The Hoanh Bo Basin is a multiple period formed basin which associated with the tectonic mechanism due to activity of Chi Linh-Hon Gai and Trung Luong Faults during late Paleogene -early Neogene time.The filled continental sediments, comprising mainly polymictic conglomerates, sandstones, siltstones, claystones shales.Coarser-grained deposits predominate along northern western margins basin, while different types claystones, even sandstones occur in its center, as well southern eastern parts...
The Cao Bang Basin is the northernmost of basins related to Bang-Tien Yen Fault Zone in northern Vietnam. basin filled with a thick series continental deposits. However, exact age sedimentary basin infill has been under discussion for long time. Because new published data, authors have decided revisit this basin. Palynological data allowed us assign Lower Oligocene PC1 complex Shangcun Fm. (southern China). Among saccate grains gymnosperms, the domination Cathaya and Pinus was observed,...
The Ma river delta located in the North Central of VietNam is third largest ones Vietnam following Mekong Delta and Red River Delta. However, there are not many researches on sedimentary. This study aims to determine Characteristics Holocene sedimentary facies coastal plain Song based observation structure analysis grain size, diatom, flora, pollen 14C dating collected for drill core (LKTH2 borehole) from delta. Research results identify 08 consisting 02 transgression period 06 regression...
The Hoanh Bo Basin has developed over multiple periods since the Miocene period in association with tectonic activity of Chi Linh-Hon Gai and Trung Luong Faults. basin is filled Neogene continental sediments, comprising mainly polymictic conglomerates, sandstones, siltstones, claystones, shales. Coarser-grained deposits predominate along northern western margins basin, whereas different types sandstones occur its centre, as well southern eastern parts, toward Ha Long Bay. conglomerates are...
Abstract: Paleokarst, a karst landform developed in the geologic past and often buried by younger sedimentary rocks, has not received much attention Vietnam. Field surveys thin-section analyses have confirmed presence of paleokarsts two adjacent national parks Phong Nha - Ke Bang (Vietnam) Hin Nam No (Laos). They are mainly found types surfaces (karren, polje) filled fissures caves, on Middle Devonian (Givetian), Upper (Famennian), Lower Carboniferious Carboniferous Permian limestones. The...
During the Miocene-Pleistocene, generally sub-tropical to tropical warm and humid paleoclimate prevailed in Southeast Asia with a gradual cooling trend. The Truc Thon clay (TTC) mine presents interesting outcrops for sedimentological provenance analysis. present study uses results of geological investigation 16 wells at Thon. TTC has lens-shaped geometry, filled two bodies, including grey-white multicolor clay. Bulk mineralogy indicates predominance quartz relatively high amount...
The coastal area of the Ma river delta is formed by interaction continental and marine processes, between neo-tectonic activities exogenous natural factors human during Late Holocene. Using remote sensing geoscience research methods (granulometry, paleontology, geochemistry, clay mineralogy) geomorphological studies (geneses, morphology, dynamics) combined with field survey, this area, except denuded mountainous remnants, could be distinguished into 12 morpho-sedimentary units developed...
Located on the northern Vietnam onshore/offshore transition, Hoanh Bo Trough is an excellently exposed terrestrial Palaeogene sedimentary sequence that may be treated as analogue for regional interpretations of and structural evolution Song Hong Basin. The lies to north Basin west Beibuwan Basin, origin which are linked with South China Sea rifting. Field archival well sedimentological observations were made throughout succession Trough, samples collected palynological, petrographical,...
Based on original characteristics, the grained size surficial sediments bottom Tonkin Gulf was divided into 3 groups: provenance of related to igenous and sedimentwy rocks, are materials late Pleistocene weathering crust bioturbance materials. Especially, second group detailed classified by mineral chemical compositions, such as: lateritzed curdles, clastics rich in iron, Ca; cancite clatics.Sediments what originated from sedimentaJy rock distributed around Bach Long Vi Island at 50 - 60...
Kim Son coastal plain is a part of the Red River Delta located between Day and Can rivers. Over past 55 years, has been region with highest accretion rate in Delta. This study aims to clarify sediment characteristics plain. It structure typical tidal flat relatively straightforward tide-influenced sedimentary evidenced by field observation, sampling 70 hand-drilled boreholes, borehole logging analyzing 177 samples grain size. There are three zones be identified, including sand flat, mixed...
