Fibrous tourmaline from San Piero in Campo (Elba, Italy)
Published 2025-07-01“…On top of the radial aggregates of acicular single crystals, there are globular terminations formed by rose-shaped lath-like particles, which are made of a mixture of layer silicates.</p> <p>The most likely scenario for the formation of the studied tourmaline assemblage involves the miarolitic cavity fracturing due to a mechanical shock, the subsequent circulation of the highly reactive cavity fluids, and the leaching of accessory biotite in the surrounding pegmatite, which account for the overgrowth of the fibrous cap of dark Tur IIa and black Tur IIb on top of the prismatic elbaite. …”<p>An unusual variety of fibrous tourmaline, not previously described on the island of Elba, was studied using a multi-analytical approach, including powder X-ray diffraction, scanning electron microscopy, electron probe micro-analysis, Raman spectroscopy, and in situ B-isotopic analyses.

Isotopic signature of precipitation in the Elbrus region
Published 2023-04-01“…The results showed that precipitation in the Elbrus region in winter was associated with the prevailing transfer from the Atlantic, in summer – with the predominance of transfer from the regions of Central Europe, the Mediterranean and Black Seas. The Mediterranean Sea in all seasons was the area from which the air and moisture were transferred to Elbrus. …”The aim of the work was to study the isotopic characteristics of precipitation to establish the dependence of δ18O values on temperature at the time of precipitation and to get closer to understanding the processes that form the isotopic signature of the Elbrus snow cover and glacial ice.
