Kimberlites, carbonatites and ultramafic, mafic and potassic lamprophyres have been
produced in West Greenland in recurrent events since the Archaean. Five distinct age …

Abstract The Chinese Tien Shan range is a Palaeozoic orogenic belt which contains two
collision zones. The older, southern collision accreted a north-facing passive continental …

Splitting or thinning of lithosphere above a mantle plume can result in voluminous melt
generation, leading to the formation of large igneous provinces, or LIPs. Examples of LIPs …

Widespread basic magmatism across much of the western United States in the late
Cenozoic followed the cessation of subduction along the Pacific coast. This volcanism …

The association of hotspots and flood basalts has long been recognized [eg, Morgan, 1971].
Fluid-dynamic models [eg, Griffiths, 1986; Griffiths and Campbell, 1990] have produced a …

AFRICAN lions live in complex social groups and show extensive cooperative behaviour1–

Extensional accretionary orogens form by creation and destruction of large arc/back arc
basin systems, generated by extension and sediment infilling during prolonged slab retreat …

The Rogart pluton is a typical example of high Ba–Sr granitic magmatism, emplaced in
northern Scotland towards the end of the Caledonian Orogeny. It consists of three granitoid …

Cenozoic volcanic rocks sampled during the 1989 Sino-French Kunlun geotraverse have
been analyzed to constrain the origin of widespread Tertiary to Neogene Tibetan basic …

The potassic igneous rock suite (with molar K 2 O/Na 2 O> 1) can be divided into an
“orogenic” subgroup that occur in subduction-related tectonic settings and an “anorogenic” …
