Jun 11, 2020 Listvenite lode–gold associations are often located within or near major fault or shear zones, many of which are terrane boundaries ( Halls and Zhao, 1995 and references therein)./P In the central and southern parts of the Eastern Desert of Egypt, listvenite is commonly associated with highly tectonized, allochthonous ophiolitic serpentinites.

Listvenite lenses range from a few meters to several hundred meters in size with NE-trending direction.Listvenite and fuchsite listvenite with serpentinite relics generally shows shearing deformation.The ore-bodies were controlled by a ductile shear zone.

May 01, 2017 The term “listvenite” was proposed by Gustav Rose in 1837 for the green rocks from the lode gold deposits of the Miass ore region.Its root is based on the Russian name for a larch tree ().The term “beresite” was described for the first time at the Berezovskoe gold deposit in the Central Urals and its name derives from the deposit’s name.

The mineralogy and tectonic setting of listvenite are reviewed, taking into account the descriptions and classifications used in the literature.The petrography of listvenite and related rocks at Cregganbaun serves as a reference to illustrate the characteristics of true listvenite and closely related products of listvenitic alteration.

The occurrence of the quartz‐carbonate alteration assemblage (listvenite) in ophiolites indicates that ultramafic rock represents an effective sink for dissolved CO 2.

The occurrence of the quartz–carbonate alteration assemblage (listvenite) in ophiolites indicates that ultramafic rock represents an effective sink for dissolved CO2.However, the majority of earlier studies of ultramafic rock carbonation had to rely on the surface exposure of reaction textures and field relationships.Here we present the first observations on ultramafic rock alteration .

The rock ‘listvenite’ is named and defined by reference to historical observations and recommendations are made so that listvenite (s.) can be distinguished from related carbonate-rich alteration products of ultramafic rocks.The mineralogy and tectonic setting of listvenite are reviewed, taking into account the descriptions and classifications used in the literature.
