Petrography and mineral chemistry of metamorphosed mantle peridotites of Nain Ophiolite (Central Iran)

Journal of Economic Geology, 2017
Introduction Study of the petrology of the ophiolites as the relics of ancient oceanic lithosphere, is a powerful tool to reconstruct Earth’s history. Mantle peridotites have mostly undergone alteration and serpentinization to some extent.

Origin, Tectonic Processes, and Metasomatism of Serpentinite in the Shimanto Accretionary Complex, SW Japan: Possible Diapiric Intrusion of Serpentinized Oceanic Lithosphere

Tectonics, Volume 45, Issue 7, July 2026.
Abstract Serpentinite plays a major role in the geodynamics of subduction zones. However, the processes by which serpentinite is incorporated into accretionary complexes, and the extent to which it interacts chemically and physically with accretionary lithologies, remain unclear.

Borehole Waters From Hole U1601C (Atlantis Massif) Provide Constraints for a Deep‐Sourced Formation Water That (Could) Feed the Lost City Hydrothermal Field

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Hole U1601C, drilled during International Ocean Discovery Program (IODP) Expedition 399, reached a depth of 1,268 m below the seafloor (mbsf) in the Atlantis Massif (30°N, 42°W). This borehole represents only one of six boreholes that extends more than 700 m into oceanic rock, penetrating predominantly ultramafic lithologies, mostly composed ...

The Tremolite Isograd near Marble Lake, Ontario

, 1973
Marble, metavolcanic rocks, and pelite are found in a northeasterly trending belt near Marble Lake, in the Grenville Province, Ontario. The rocks have been metamorphosed to the lower amphibolite facies in the southwest, the grade increasing to the mid ...

Synthesis and characterization of tremolite asbestos fibres

, 2008
Fibres of Fe-free tremolitic amphibole were synthesized using hydrothermal conditions. The run products contained only minor amounts of one other phase, quartz, as determined by X-ray powder diffraction (XRPD).

Critical reappraisal of Balangero chrysotile and mesothelioma risk

Epidemiology, Biostatistics and Public Health, 2022
Background Balangero, 40 km northwest of Torino in the Piedmonte Region, was home to the largest and most active chrysotile mine in Europe operating from 1916 - 1990 and employed over 300 men at any one time.

Mesothelioma in Cyprus: the role of tremolite. [PDF]

Thorax, 1987
There is a chrysotile mine in the central mountains of Cyprus but no other appreciable source of industrial asbestos. Hence the island was thought to offer ideal conditions to seek pure chrysotile induced mesothelioma. The first reported case was a village woman whose lung tissue contained amphibole asbestos fibres, which were later identified as ...

P–T Modelling Constrains the Depth of Emplacement of the Porto Azzurro Pluton and Implies Minor Exhumation Caused by the Zuccale Fault (Island of Elba, Italy)

Journal of Metamorphic Geology, Volume 44, Issue 6, Page 440-469, July 2026.
ABSTRACT Understanding the pressure of emplacement of granitic intrusions is crucial to understanding the exhumation history of plutons and constraining the tectonic setting of magma emplacement. However, P–T and geochronological constraints from exhumed plutons are often characterized by large uncertainties, especially in shallow crustal settings with
