Title

BIRPS (British Institutes Reflection Profiling Syndicate) Banda seismic data (1992-1993)

Abstract

In 1992, BIRPS joined with the Indonesian Marine Geological Institute to record two long multichannel normal-incidence reflection profiles, one of which is DAMAR, the other TIMOR, and one short profile (API) close to the volcano Gunung Api. The survey provides a modern analogue to tectonics hypothesized to have occurred across the Iapetus suture zone of northern England 450-400 Ma. The Banda Arc of Indonesia near the island of Timor is widely recognized as the premier example of the active subduction of continental crust and lithosphere beneath oceanic lithosphere. The crossing of a modern island arc and close passage to active volcanoes was intended to image reflections associated with magma in the crust and uppermost mantle.

Lineage

Deep multichannel seismic data were acquired and processed. M/V GECO-kappa survey ship was used towing 92-channel hydrophone streamer. An airgun array of 7324 cubic inches was 70 m wide producing 97 bar peak-to-peak pressure at frequencies of 3-62.5 Hz. DAMAR was shot at 100 m intervals to a recording time of 37 s in total. The TIMOR provided redundancy and higher spatial resolution near Timor, and used a 50m shot interval to record 17±24 s records. This second profile was effectively continued to the Australian coast when the Australian Geological Survey Organisation collected a series of 16 s profiles on their continental shelf the next year. Line 12 of this survey was reprocessed using the same parameters used to process TIMOR and provides an example of lithospheric reflectivity from an Archaean shield margin that has undergone extension.
