Mineral Carbonation in Ultramafic and Basaltic Rocks

2016
Carbon capture and storage in the form of mineral carbonation in ultramafic and basaltic rocks offers a geologically stable repository of anthropogenic CO2. This chapter provides fundamental, theoretical and applied concepts relevant to mineral carbonation in peridotite, serpentinite and basaltic rocks.

The origin of ultramafic and ultrabasic rocks

Tectonophysics, 1969
Ultramafic rocks are classified in terms of their field associations and tectonic environment. Eleven associations are distinguished, some with subdivisions. The major features of each association are described in turn, and it is emphasized that the variety of field and petrographic associations indicates that a variety of processes is involved in the ...

Chlorine and fluorine abundances in ultramafic rocks

Geochimica et Cosmochimica Acta, 1968
Abstract A total of 55 ultramafic rocks of various modes of occurrence has been analysed for chlorine and fluorine by a rapid spectrophotometric method. The different modes of occurrence seem to have different abundance levels of Cl and F, but this may be due to secondary effects.

Peridotites and other ultramafic rocks

Geology Today
Peridotites are a group within the category of ultramafic rocks. These are usually dark‐coloured rocks rich in magnesium, poor in silica and lacking feldspars. Earth's mantle, which makes up 83 percent by volume and 67 percent by weight of the planet, consists largely of peridotite, which, although relatively sparse at the surface, therefore, is Earth ...

Ultramafic inclusions in basaltic rocks from Hawaii

Contributions to Mineralogy and Petrology, 1966
Ultramafic inclusions and the enclosing basaltic rocks were collected from a number of localities in the Hawaiian Islands; these and other specimens were studied by standard petrographic techniques and with an electron microprobe. Emphasis was on determination of mineral assemblages, mineral compositions, and variations in composition.

Ultramafic Rocks from the Mid-Atlantic Ridge

Nature, 1968
ACCORDING to the ideas of Hess1 the backbone of active mid-oceanic ridges should consist of peridotites which originated in the Earth's mantle and were subsequently upthrusted into the crust along the axis of ridges, above the up welling limbs of mantle's thermal convection cells.
