June 12- July 17
Geological Agency, Bandung, Indonesia
NTA-4 is now complete. During the first week of the event, the Throughflow team met in Bandung for a series of lectures on modern methods for paleoenvironmental interpretation for one week. We are very grateful for the kind support of the Indonesian Geological Agency (Ministry of Energy and Mineral Resources) as hosts of the event. During the workshop we discussed the use of various fossil groups (algae, bryozoans, foraminifera, pollen, and molluscs) for interpreting past environments and looked in detail at how distribution of clastic and mixed carbonate-clastic facies can provide useful insights into paleoenvironments in the throughflow study areas in East Kalimantan. Thanks to Irfan Cibaj (Total Indonesie) for presenting his new work on the sedimentology and sequence stratigraphy of the thick sections near Samarinda. All ESRs were given the opportunity to present progress reports on their own research, and during the weekend we made a geotouristic excursion to Gunung Papandaya, a 2,662 m-high active volcano in West Java. The complementary and transferable skills component for NTA-4 was concerned with careers for geoscientists in the petroleum industry, and we were fortunate to be invited for a visit to the Core Laboratories offices in Jakarta. CoreLab is a leading provider of services to the petroleum industry and we were able to meet with their biostratigraphic and sediment processing teams. On June 21, the team traveled to East Kalimantan for applied field training. The main field party worked on study sites included the same sections worked up during NTA-2 in addition to newly discovered sites in Bontang, Bengalon, and Sankulirang. A stratigraphy team was deployed to perform intensive sampling on long sections in Samarinda and south of Balikpapan in the region of Tanagrogot. A second satellite team traveled north to Tanjung Redeb to explore the carbonate units in the basin north of Mankalihat. Approximately 5000 kgs of samples were shipped to Europe and data from this field training event is being worked as a series of collaborative projects by ESRs and other team members.
