The chemical composition of Dunite includes MgO, SiO 2, Fe 2 O 3, CaO and Al 2 3. Olivine, which is the primary constituent of Dunite, comprises largely of Mg 2 SiO 4 and Fe 2 SiO 4.

Low‐temperature dunite hydration: evaluating CH4

Hydrous alteration of ultramafic rocks (serpentinization), such as peridotites, has been the focus of numerous studies because of its ability to produce bio‐available energy sources, especially methane (CH 4) and hydrogen (H 2).In the presence of trace metals (e.g., Fe, Ni, Co, Zn, Mn), CH 4 and H 2 may play important roles in the origin of life (e.g., Russell et al.

A study of thermal decomposition of antigorite from

Two varieties of serpentines, antigorite and lizardite originated from dunite and peridotite, respectively, were previously undergone heat treatment in the range from 396 to 1128 °C and then leached via an original approach to the acid processing of dehydrated serpentines. Because of unsaturated (weak) Si–O(Si) bonds existing in the serpentines structure, ortho- [SiO4]4−, di- [Si2O7]6 ...

EJM - Multistage origin of dunite in the Purang

Abstract. The Purang ophiolite, which crops out over an area of about 650 km 2 in the western Yarlung–Zangbo suture zone, consists chiefly of mantle peridotite, pyroxenite and gabbro. The mantle peridotite is comprised mainly harzburgite and minor dunite.

Measurement and Prediction of Thermal Conductivity

Accurate values of thermal properties of rocks are needed for a number of engineering applications starting from heat losses in buildings to underground geothermal modeling. Igneous rocks are one of the major constituents of the Earth’s crust and are formed by the crystallization and solidification of molten magma. In this work, the thermal transport properties of porous igneous basalt rocks ...
