Biro kursus PP-IAGI telah sukses mengadakan diskusi Luncheon Talk pada tanggal 29th May 2012. Pembicara dalam acara ini adalah Tim Charlton (Consultant Regional Geologist), dengan judul : RE‐DEFINING THE ALLOCHTHON IN TIMOR - “Structural‐stratigraphic relationships at the boundaries of the Lolotoi metamorphic complex in Timor‐Leste, and implications for the Mutis Complex in Timor Barat, NTT”.
Luncheon Talk yang dihadiri oleh sekitar 40 peserta ini diadakan di Ruang CANDI KALASAN, GRAND SAHID JAYA HOTEL Jl. Jend. Sudirman Kav. 86, Jakarta. Acara dimulai pukul: 11.30 AM hingga 14.00 PM. Slide presentasi dapat diunduh dibawah.
Berikut Ringkasan dari presentasinya:
There is long‐standing controversy over the origin of metamorphic complexes in Timor: do they represent Banda forearc or Australian continental basement? New fieldwork results from Timor‐Leste suggest stratigraphic linkages between the Lolotoi metamorphic complex and Australian‐affinity cover sequences, while structural mapping and borehole data also suggest an Australian basement origin. Although there are subtle differences between the Lolotoi Complex in Timor‐Leste and the Mutis Complex in West Timor, broadly similar metamorphic conditions and ages suggest an essentially similar origin, although with a somewhat different tectonic setting (the Mutis Complex occupies high‐level thrust sheets, whereas the Lolotoi Complex is found in a low structural position). A new model is proposed with the Mutis‐Lolotoi Complex originating in the Australian continental margin through a previously‐undocumented phase of Paleogene crustal‐scale extension. This new interpretation requires that the Cretaceous‐Paleogene Palelo Group (the main cover succession to the Mutis Complex in West Timor) also originated on the Australian plate rather than the usually interpreted Banda forearc origin.
