The use of a wide variety of geochemical tracers such as major and trace elements, Hf and Nd isotopes (Chapter 2) and U-series disequilibria (Chapter 4) allows constraining the relative influence of physical source parameters and dynamic melting processes. Particularly U-series isotopes, which inform us on rates of mantle melting are a sensitive tool to map the lateral expression of the temperature anomaly beneath Iceland and to resolve variability in melt productivity as a result of source heterogeneity.     To determine the U-series disequilibria recorded by the Icelandic basalts a new technique was developed to chemically separate U, Th, Pa and Ra from a single basaltic aliquot (Chapter 3).    In the final part of this book (Chapter 5) the potential to measure in situ U-Th disequilibria in titanite by femto second LA-MC-ICPMS is investigated. The study aimed to spatially resolve variability in U-series in accessory minerals from Laacher See Volcano, Germany to constrain timescales of magma evolution within the crust.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659146008\"\u003e\u003ch3\u003eAn application to Iceland\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659146008","offer_id":39487758827613,"sku":"9783659146008","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/19f3a57f-ef77-48d5-8b39-af1072fc3ce3.jpg?v=1757653467","url":"https:\/\/shop.autorenwelt.de\/en\/products\/u-series-constraints-on-mantle-melting-and-magma-evolution-von-j-m-koornneef","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
