Betul sekali Pak Edison, splay Palu-Koro itu masuk ke bagian utara Suramana dan terus ke Mangkalihat. Sudah dipublikasi juga keberadaan flower structure di Makassar Strait itu di Proccedings IPA dua tahun terakhir (lihat paper2 Baillie et al, dan Fraser et al.).

Waktu dibuat model gravity (1999), kalo ngak salah density valuenya tinggi sekali ngak match kalo di gunakan density value untuk reef. Wah EMOI ganti strategi nih. Yah mungkin reef yang sama kayak Cepu ada disini. Oh ya, pak Awang kalo melihat komplek flower stucture di dekat Suramana ini, kayaknya sesar mendatar Palu-Koro langsung menerus ke Mangkalihat Peninsula? mohon infonya edison |---------+-------------------------------------> | | Ferdinandus.KARTIKO-SAMODR| | | [EMAIL PROTECTED] | | | | | | 06/06/2006 04:03 PM | | | Please respond to iagi-net| | | | |---------+-------------------------------------> >-------------------------------------------------------------------------------------------------------------------------------| | | | To: <[email protected]> | | cc: [email protected] | | Subject: RE: [iagi-net-l] SURAMANA (was : RE: [iagi-net-l] Block Sarumana) | >-------------------------------------------------------------------------------------------------------------------------------| menarik kalau memang menunjukkan batuan beku , melihat bahwa typenya conical mound yang mungkin lebih bersifat asam daripada basa..... kalau rifting kan harusnya basa , apa mungkin membentuk conical mound...?

Masih diperlukan verifikasi dari model antara seismic dan gravity/magnetik. Tampaknya feature dibawah sana lebih menunjukkan batuan beku, nampak conical mound feature dari seismic internal, juga tampak low domal mound feature yang diinterpretasikan sebagai aliran lava.. Bisa jadi sih reef akan tumbuh diatasnya. Dari data seismik, tidak menampakkan tanda-tanda seismik internal sebagai build up. Dalam seismik tampak sebagai reflection free. Di daerah Suramana dan Pasangkayu tampaknya Ponded Turbidite dari 3.5 Ma - 5.5Ma lebih berkembang. Slope Channel dan Basin Fan dari arah Kalimantan pada usia 10.5Ma - 5.5Ma (Late Miocene) juga diperkirakan sampe kesini. edison |---------+---------------------------> | | "Awang Harun | | | Satyana" | | | <[EMAIL PROTECTED]| | | com> | | | | | | 05/06/2006 01:47| | | PM | | | Please respond | | | to iagi-net | | | | |---------+---------------------------> > -------------------------------------------------------------------------------------------------------------------------------| | | | To: <[email protected]> | | cc: | | Subject: RE: [iagi-net-l] SURAMANA (was : RE: [iagi-net-l] Block Sarumana) | > -------------------------------------------------------------------------------------------------------------------------------| Pasangkayu dimenangkan Marathon.

Herry ----- Original Message ---- From: Awang Harun Satyana <[EMAIL PROTECTED]> To: [email protected] Sent: Monday, 5 June, 2006 12:19:52 PM Subject: [iagi-net-l] SURAMANA (was : RE: [iagi-net-l] Block Sarumana) Bu Yuriza, Apa namanya Blok Sarumana ? Saya pikir bukan Sarumana, tetapi SURAMANA, mengacu ke sebuah kota kecil Suramana di Sulawesi Tengah, di BD Donggala (dekat Palu). Blok Suramana terletak di utara Blok Pasangkayu. Dua-duanya ada di offshore area sebelah barat Sulawesi, sebagian masuk ke Cekungan Lariang, sebagian besar masuk ke Cekungan North Makassar Strait. Antara Lariang dan North Makassar Strait mestinya membentuk embayment (cekungan yang membuka ke arah laut lepas) - seperti halnya antara Kutei dan North Makassar Strait. Saya kebetulan pernah ikut tim MIGAS menilai Blok2 Pasangkayu dan Suramana. Paling tidak, ada tiga play yang bisa diharapkan berkembang di wilayah ini : (1) karbonat terumbu Oligo-Miosen yang duduk di horst-block - ini bisa saja bukan reef, tetapi seamount, hanya kelihatannya itu reef, (2) Pliocene fold belt - kelihatannya toe thrusting tak berkembang sebagus di sisi Kutei, (3) syn-rift Paleogen. Mengevaluasi blok ini harus menerapkan konsep pre-rifting Kalimantan-Sulawesi, drifting Sulawesi ke Timur, dan syn-orogenic sediments yang banyak mengkontribusi di post-Pliocene. Bloknya lumayan menarik, tetapi tantangannya besar. Walaupun berseberangan dengan Kutei deepwater, tak bisa seluruh konsepnya dibawa ke Suramana.
