Mas Iwan, Sebenarnya ada beberapa paper yang menyebutkan pengangkatan Central Range Borneo atau yg biasa kita kenal sbg Kucing High itu sejak Late Oligocene, tetapi memang kebanyakan merujuk pada periode Early Miocene karena memang baru pada Early Miocene, Kucing High mulai efektif menjadi provenance sedimen di sirkum Borneo, termasuk Mahakam Delta.
Tetapi sebenarnya sebelum Kucing high terangkat-pun, Borneo sudah punya Meratus High di selatan dan Mangkalihat Ridge di utara yg bisa jadi sediment source-nya Kutei. Artinya gak menutup kemungkinan bahwa ada deltaic sediment yang lebih tua dari Early Miocene. Semoga bermanfaat, Ferry -----Original Message----- From: Iwan B [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 21, 2007 2:37 PM To: iagi-net@iagi.or.id Subject: Re: [iagi-net-l] Delta East Kalimantan Kok agak bingung ya, kalau delta Mahakam baru terbentuk setelah uplift Upper miocene.....sebenarnya delta mahalakam yang mana ya??? setahu saya delta mahakam (terutama yang lower kutei) sudah ada sejak early miocene, dan upliftnya sendiri bukannya lebih tua dari upper miocene (Kucing High ??)
