Mineralogie descriptiva

, 2005
In the book we have selected and described the most important minerals from the point of view of spreading and participation in the composition of the terrestrial crust and in terms of economic and scientific significance. The book was adopted the latest concepts on mineral systematic model proposed by IMA (International Mineralogical Association). The

Iron Sulfides Produced by Thermococcales: An Iron Detoxification Mechanism

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Thermococcales, archaea from hydrothermal vents, promote iron sulfide precipitation, enabling survival in iron‐rich environments. Some cells become encrusted in pyrite and do not survive mineralization, while surviving cells activate metal detoxification genes. This biomineralization process allows the population to withstand toxic iron concentrations,

Redox behavior of tin in aluminosilicate melts: Implications for the fining process

International Journal of Applied Glass Science, Volume 17, Issue 1, January 2026.
Abstract Aluminosilicate glasses are widely used in everyday applications and can be seen as building blocks of modern technology, from display screens to glass‐ceramics. However, due to their high viscosities, gas bubbles can only be removed from aluminosilicate melts at high temperatures, leading to significant energy costs.

Transport of heavy minerals and heavy anthropogenic particles in the Rio Sella catchment and along the adjacent coast, northern Spain [PDF]

Eiszeitalter und Gegenwart
The Rio Sella in northern Spain drains a catchment area of around 1200 km2. It originates in the Picos de Europa and erodes a variety of outcropping lithologies, mainly of Palaeozoic and minor Mesozoic to Cenozoic age. These rocks include siliciclastics,

Kindberg, the fifth meteorite fall in Austria: A weakly shocked L6 chondrite breccia with high‐pressure phases

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 17-38, January 2026.
Abstract A bright fireball was seen at 4:46 a.m. CET on November 19, 2020, over Austria, and also eye witnessed in Italy and Germany. The resulting Kindberg meteorite was the fifth well‐approved meteorite fall in Austria, and all rocks represent ordinary chondrites.

Mid‐Infrared Spectroscopy of Lunar High‐Ti Basaltic Glassy Analogues

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Laboratory‐based mid‐infrared (MIR) spectroscopy of terrestrial and planetary analogue materials, combined with chemical and spectral insights from mission‐derived data, provides critical tools for advancing our knowledge of planetary surfaces.

Chemical weathering of the volcanic soils of Isla Santa Cruz (Galápagos Islands, Ecuador) [PDF]

, 2014
We present a study on weathering of volcanic soils using 43 profiles (131 horizons) sampled in Santa Cruz Island (Galapagos Islands). Several weathering indices, based on chemical composition, are used. Since the geological material is highly homogeneous

Bio-, Magneto- and event-stratigraphy across the K-T boundary [PDF]

Determining the time and the time structure of rare events in geology can be accomplished by applying three different and independent stratigraphic methods: Biostratigraphy, magneto-stratigraphy and event-stratigraphy.
