Coverage:	LATITUDE: 63.180000 * LONGITUDE: 23.600000
Event(s):	n5747 (Karnaite impact melt rock, Lappajarvi) * LATITUDE: 63.180000 * LONGITUDE: 23.600000 * LOCATION: Finland * METHOD/DEVICE: Rock sample (ROCK)
Comment:	* Discordance here refers to the calculated difference between the ²⁰⁶Pb/²³⁸U age and the ²⁰⁷Pb/²³⁵U age, i.e., discordance = (1 - [²⁰⁶Pb/²³⁸U age / ²⁰⁷Pb/²³⁵U age]) x 100. Therefore, positive numbers correspond to normal discordance and negative numbers correspond to reverse discordance.
	** % of common ²⁰⁶Pb in measured ²⁰⁶Pb, estimated from measured ²⁰⁴Pb, assuming present-day Stacey and Kramers (1975) common Pb. Figures lagged with # indicate that no correction has been applied because ²⁰⁴Pb counts were insignificant.
