metabasites and serpentinites of the ophiolitic sequence of the gimigliano-mount reventino unit(calabria, southern italy), also known as greenstones, are employed and marketed for building and ornamentalpurposes since prehistorical times. the main topic of our research focuses on the occurrence, within the abovelithotypes, of asbestiform minerals that may be potentially harmful for human health...

Multi-isotope fingerprinting (sulphur, oxygen and strontium isotopes) has been tested to study the provenances of medieval and Renaissance French and Swedish alabaster artwork. Isotope signatures of historical English, French and Spanish alabaster source quarries or areas reveal highly specific, with a strong intra-group homogeneity and strong inter-group contrasts, especially for Sr and S isot...

In this study we have measured exposure levels to quartz in different parts of the slate industry in Alta, Northern Norway. Full shift personal samples were collected from the breathing zones of outdoor and indoor workers in the slate quarries and a slate factory. The quartz content of respirable dust was between 7 and 41%. The slate factory had the lower quartz levels although 41% of total and...

Lapis lazuli has been used for more than 7000 years for the manufacture of precious objects and jewels. The main quarries for this stone are still active in Afghanistan, but there are other quarries that could have been exploited since antiquity in the Pamir mountains (Tajikistan), in Pakistan and in Siberia. For this reason a provenance study of lapis lazuli could provide answers to some impor...

Eye injuries often occur in the workplace in low and middle-income countries, particularly in the construction, agricultural, mining, and manufacturing industries. Even if there are safety regulations in these industries, their enforcement is often unsatisfactory, and owners are not required to provide safety equipment. In 2005, Christian Medical College in Vellore, India, conducted a pilot stu...

Rapid population growth and increasing demand for the modern settlement has led to the increase of environmental pollution. Limestone quarry is one among the activities that affect environment and ecosystem in Pemba Island-Zanzibar. Quarrying activities brought an inevitable destruction to the environments ranging from excavation, soil and land degradation, loose of biodiversity and water pollu...

Abstract We have documented quarries in Miocene limestone the Vienna Basin (Austria), Hundsheim Mountains, Leitha Mountains and Rust Hills high-resolution airborne laser scanning data orthophotos aiming for a diachronic quarry inventory since Roman period. The study region was divided into 6 regions of whole area as well each separate were analyzed concerning different rock types, mean, minimum...

The application of several magnetic parameters to ochre samples has found that they can be used to characterize samples from known ochre quarries. This technique also allows the sourcing of ochre found in archaeological contexts and provides an alternative to geochemical methods of provenancing ochres. Simple magnetic parameters (susceptibility and isothermal remanence) are effective in discrim...

The Auckland aggregate market is estimated to be 7.2 million tonnes a year. Sixteen major quarries supply this market. Because of the number of suppliers and the variety of products, planning in this complex environment is difficult. Winstone Aggregates is the largest producer of rock products in Auckland. It owns nine quarries and supplies slightly more then half of the region's aggregate need...
