IN2018_V08    - is a Marine National Facility voyage

Title: The Balleny mantle plume: key role in Tasmania-Antarctic breakup?

Voyage details on MNF site: https://mnf.csiro.au/en/Voyages/IN2018_V08

Period: 2018-12-26 23:00 to 2019-01-09 23:00 UTC

Duration: 14.00 days

From: Hobart To: Hobart

Region: Southern Ocean; Tasman Sea

Ship: Investigator (RV) [details]

Description: RV Investigator research voyage in2018_v08, titled "The Balleny mantle plume: key role in Tasmania-Antarctic breakup?" Objective 1. Collect seafloor and subseafloor geophysical data. This data will be used: a. To identify seafloor fabric, which will help refine plate reconstructions of the Tasman Seas in areas difficult to constrain from magnetic anomaly lineations alone; b. To obtain comprehensive multibeam and backscatter coverage of the seamounts and their morphology to understand tectonic setting, eruptive style, palaeo-water-depth and sedimentation patterns; c. To assist in dredge site targeting by identifying sediment-free scarps and slopes; d. Sub-bottom profile data will be collected to provide additional context for the nature of the near-surface sediment and geological structure. Objective 2. Dredge volcanic samples from seamounts along the proposed Balleny Seamount chain. Ashore, samples will be: a. Ar/Ar Dated to determine the age and duration of seamount formation; b. Volcanic coherent rocks will be described macroscopically, petrographically and mineralogically to classify and characterise the type volcanism on the seamounts. Comparing the nature and origin of volcanism at different sites may reveal multiple episodes of volcanism or variations in volcanic activity in time and space. c. Volcaniclastic rocks will be described macroscopically, petrographically, mineralogically and include ash morphology descriptions. This work will constrain submarine/subaerial eruption/emplacement and style of transport d. Sedimentary rocks will be described macroscopically, microscopically and petrographically. Additional U-Pb geochronology will be undertaken as will micro- and macro-fossil palaeontology. These analyses can constrain depth, environment, and time of deposition, important for constraining the timing and rate of subsidence.
