.... Within its boundary, 18 multipurpose dams are strategically deployed for agricultural, hydropower, and water delivery. The mountainous topography, marked by steep slopes, constrains the reservoirs’ capacity, a challenge particularly pronounced in the central region of Vietnam and, more specifically...

... of north Central Vietnam. Based upon the stratigraphic distributions of 24 foraminiferal taxa, including Citaella dinarica , Citaella ? deformata , Endotriada tyrrhenica , Endotriadella wirzi , Endotriadella pentacamerata , Pilamminella grandis , Pilammina cf. densa , and Triadodiscus cf. praecursor , we...

...Thi Thu Hien-Dinh; Duy Anh Dao; Tam Tran; Michael Wahl; Eckardt Stein; Reto Gieré Abstract A potential lithium deposit has been discovered in the La Vi mining district, located in Quang Ngai Province, Central Vietnam. The Li-rich rocks (average contents: 1.3 ± 0.9 wt.% Li 2 O) are highly...

... at Lam Thuy enhances the dataset of Silurian graptolite-bearing localities in central Vietnam and advertises the wide utility of graptolite assemblages for biostratigraphical correlation of lower Palaeozoic strata in northern and central Vietnam. The Long Dai Formation is composed of up to circa...

... of rocks; development of sericitization and feldspathization in the metasomatic zones; presence of granite porphyry dikes; presence of chalcopyrite, molybdenite, and gold in ores. Prospectivity of Central Vietnam in relation to mineralization of gold in general and its particular ore formations...

...Nobuhiko Nakano; Yasuhito Osanai; Masaaki Owada Abstract Clinopyroxene in ultrahigh-temperature mafic granulites from the Kontum Massif in central Vietnam records multiple metamorphic stages, manifested as exsolution textures (quartz rods and orthopyroxene + hornblende + plagioclase needles...

...Elizabeth A. Nagy; Henri Maluski; Claude Lepvrier; Urs Schärer; Phan Truong Thi; A. Leyreloup; Vu Van Thich Abstract The Kontum massif of south-central Vietnam has long been classified as lower continental crust of Precambrian (Archean) age. U-Pb zircon and 40 Ar/ 39 Ar biotite ages from...

...Gwang H. Lee; Joel S. Watkins ABSTRACT The Phu Khanh Basin, offshore central Vietnam, is the only undrilled basin on the Vietnam margin of the South China Sea. Analysis of multichannel seismic data indicates that the Phu Khanh Basin follows a typical rift-margin development: faulted basement...

... acquired across the N-S trending margin off Central Vietnam. These data enable us to recognise structural features striking N060 degrees E. The seismic data show progressive crustal thinning from NW to SE: large tilted blocks in shallow water (Triton ridge), smaller blocks under a thin sedimentary layer...

...) taking into account the evolution of the surrounding drainage systems in comparison to the basin sediments. Drastic provenance transformation on the SCS sedimentary patterns has been first discovered that source of Central Vietnam was replaced by Pearl River networks. Rapidly changing local provenances...

... areas and sedimentary basins over time. We conducted coupled U-Pb dating and Lu-Hf isotope analysis of detrital zircon in fluvial sediments along northern and central Vietnam and sediment core in the western Yinggehai–Song Hong Basin in order to characterize the potential sources, investigate...

... used in recent PSHA studies in Vietnam ( Pham and Nguyen, 2019 ). The three groups represent the active crustal regions from the United States and Taiwan. The final group representative the stable continental areas from Central East North America (CENA) and Korea. This group comprised three equations...

... rocks from the Truong Son and Tam Ky-Phuoc Son zones in southern Laos. Our study, along with Early Paleozoic igneous suites from southern Laos, central Vietnam and the Malay Peninsula, suggests an arc–back-arc system along the northern margin of Gondwana. Supplementary material: Tables of zircon U–Pb...

..., with additional minor contributions from central Vietnam (eastern Indochina block) and possibly the Songpan–Garze block. Variations in the dominant detrital zircon populations within stratigraphic successions display an increasing contribution from the Red River since the middle Miocene. This resulted from...

..., a small-scale rift basin in central Vietnam, was used as a conceptual model for the distribution of lithofacies, including source rock types, in the 2-D models. Exploration targets and drilled direct HC indicators (DHIs) are mainly located in the tectonically disturbed postrift succession. Modeling...

...Tong-Dzuy Thanh; Philippe Janvier; Ta Hoa Phuong Abstract A yunnanolepiform antiarch (placoderm fish) is recorded from the Givetian Dong Tho Formation of Quang Binh Province, central Vietnam. This and other fishes from the same locality occur in marginal marine, detrital facies, with plant remains...
