HjeUe and Winsnes (1972) reported chemical analyses of basalt from several nunataks in VestfjeUa including one sample of olivine gabbro from Utpostane (Fig. 14.9). In addition, Juckes (1968, 1969) pnblished a chemical analysis of basalt from the VA Nunatak which may be Nunatak A in Fig. 14.10 according to Fig. 1 of Fumes and Mitchell (1978). Later workers (e.g., Fumes and Mitchell 1978 Fumes et al. 1987 Luttinen et al. 1998) published a large number of additional major-element and trace-elanent analyses from the nunataks of Vest ella, including Plogen and Basen (Peters et al. 1989 Luttinen and Siivola 1997 Luttinen etal. 1994,1998). 

The nunataks Plogen and Basen consist of basalt flows of the Kirwan Volcanics cut by basalt dikes that strike northeast. The flows are interbedded with minor layers of pluvial sediment and the total stratigraphic thickness of the flow and sediment layers is greater than 900 m on Plogen and greater than 300 m on Basen (Luttinen and Siivola 1997). 

Fig. 14.18 The flows and dikes on Plogen and Basen have tita-nium/yttrium (Ti/Y) ratios less than six which is characteristic of low-titanium basalts. The magnesium number of these rocks, deflned as the atomic (Mg/Mg-i-Fe +) ratio, varies widely from about 0.4 to 0.7 (Adapted from Luttinen and Siivola (1997))...

Fig. 14.19 The chemical types (CT) of flows and dikes on Plogen and Basen are defined in terms of concentration ratios of Ti/P vs. Ti/Zr (a) and Nb/Ta vs. Ti/Zr (b). The chemical compositions of CT-1 and CT-2 resemble certain basalt flows of the Karoo Group in southern Africa, whereas the CT-3 samples resemble the Kirwan Volcanics on the nunataks of southern Vestfjella. A fourth chemical type (CT-4) was later added by Luttinen et al. (1998) (Data and interpretation from Luttinen and Siivola (1997))...
