Abstract:

A description of mobile Ni contents in various subtypes of calcareous black soils from the area of the mountain massif of Rajac, is given in the present paper. A hundred soil samples were analysed in all, originating from four subtypes of calcareous black soil (organogenic, organo-mineral, brownized and loessivized black soils). The extraction of mobile Ni was carried out with 1.0 N HCl and its content was determined by atomic absorption spectrophotometry. The obtained results indicate that mobile Ni content in the investigated soils varies within a wide range, from 5.0 to 251.3 mg/kg that it

Abstract:

Chromite placer is widely distributed in Quaternary sediments located around the Nui Nua ultramafic massif in Thanh Hoa province, Vietnam. The long-term mining works targeting chromite placer in this area have left a huge amount of waste sludge, up to tens of millions of tons. The paper aims to introduce a deposit potential and distribution of cobalt- and nickel- bearing minerals within the waste sludges generated from the chromite placer mining operations around the mines situated near the Nui Nua ultramafic massif in Thanh Hoa province, Vietnam.

Abstract:

A comparative description of two sulfide copper-nickel deposits confined to the middle massifs is given: Aguablanca (Iberian Massif, Spain) and Shanuch (Kamchatka Massif, Russia). It was shown that both deposits are spatially and genetically related to small intrusions and dikes of mostly basic composition. Ore bodies are funnel-shaped, lenticular, stock-shaped, and vein-like, and are spread to significant depths. Both deposits contain rich sulfide copper-nickel ores as well as relatively poor; the ore texture is predominantly breccia or massive, seldom disseminated. Ore mineral composition in

Abstract:

Ultramafic areas are critical for nickel (Ni) phytomining due to the high concentration of this element in their soils and the number of hyperaccumulators they harbor. The aim of the present study was to evaluate the potential of the Morais massif, an ultramafic area in Portugal, for phytomining using the hyperaccumulator species Alyssum serpyllifolium subsp. lusitanicum. Soil samples and A. serpyllifolium specimens were collected in four locations of the Morais massif.

Psychotria (Rubiaceae) is the second largest genus of flowering plants in New Caledonia.

Four of them are described and illustrated here: P. fambartiae, P. ireneae, P. nigotei and P. veillonii. Robust morphological characteristics were found to distinguish these four from other New Caledonian species. Psychotria veillonii, which is known only from the massif of Tiébaghi, might already be extinct as a result of intensive nickel mining in the area.

Abstract:

The accumulation of heavy metals, primarily from the soil, takes place in the water and fodder plants. Sources are pesticides, polluted air and precipitation. Hazardous chemical elements in certain quantities enter plants from soil. It should be added that ballast substances from mineral fertilizers containing heavy metals are also found in the soil. It has been established that on the flat-foothill massif of the North Caucasus, the constant component of solid precipitation are such elements as chromium, nickel, lead, manganese and silver. Cadmium was not detected in most precipitation samples

The Piip Volcano is a submarine volcanic edifice occupying the central part of the Volcanologists Massif in the southwestern Bering Sea, with two tops, southern and northern. The minimum depth of the northern top is located at 368 m, and of the southern at 464 m. Active hydrothermal venting occurring at both summits of the volcano supports diverse biological communities, including animals specific for chemosynthetic habitats. In benthic organisms inhabiting the northern and southern tops of the Piip Volcano, for the first time, we examined distribution patterns of the following trace elements:
