Melville Bugt	MB1:MB2:MB4:MB5:MB7:MB9:QT:JP:OF	Region	Melville Bugt dyke swarm ca. 1630 Ma pole	a	g	LP-DIR-AF:LP-DIR-T:LP-DC4:DE-BFL:DE-FM:DE-VGP:GM-UPB-CC:FS-FD:SO-SM	10.1007/978-3-642-12496-9_27	Igneous	Diabase	69.2668	77.5933	293.1183	309.5521	Greenland	Greenland	1630	1619	1638	Ma	0	208.5	31.0	13.1	16.5	9	4.0	274.5	9.3	31.3	9	Site directions and U-Pb baddeleyite ages from Halls et al. (2011); pole calculated as Fisher mean of site VGPs. VGPs taken directly from Halls 2011 Table 27.1; paper convention: north poles given for SW-directed remanences, south poles for NE-directed ones. Age range reflects bracketing U-Pb dates; nominal pole age 1630 Ma (mean of the four dated pole dykes: OF 1622.1 +/- 3.2, MB2 1629.4 +/- 0.8, QT 1632.0 +/- 1.1, MB9 1635.0 +/- 2.7 Ma, all 2sigma; Halls et al., 2011); the location age bracket 1619-1638 Ma is the 2sigma envelope of those dates. A fifth dyke ~1000 km SE (Snehatten) is 1629.7 +/- 3.9 Ma (Klausen & Nilsson, 2019). Pole is the Fisher mean of the 9 dyke VGPs (k=31.3, A95=9.3); the OF chilled margin is the margin of the OF dyke and is not counted separately.
