Wiley-Blackwell, 2010)Trapped organic compounds (lipids) have been analysed in tubular carbonate concretions and their host sediments in Miocene deep water mudrocks from coastal outcrops in East Coast Basin and Taranaki Basin of North Island, ...
