base notes	DASHED -- 85% up in Visean in chart of Aretz 25Mar'19. Gap zone (LAD to FAD) that spans half of the Chesterian (mid-Renault to base Menard). Base set arbitrarily as 1/4th between Zone 9 and base of Serpukhovian (was base of Zone 11 originally, but could be offset to base of Fraileys = mid Zone 11), due to large number of cyclothems in Zone 10. [The placement of top of Visean is not settled. TSC uses base Tarussian =330.34 Ma vs older definition of base L. ziegleri CdontZ = 331Ma - event placemnt 0.85 on older definiton but 0.816 with newer definition.]				comp notes
