One of the writers' main aims has been to help to prepare the way for a new approach to problems in which the natural occurrence of forsteritic olivines is a vital factor. Variation in their shapes and textural relations in minor intrusions, lavas and melts is examined and the historical development of concepts of their growth and resorption, particularly in magmas, is traced. Particular attention is focused on the olivines of picritic, minor intrusions. It is concluded that in the… Expand
Dendritic Crystallization: A Single Process for all the Textures of Olivine in Basalts?
The olivine macrocrysts found in oceanites, picrites and magnesian basalts erupted at hotspot volcanoes are generally interpreted either as phenocrysts crystallized from the magma or as xenocrystsExpand
Quartz crystals in Toba rhyolites show textures symptomatic of rapid crystallization
Abstract Textural and chemical heterogeneities in igneous quartz crystals preserve unique records of silicic magma evolution, yet their origins and applications are controversial. To improve ourExpand
A developmental model of olivine morphology as a function of the cooling rate and the degree of undercooling
We performed dynamic crystallization experiments in the CMAS system at 1 atm to investigate the evolution of the morphology of forsterite crystals as a function of cooling rate and degree ofExpand

Chemistry of the Shiant Isles Main Sill, NW Scotland, and Wider Implications for the Petrogenesis of Mafic Sills
Major and trace element data for the Tertiary, Shiant Isles Main Sill, NW Scotland, are used to discuss its complex internal differentiation. Vertical sections through the sill exhibit sharp breaksExpand
West Greenland Glass in Picrite – Low-pressure Cotectic Differentiates or Independent Compositions ?
The title of Larsen & Pedersen (2009) speaks to the tug that picrites have on the petrological conscience, extant at least since O’Hara (1968), but perhaps even before (Drever & Johnston, 1957),Expand
Capture of Helium and Other Volatiles during the Growth of Olivine Phenocrysts in Picritic Basalts from the Juan Fernandez Islands
Olivine crystals in basalt contain helium that can be extracted for isotopic analysis. Helium-bearing olivine phenocrysts in picritic tholeiites from the Juan Fernandez Islands, SE Pacific,Expand
