Mineralogical considerations on the topstratum of some mine tailings from the Fundu Moldovei area, Romania
Journal Title: Analele stiintifice ale Universitatii "Alexandru Ioan Cuza" din Iasi - seria Geologie - Year 2011, Vol 57, Issue 2
Abstract
The present study was conducted on a number of 14 tailings samples collected from the topstratum (0–20 cm depth) of three mine tailings deposits located within the Fundu Moldovei mining perimeter, Romania, namely Dealu Negru, Prașca I and Prașca II. The main objective of the study was to determine the mineralogy of these tailings by means of XRD, as well as to establish a link between the mineralogical composition and the conditions in which the tailings have been deposited. The Powder XRD analyses showed that the main minerals are quartz and Fe-rich chlorite, while the accessory minerals are muscovite-illite, sometimes pyrite or albite. The trace minerals identified were the following: albite, pyrite, jarosite (resulting from the weathering of pyrite), talc, gypsum and stilpnomelane.

New data on the Early Cretaceous between Gura Sadovei and Pojorâta (Rarău Syncline, Eastern Carpathians, Romania)
The Early Cretaceous (Bucovinian Nappe) deposits have been mapped only on the external flank of the Rarău Syncline, where they form a coarse clastic succession (breccias, conglomerates and sandstones) with very poor faun...
Geochemical distribution of selected trace elements in the soil-plant system from Mănăila mining area, Romania
This study presents the geochemical distribution of several trace elements (TE) (Ni, Cu, Zn, As, Pb) in a soil-plant system, taking into account the lingonberry, a shrub most widely spread around the Mănăila mining regio...
Spatial modelling of quality parameters for the shallow groundwaters of the Moldavian Platform
The aim of the present study is to estimate the continuous spatial distribution for certain quality (contents of Na+, K+, Mg2+, SO4 2-, HCO3 - and TDS) related to the shallow groundwaters of the Moldavian Plateau. The an...
