The case study presented here deals with the Pb-Zn-Cu skarn ores hosted in Rosas Shear Zone (RSZ), a highly strained domain located external zone of Sardinian Variscan chain. RSZ is characterized by several tectonic slices Cambrian limestones within strongly folded and foliated Cambrian-Ordovician siliciclastic succession, intruded late granites mafic dykes. Based on geological mapping, structu...

Abstract We report detailed mineralogy and geochemistry of hydrothermal mounds chimneys in the TA25 West vent field (TA25 WVF), a newly discovered magmatic–hydrothermal system Tonga (Tofua) arc. Chimney samples are classified as sulfate- or sulfide-rich, based on major sulfide, sulfosalt, sulfate minerals. The former type represents simple mineral assemblage predominance anhydrite/gypsum + bari...

The purpose of this study was to examine associations among bone mineral density, osteopenia/osteoporosis, body mass index (BMI), and body composition in patients with heart failure (HF). A total of 119 patients (age = 61 ± 12 years, 65% male) underwent dual-energy X-ray absorptiometry scans to determine bone mineral density and body composition. In multivariable linear regressions, BMI, relati...

In the present study effect of feeding area specific mineral mixture on the serum mineral status of cattle in different agro climatic zones (plateau, plain and hills) of Chhattisgarh state was studied. The soil and fodder mineral status of different zones were analyzed. Macro minerals were below desired level in soil of hill region followed by plateau and plain whereas Mg level in soils of diff...

background: to investigate the relationship between renal stone formation and osteoporosis. methods: eight hundred thirty healthy subjects aged between 20 and 76 years were randomly selected from 50 clusters to take part in the study. of these, 68 (8.2%) had a previous history of renal stone disease. all participants underwent clinical exami nation and bone mineral densitometry of the lumbar sp...

background : the role of minerals on parasite persistency and the interaction between minerals and animal responses to the parasite infestation is not clear. for these reasons, the present re­search was aimed to compare copper, zinc and iron status in sheep with parasitic myocarditis and healthy ones in 2009. methods : blood and heart tissue samples were collected from 145 slaughtered sheep and...

A study was conducted to evaluate the effects of dietary inorganic and organic trace minerals in two levels of supplementation regarding performance, diarrhea occurrence, hematological parameters, fecal mineral excretion and mineral retention in metacarpals and liver of weanling pigs. Seventy piglets weaned at 21 days of age with an average initial body weight of 6.70 ± 0.38 kg were allotted in...

UNLABELLED Bacteria play important roles in mineral weathering, soil formation, and element cycling. However, little is known about the interaction between silicate minerals and rhizobia. In this study, Rhizobium yantingense H66 (a novel mineral-weathering rhizobium) and Rhizobium etli CFN42 were compared with respect to potash feldspar weathering, mineral surface adsorption, and metabolic acti...
