Masalahnya mungkin ada turbiditnya tapi apakah ada hc chargenya...? kalau
enggak jadi turbidit tapi isinya water....
problem lainnya apakah patahan jadi seal atau conduit dari hc migrasinya
...

Tegak lurus Mahakam ini maksudnya sebelah timurnya Mahakam (sejajar
sungai/progradasinya) ?
Kalau aku perhatiin dari present day topografinya sepertinya justru di
sebelah utara mahakam akan banyak terdapat turbidit karena kalau dilihat
strukturnya akan lebih banyak patahan di utara present day Mahakam Delta
ini, ketimbang sebelah timurnya yg reltif "quite". Nah sebagai trigger
(slope failure) tentunya fault ini dapat menjadi penyebab longsornya delta
topset yg kaya akan source dan mungkin juga coarse sediment.
Jadi di utara Mahakam ini lebih bagus utk deepwater (turbidite)
prospektivity ketimbang timurnya ... ya kah ?
