Collection of rock and mineral samples from the sea and islands of North Vietnam

10/09/2021

The collection of rock and mineral samples representing the waters and islands of Northern Vietnam was carried out from 2015 to 2020 in the range of waters from Mong Cai to Hai Van Cape and islands. This is the product of the component project code BSTMV.25/15-18 led by Prof. Dr. Tran Duc Thanh, Institute of Marine Resources and Environment.

The component project collected 7 samples of magmatic rock, 23 samples of sedimentary and metamorphic rocks, 5 samples of loose sediments and cave stalactites, 15 samples of loose marine sediments, and 14 samples of minerals. A total of 68 samples with 936 specimens, each sample has 5 - 15 specimens. The samples are numbered, analyzed and identified, currently preserved at the Institute of Marine Environment and Resources, awaiting to be transferred to the Vietnam Museum of Nature.

Where samples are placed

Being carried out from 2015 to 2020, the project achieved the following results: The collection includes 68 samples along with analysis results for sample identification, contributing to additional information on geological and mineral features in the Northern sea region, being a testament to the value of geological diversity in the waters and islands of the North of Vietnam. Samples collected in the Northern sea region are the initial basis for selection and display at the museum for visitors and popularization to the community. The collected samples are materials for further studies on petrology, and minerals in the Northern sea and islands. The set of sample documents in the long term also has the value of affirming and proving national sovereignty over the northern sea and islands of Vietnam.

The project has contributed to improving the capacity of the governed agency in skills, methods of surveying and studying geology and geo-environment in the Northern sea and islands. It has been accepted by the State Council for Science and Technology, evaluated for scientific and practical significance, and rated Pass.
