Genesis of collision volcanism in Eastern Anatolia, Turkey
Julian A. Pearce,John F. Bender,S. E. De Long,William S.F. Kidd,P.J. Low,Y. Güner,Fuat Şaroğlu,Yücel Yılmaz,S. Moorbath,J.G. Mitchell +9 more
TL;DR: In this article, it was shown that a large number of basaltic shield and fissure eruptions of transitional tholeiitic - alkaline composition were derived from the Arabia- Eurasia collision zone.

Volcano-stratigraphy and geochemistry of collision-related volcanism on the Erzurum–Kars Plateau, northeastern Turkey
TL;DR: A detailed study of the volcanic stratigraphy of the Erzurum-Kars plateau, together with new K-Ar ages and several hundred new major and trace-element analyses in order to evaluate the magmatic evolution of the plateau and its links to collision-related tectonic processes is presented in this paper.

Chronology of Neogene and Quaternary uplift and magmatism in the Caucasus: constraints from K–Ar dating of volcanism in Armenia
J.G. Mitchell,Rob Westaway +1 more
TL;DR: In this paper, the ages of volcanism at three localities in Armenia were determined as 1.1, 0.8 and 0.5 Ma by K-Ar dating, and also suggest a ∼1.2 Ma timing for the Late Akchagyl transgression of the Caspian Sea, a key event in the regional stratigraphy when this water body reached its greatest extent.

On dating the magmatism of Maio, Cape Verde Islands
TL;DR: In this paper, the authors used K-Ar and40Ar/39Ar studies of Mesozoic ocean floor basalts and Tertiary plutonic and volcanic rocks from Maio, Cape Verde Islands, have been determined to elucidate the magmatic evolution of this ocean island.

KAr ages of clay-size concentrates from the mineralisation of the Pedroches Batholith, Spain, and evidence for Mesozoic hydrothermal activity associated with the break up of Pangaea
A.N. Halliday,J.G. Mitchell +1 more
TL;DR: In this article, the ages of 32 clay concentrates extracted from samples of ore, gangue and wallrock associated with mineralisation in the Pedroches Batholith lie in the range 119-285 Ma.
