The studied area is placed south of the copper plant Baia Mare and was under the impact of gaseous emissions for many years. Heavy metals pollution and landslide caused by pedogenetic conditions were the factors that led to the limitation of land use for agriculture. Based on the physical and chemical characteristics and soil composition profile there were identified these types of soil: eutricambosol, typical luvosol, stagnic, gleyic luvosol and

Tellurides are significant minerals in gold deposits both as gold carriers and as indicators of PTx-conditions. In the Inner Carpathians belt tellurides are abundant in most deposits of the golden Quadrilateral (Apuseni Mountains) and sporadic in the Banska Stiavnica zone and the Zlata Bania zone. In the presenr paper we describe for first time altaite and tetradymite occurences in the Baia Mare district proved by e-probe data. Altaite (PbTe) was

The intrusive rock from Nistru zone represents the subvolcanic suite of the igneous activity from the southern part of the Gutâi Mountains. The subvolcanic magmatic rocks from Nistru zone follow, in succession, the phase of Sarmatian pyroxene andesites. They are spatially associated to the volcanic rocks, being distinguished by morphological and structural aspects, as well as by petrographic types. The relations between the main types of magmatic

Ag-Bi-sulphosalts are reported from Cu-rich ores within base metal mineralization situated beneath Au-ores below level 750-800 m in the Cremenea vein of the ªuior epithermal vein deposit, Baia Mare region, Romania. Microanalytical data show the presence of a homogeneous unnamed phase with empirical composition [(Ag0.81Cu0.12)0.93Pb0.91(Bi1.11Sb0.06)1.17(S2.98Se0.02)3], showing light Bi-enrichment relative to ideal AgPbBiS3. Intergrowths of galena

The concentration and distribution of Pb, Cu, Zn and Cd in the soils from Zlatna and Copşa Micã (Romania) highly polluted by metallurgical activity, have been studied in the soil profile for different types of soils related with the physical and chemical properties of the soils. In Zlatna area, there have been studied the Aluviosol, Dystricambosol and Alosol types and in Copşa Micã area the Aluviosol and Phaeozem types. Content of humus, pH,

The pollution of the soils with heavy metals, Pb, Cu, Zn and Cd, was studied on a surface over 20.53km2 of Baia Mare. The total concentration of heavy metals was measured in the upper horizon for the entire surface of Baia Mare city and for each pedogenetical horizon within the soil profiles up to 1.20 m depth in the industrial zones. In both industrial areals Romplumb and Cuprom texture, pH, cation exchange capacity, base saturation, total carbon,

Extensive compositional heterogeneity is displayed by Pb-Sb-Au tellurides from the type locality at Sacaramb. These phases are collectively considered as varieties of nagyagite in the absence of crystal chemical data confirming the presence of distinct, but topologically closely related compounds. Chemical heterogeneity is seen relative to 'normal' nagyagite, with close to the ideal composition Pb3[Pb1.8(Sb1.1,As0.1)1.2]∑3S6(AuTe2), which is the

The concentration of the heavy metals in the soils from the strong affected zones because of the mining and metallurgical industry, Baia Mare and Zlatna (Romania), is significant due to the high values of the contents and association of the four metals Pb, Cu, Zn, Cd. The efficacy of the natural zeolites in heavy metals immobilization from the studied soils was evaluated in experiments in which the plant growth was observed. Heavy metals contaminated
