Serpentinite in the Śnieżnik Massif :

open access: yesGeoscience Records, 2015
The paper presents a locality related to the occurrence of serpentinite body from the western slope of Żmijowiec in the Śnieżnik Massif. On the basis of field observations and numerous literature references, I provide a detailed geological description of this site and discuss the origin and tectonic settings of the serpentinite body.

Experimental study of trace element release during ultrahigh-pressure serpentinite dehydration [PDF]

open access: yesEarth and Planetary Science Letters, 2014
Subduction of serpentinite is envisaged to play a key role in volatile and element recycling at convergent plate margins, but there is currently little known about the composition of the fluid phase(s) released by devolatilisation of deeply subducted ...

Serpentinite

Geology Today, 2012
Serpentinites are metamorphic rocks formed from the alteration of ultramafic igneous rocks. Their precursors largely consist of clinopyroxene, orthopyroxene, olivine and a member of the spinel group, along with other accessory minerals. Serpentinization can be produced through the percolation of fluids of different origins.

ON THE NATURE OF HYDROCARBONS IN SERPENTINITES

Geology and mineral resources of Siberia, 2023
The article presents the unique results of the study and photographs of the core of serpentinites saturated with hydrocarbons (HC). During the core study, the rock mineral composition was investigated, the order of mineral formation as well as the nature of serpentinite saturation with hydrocarbons was determined,pyrolytic analysis of samples was ...

Alpine‐type Serpentinites from the Auckland province—I. The Wairere Serpentinite

Journal of the Royal Society of New Zealand, 1973
Abstract The Wairere Serpentinite, exposed over 650 m along the trace of the Waipa Fault near Piopio, lies close to the boundary of the marginal and shelf facies of the New Zealand Geosyncline and hence close to Hatherton and Sibson's magnetic junction anomaly.

The Sierra Nevada serpentinites: the serpentinites most used in Spanish heritage buildings

Geological Society, London, Special Publications, 2014
Abstract Serpentinites from Sierra Nevada (Granada, south of Spain) have traditionally been used as ornamental elements in historical buildings, both indoors and outdoors. The cathedral, the Palace of Charles V, the Royal Chancellery in Granada and some others are good examples of their use.

Investigation of the processing of serpentinites

Theoretical Foundations of Chemical Engineering, 2017
The processing of serpentinites by sintering them with caustic alkali has been shown. The majority of silica is leached from the resulting sinter and is recovered from the concentrate magnesium using solutions of strong mineral acids. Amorphous silica is leached from the residue with alkaline solution.

Tectonic significance of serpentinites

Tectonophysics, 2015
At plate boundaries, where deformation is localized along centimetre- to kilometre-scale shear zones, the influence of serpentinite on tectonic processes is linked to its unique rheological properties. In this paper wereview the physical properties of serpentinites and their role in tectonic processes.
