11. Summary of the new finding of the thesis:
The thesis focused on lithological characteristics and laws of distribution on the Cretaceous stone on Phu Quoc Island then classification of facies, sequence stratigraphy, sedimentary cycles and evaluation of oil and gas prospects them.
(1). Clarifying the law of evolution of sedimentary cycles on the basis of quantitative analysis and petrographic characteristics of symbiotic minister. There are four groups of Cretaceous rockon Phu Quoc island : conglomerate, sand stone, silt stone, clay which are distributedin spacelawin the direction ofstockflowfromwest to East onPhu Quoc Island and fining up ward time to time and four group facies in cretaceous sediment on Phu Quoc island: group of conglomerate on mountainousrive - midland; group ofgeneralssandyriverdelta; group ofgeneralssandyintertidalzone; group ofgeneralformulaalluvialclay, clay in bayou. All of the facies group are distribution ofthe cyclein thestratigraphicwellE2.
(2). Dividethecomplexcharacteristicsandthesedimentarysystemdomainonthe basis of aminister andsedimentcharacteristicsinrelation tosea levelchangeandtectonic movements:There are 10 sequence, 20 parasequence set and 40 parasequence of Cretaceous sediment on Phu Quoc island. Each sedimentation rate corresponding to a group of facies, each facies group to a group of parasequence set or parasequence. The change from gravel – sand facies, silt stone aluvi to sanstone on tidal under section curves show oscillations of sea level change from regression to transgression.
(3). Research petrographic characteristics - physical quantitative analysis and general stratigraphic diversity is the scientific basis for the construction of premises rated life quality floor, floors and floor contains certain. Special help sort out the quality sandstone Kreta collector in the right direction for the search for oil and gas exploration and swimming Kreta southwestern region of Vietnam: Cretaceous sedimment on Phu Quoc island has poor of sinh daauf, poor to very good colector, the best on early cretaceous Quartz sand stone, Quartz - lithic sand stone on beach and lagoon. containthetype ofcollectorfrompoorto very good, most potentialKretasandstonefloorearly in thesingle-group mineralsquartzsandstone, quartz -liticform intropicalcoastalenvironmentandcoastalsanddike.
