  author={Imrich Ku{\vs}n{\'i}r},
Nerastné suroviny Vietnamu Vietnam je bohatý na nerastné suroviny, ktoré sa nachádzajú prevažne na severe krajiny. Ložiská bauxitov, fosfátov, vzácnych zemín (REE), majú svetový význam. Ale i zásoby celého radu ďalších surovín (ropy, uhlia, zlata, železných rúd, chromitu, cínu, ilmenitu, medi, grafitu, atď.) sú významné, ekonomicky ťažiteľné a ich potenciál je obrovský. Za uvedené nerastné bohatstvo je „zodpovedná“ rozmanitá geologická stavba krajiny. Taktiež i morfológia a klíma (vlhk… Expand
Gemstones from Vietnam: An Update
GEMS & GEMOLOGY FALL 2012 Vietnam, with an area of 335,000 km 2, occupies the eastern side of the Indochinese peninsula. Most of the country’s northern and central regions are mountainous, reachingExpand
Metals in Sediment Cores from Nine Coastal Lagoons in Central Vietnam
Problem statement: After being dramatically hit by war events, Vietnam is presently experiencing a huge economical and social development. However, very few data, relative to pollution levels andExpand
The 40Ar–39Ar dating of biotite in ore veins and zircon U–Pb dating of porphyrtic granite dyke in the Nanyangtian tungsten deposit in SE Yunnan, China
Abstract The Nanyangtian tungsten deposit is located in the Laojunshan Sn–W polymetallic metallogenic province in SE Yunnan, China. Tectonically it is located in the conjunction of the Cathaysia andExpand
General characteristics of rare earth and radioactive elements in Dong Pao deposit, Lai Chau, Vietnam
One of the important rare earth deposits is the Dong Pao localized in Lai Chau province, West-North of Vietnam. Generally, the deposit is composed of two parts, the lower and the upper. The lowerExpand
Optical and Luminescence Spectroscopy of Varicolored Gem Spinel from Mogok, Myanmar and Lục Yên, Vietnam
We studied 12 crystal fragments of natural spinel from Mogok, Myanmar and Luc Yen, Vietnam. All samples were crystal fragments of various shapes and sizes and several of them had gemological quality.Expand
A Comparative Study of Different Machine Learning Algorithms in Predicting the Content of Ilmenite in Titanium Placer
In this study, the ilmenite content in beach placer sand was estimated using seven soft computing techniques, namely random forest (RF), artificial neural network (ANN), k-nearest neighbors (kNN),Expand
Assessment and source identification of As and Cd contamination in soil and plants in the vicinity of the Nui Phao Mine, Vietnam
The arsenic concentration between soil and plant samples was determined to be a positive correlation, while the Cd concentration showed a negative correlation, implying that As and Cd have different geochemical behavior based on their sources. Expand
Rare Earth Elements and Other Critical Metals in Deep Seabed Mineral Deposits: Composition and Implications for Resource Potential
The critical metal contents of four types of seabed mineral resources, including a deep-sea sediment deposit, are evaluated as potential rare earth element (REE) resources. The deep-sea resourcesExpand
Application of electromagnetic transient method for Zn–Pb exploration at the Cho Dien–Cho Don District, Bac Can Province, North Vietnam
Effectiveness of transient electromagnetic method (TEM) used for the localization of Pb–Zn ore bodies at the Cho Don deposit, province Bac Can, North Vietnam is appraised based on the modellingExpand
From mantle to critical zone: A review of large and giant sized deposits of the rare earth elements
Abstract The rare earth elements are unusual when defining giant-sized ore deposits, as resources are often quoted as total rare earth oxide, but the importance of a deposit may be related to theExpand
