The laser-probe ages are lower than the minimum ages measured on the populations of grains by the step-heating method.
Laser-probe analysis of hand-picked single grains gives ages in agreement with those of overlying and underlying lava flows previously dated by the conventional K-Ar method.
Because pumice flows of the Monts-Dore massif crop out over large areas, these new ages will be useful for establishing a precise stratigraphy of the European Plio-Quaternary.
Géodynamique, Faculté de Sciences de Nice, 06034 Nice cedex, France), AB(Laboratoire et U. With the Ar step-heating method, we were able to detect contamination of Quaternary K-feldspars by Hercynian K-feldspars as low as 0.25ℵ.

In the early hours one morning last September, Lu Lobello rose from his bed, switched on a light, and stared into the video camera on his computer. The light cast a yellow pall on Lobello’s unshaven face. Lobello couldn’t sleep, couldn’t stop thinking about his time in Iraq. Other times, Lobello would see a Mercedes—a blue or white one, especially—and he’d recall the bullet-riddled sedan in the Baghdad intersection, the dead man alongside it in the street, the elderly woman crying in broken English, “We are the peace people! ” He’d remember that the barrel of his machine gun was hot to the touch. Right: Lu Lobello, a former marine in the company that opened fire on the family.And so, at two-thirty that morning, eight years after he had sprayed bullets into cars filled with Iraqi civilians, Lobello turned on his video recorder.“It’s very hard for me to say this, Nora, but we met on April 8, 2003,’’ Lobello said.
