Potassium in ultramafic rocks

Geochimica et Cosmochimica Acta, 1953
Abstract Quantitative spectrochemical determinations of potassium in 50 specimens of ultramafic rock confirm the preliminary observation ( Ahrens , Pinson and Kearns , 1952) that the abundance of potassium in this rock type is much lower than has usually been assumed.

Lichens and ultramafic rocks: a review

The Lichenologist, 2004
Floristic, vegetational and ecological features of lichens in ultramafic environments are reviewed using a wide range of literature dating from the beginning of the 20th century. Co-presence of acidophytic (silicicolous) and basiphytic (calcicolous) species and the occurrence of species characterized by particular (disjunct) distribution patterns are ...

Ultramafic and Related Rocks

1972
The ultramafic rocks are composed mainly of dark-colored mafic or ferro-magnesian minerals such as olivine, pyroxene, amphibole, serpentine, garnet, biotite, and opaque oxides. They are usually, but not always, ultra-basic (having less than 45 percent SiO2).
