Rhythmic Layering of the Skaergaard Intrusion,series of the Skaergaard intrusion. The drill core of the hidden zone extends almost to the margin of the intrusion. This drill core therefore makes it possible to follow the initial formation of the layered series and the initial development of the rhythmic layering.

The Rhum Layered Complex, Inner Hebrides, Scotland,components are recognised: the Eastern Layered Series of alternating layers (up to 80m thick) of feldspathic perioditite and allivalite, totalling c. 600m in thickness; the Western Layered Series of layered gabbros conformably overlain by layered feldspathic peridotites; and a later intrusive Centra

,The Organization and Internal Structure of Cyclic Units in the Honningsvåg Intrusive Suite, North Nsm. Due to later orogenic events it is exposed in cross-section. The suite forms a lopolith consisting of 5 nested intrusions containing mainly olivine-chrome spinel (ocC), plagioclase — olivine (± chrome spinel) (pocC), plagioclase — Ca-rich pyroxene-olivine (paoC) and plagioclase — Ca-rich pyroxen

The Development of Compositional and Textural Layering in Archaean Komatiites and in Proterozoic Ko. Delayed nucleation and the compositional supersaturation caused by their high MgO contents are contributing factors. The development of equant olivine in the lower olivine cumulate zone is best explained either by continuous or en-masse settling of suspended olivine phenocrysts. Thicker flows cool
