The Modern And Ancient
Mahakam Delta
A Technical Field Trip for Geosciences Personnel
Re-scheduled from March 31-April 5, 2003
to
June 30 - July 5, 2003
Leaders : Stefano Mora, Marco Gardini and Agung Wiweko (TotalFinaElf).
Fee : IPA Members US$ 1350, Non-members US$1450 (including Jkt-Bppn-Jkt airfare,
land/ sea transportation, helicopter, hotels, meals, refreshments and hand-out).
Limit : 17 Persons (3 seats are available)
The Modern Mahakam Delta is one of the best examples of a deltaic depositional
environment that is both easily accessible for research and relatively undisturbed by
large scale human activities. The subject of numerous studies and publications, the
Modern Mahakam Delta is a mixed fluvial-tidal dominated delta developed since the last
Holocene still stand approximately 5-6000 years ago. The major depositional
environments of the Modern Mahakam Delta including the delta plain, distributaries
channels, the delta front and the distributaries mouth bars are accessible by boat.
The distributaries mouth bars, which are exposed above sea level during low tide,
present a unique opportunity to walk upon and make observations on the sediments and
sedimentary structures of the mouth bar.
The Ancient Mahakam Delta is exposed in large Miocene aged exposures in the vicinity
of the city of Samarinda. These outcrops reveal the ancient deltaic environment and
allow for a comparison between modern and ancient delta features. The presence of
both ancient and modern deltaic depositional systems in the same locality presents a
unique opportunity to more fully understand these complex and economically important
systems.
On the evening of June 30 participants will fly from Jakarta to Balikpapan where
they will stay in the Dusit Hotel. The next day participants will travel by bus to
the Mahakam Delta, over fly the delta by helicopter and travel by speedboat to stay in
the Bumi Senyiur Hotel in Samarinda. Wednesday, Thursday and Friday will be spent
examining delta features and outcrops based from Samarinda. At the end of Friday's
field work participants will return to the Dusit Hotel in Balikpapan for the night
prior to returning to Jakarta in the morning of July 5th.
The IPA Modern and Ancient Mahakam Delta Field Trip is made possible by
TotalFinaElf.
