General characteristics of rare earth and radioactive elements in Dong Pao deposit, Lai Chau, Vietnam
Get PDFOne 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 lower part is composed of dolomite, limestone and intrusive rocks, while the upper part of the profile is represented by a weathered zone containing soil and fragments of mixed barite-fluorite ores. The concentrations of natural radionuclides, chemical compositions of ores, including rare earth elements (REE) in solid samples, were determined by gamma spectrometer equipped with a HPGe detector, laser ablation inductively coupled plasma mass spectrometry (LA ICPMS) and activation method, respectively. In the samples taken from the ore bodies within the weathered zone the REE concentration is about 10 wt.% and both 238U and 232Th amount to 0.01 wt.%, while in the samples from the hard part of ore the REE and 238U as well as 232Th contents amount only to 0.3 wt.% and 0.001 wt.%, respectively. So the enrichment of the REE and natural radioactive elements in the deposit is a consequence of the weathering processes. The water samples were taken from the streams, natural tap and thermal water intakes localized in the studied deposit and surrounding region. The 238U, 234U, 228Ra, 226Ra concentrations in the water samples were prepared by the adequate radiochemical procedures and measured using an alpha spectrometer coupled with silicon semiconductor detector and a/b liquid scintillation counter. In the stream water, the concentrations of both 226Ra and 228Ra vary from 100 to above 300 mBq/L, while in the natural tap and thermal waters they amount to tens mBq/L. The concentration of 238U, 234U in the thermal water is 80 and 110 mBq/L respectively, while in the surface water concentrations of uranium isotopes are below 30 mBq/L.References Bureau Veritas Canada, 2015.

Zettel (27), 25 November 1995 (NHMW).</p> <p> <b>Diagnosis.</b> Male: fore femur incrassate (ratio length/width variable, in apterous males about 2.70–4.02), with a bifid subapical tooth; fore tibia without indentation on inner surface (Figs. 74, 75). Male genitalia moderate in size: pygophore sub-ovate; proctiger elongate; paramere slender, falciform with pointed apex (Fig. 37); endosoma as in Chen & Nieser (1993: Figs. 101, 102). Female: sternum 7 large, constricted laterally, medially produced tongue-like lobe (with diagonal lateral margins) on posterior margin, sometimes directed dorsad, completely enclosing the genitalia (Fig. 76).</p> <p>Size: body length about twice as width: apterous males: length 4.60–6.30, width 2.28–3.14, macropterous males: length 6.40–8.20, width 2.34–2.97; apterous females, length 4.40–5.80, width 2.41–3.14, macropterous males: length 6.20–6.90, width 2.52–2.67.</p> <p> <b>Remarks.</b> <i>Metrocoris acutus</i> belongs to the <i>M. nigrofasciatus</i> species group, as defined by Chen & Nieser (1993), on the basis of the following character states: male fore femur incrassate, ventral surface of apical part indented with a single or bifid sub-apical tooth; paramere slender and curved; female sternum 7 large, with median lobe produced. Two species belonging to the <i>M. nigrofasciatus</i> group are found in Vietnam, <i>M. acutus</i> and <i>M. nigrofascioides</i>. Males of these two species can be separated from each other by the structures of the fore leg, parameres and endosoma. By contrast, the females of the two species are very similar to each other, especially in regard to colour pattern. However, they can be separated by size (the females of <i>M. acutus</i> are slightly larger), shape of the median lobe of sternum 7 (tongue-like in <i>M. acutus</i>, sub-rectangular in <i>M. nigrofascioides</i>), and pubescence on the inner surface of the hind trochanter (more distinct and longer in <i>M. nigrofascioides</i>).</p> <p> <b>Distribution.</b> Vietnam: Dien Bien, Son La, Quang Ninh, Hoa Binh, Ninh Binh, Ha Tinh, Cao Bang (first record), Hai Duong (first record), Thanh Hoa (first record), Nghe An (first record), Lao Cai, Lai Chau, Bac Kan, Vinh Phuc (Fig. 139).
