Asbestiform tremolite within the Holocene late pyroclastic deposits of Colli Albani volcano (Latium, Italy): Occurrence and crystal-chemistry [PDF]
arXiv, 2013 This work relates the occurrence and the characterization of fibrous tremolite within the latest pyroclastic deposits of the Colli Albani (Alban Hills) volcano, to the south-east of Rome (Italy). These mineralizations were observed during a systematic rock-sampling undertaken to complete the geological survey for the new 1:50 000 map of this volcanic ...

The relationship between cellular protein content and selenium accumulation in freshwater microalgae
Integrated Environmental Assessment and Management, EarlyView.Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Pyralspite Garnets in Volcanic Rocks
The Journal of the Geological Society of Japan, 1955 A pyralspite garnet from a cavity in rhyolite at the Thomas Range, Utah, U., S., A., was analysed as shown in Table 1., It is high in Mn content, being mainly composed of the spessartine and almandine molecules., Pyralspites occurring as porphyritic minerals in volcanic rocks are poorer in Mn than those from cavities and lithophysae in volcanic rocks ...

Late Pleistocene–Holocene environmental fluctuations of southern Chihuahua Desert, Mexico
Journal of Quaternary Science, EarlyView.ABSTRACT Paleoenvironmental reconstructions from the Mexican Chihuahua Desert based on biological proxies are scarce, creating a gap in our understanding of the ecological responses to climate change in this water‐scarce region. Here, we present a paleoenvironmental reconstruction based on geochemical data and biological proxies such as ostracods and ...
