SITE SUMMARY
GAB-05B
Site: GAB-05B
(GAB-05B seismic)
(GAB-05B track line)
Priority:
1
Position: 33°25.2122´S, 127°36.1382´E
Water Depth: 488 m
Sediment Thickness: ‰3910 m
Approved Maximum Penetration: 600 m
Seismic Coverage: Intersection at SPs 995 and 13195 on
AGSO Line 169/13
Objectives:
The objectives of GAB-05B are to
- Recover
a detailed record of shelf-edge siliciclastic deposition
(at a "distal" site compared with Site GAB-06B)
to evaluate the sedimentary response to Paleogene
sea-level fluctuations and to evaluate the complex
interaction between sea-level variation, accommodation
space, and subsidence.
- Determine
the characteristics of cool-water carbonate facies within
the Neogene succession (Sequences 2 to 4).
- Determine
paleoceanographic parameters within a shelf-edge setting
in Sequences 2 to 4, to complement other components of
the shelf-to-basin transect.
- Evaluate
sea-level control on Neogene facies within an upper
slope/shelf-edge setting (cf Sites GAB-03B and GAB-04B).
- Evaluate
the diagenetic history and processes within Neogene
facies in an upper slope/shelf edge setting.
