    One main difference is that the SiO 2 contents, while high in relation to the MgO contents observed, are not as high as those reported in other studies which are typically > 53 wt% (e.g. Arndt.   Archaean komatiites are shown to originate in hot mantle plumes that entrained hydrous material from deep in the mantle. Komatiites are a rare type Cited by:

    Most Archean komatiites are moderately depleted in highly incompatible elements and have been interpreted to have formed by a high degree (%) partial melting of depleted mantle either through equilibrium melting (e.g., Herzberg and O’Hara, ; Sproule et al., ) or fractional melting (Arndt et al., ; Arndt, ).

    The distinctive spinifex texture is formed by skeletal, platy, or acicular crystals of olivine, orthopyroxene, or clinopyroxene, or their pseudomorphs in ultramafic and mafic lavas or silicate-rich furnace slag. In lavas, these crystals form a pattern on weathered surfaces which Australian geologists compared to the local desert grass Triodia spinifex (Fig. 1a). Downloads from ePrints over the past year.

Bennett, Gerald K. Czamanske, Nicholas T. Arndt. Investigation of the extreme conditions in which komatiites formed provides important evidence about the thermal and chemical evolution of the planet, and the nature of the Precambrian mantle.

This monograph, written by three experts with long experience in the field, presents a complete account of the characteristics of komatiites including. Euan Nisbet has written three single author books and edited several multi—author volumes. The Young Earth was a core text on Archaean geology.

Leaving Eden (CUP) is translated into German. There have also been Chinese translations of Leaving Eden and Arndt and Nisbet (eds) Komatiites. Komatiites are fascinating volcanic rocks.

They are among the most ancient lavas of the Earth following the Ga pillow basalts at Isua and they represent some of the oldest ultramafic magmatic rocks preserved in the Earth’s crust at Ga. This fact, linked to their particular features (high magnesium content, high melting temperatures, low dynamic viscosities, etc.), has attracted the Cited by: Comprehensive bibliography on komatiites [microform] / compiled by Pauline C.
