Rare Earth Element (REE) profiles of KREEP-rich lunar samples (compiled from various sources)
Summary edit
| Description |
English: Rare Earth Element (REE) profiles of KREEP-rich lunar samples 12013 and 15386. Generated from data of Neal & Kramer (2003),[1] Quick et al. (1977),[2] Schnetzler et al. (1970),[2] and Warren (1988).[2] REE fraction values are normalized against values obtained form chondrites (Anders & Grevesse, 1989).[3] Schnetzler et al. (1970) do not give values for Lanthanium and Hafnium, Quick et al. (1977) do not give values for Erbium. Profiles with general low values but raised content of Erbium and Ytterbium (some data of Schnetzler et al., 1970, and Quick et al., 1977) represent so-called high-K KREEP.
Deutsch: Seltenerdelement-(SEE)-Profile der KREEP-reichen Mondgesteinsproben 12013 und 15386. Erstellt aus Daten von Neal & Kramer (2003),[1] Quick et al. (1977),[2] Schnetzler et al. (1970),[2] und Warren (1988).[2] Die SEE-Werte sind gegen aus Chondriten ermittelte SEE-Werte (Anders & Grevesse 1989)[3] aufgerechnet (normalisiert). Schnetzler et al. (1970) geben keine Werte für Lanthan und Hafnium an, Quick et al. (1977) geben keine Werte für Erbium an. Profile mit generell niedrigen Werten jedoch erhöhtem Erbium- und Ytterbium-Gehalt (einige Daten von Schnetzler et al., 1970, und Quick et al., 1977) repräsentieren KREEP mit besonders hohem Kalium-Gehalt (sogenanntes „high-K KREEP“). |
