The Whole Rock Sm-Nd 'Age' For The 2825 Ma Ikkattoq Gneisses (Greenland) Is 800 Ma Too Young: Insights Into Archaean Ttg Petrogenesis, Clark R L Friend, Allen Phillip Nutman, Halfdan Baadsgaard, M John M Duke

The Ikkattoq gneisses of the Archaean gneiss complex in the Nuuk region, southern West Greenland, are the orthogneiss component within the amphibolite facies Tre Brodre terrane. They have mostly granodioritic compositions, with a small amount of quartz diorite. Sm-Nd isotopic data for a quartz diorite and five granodiorite Ikkattoq gneiss samples from within 5 km of the Ikkattoq (fjord) type locality yielded a regression with a slope equivalent to 2005 +/- 52 Ma (MSWD = 0.72). Regardless of the low MSWD, this cannot be the true age of the Ikkattoq gneisses, because all Ikkattoq gneisses yield U-Pb zircon dates of …

Mapping a collection

A collection is never fixed, and any identifiable collection is greater than the sum of its parts. As Susan Stewart comments: "while we can 'see' the entire collection, we cannot possibly 'see' each of its elements." (On Longing: Narratives of the Miniat ure, the Gigantic, the Souvenir, the Collection, Baltimore and London: John Hopkins University Press, 1984, p.152). The Otago Polytechnic School of Art collection database lists 836 items, but this is not a complete record. There are other works that have perhaps fallen t hrough crilcks, while some works listed in the database may even dispute …
