Our results reveal apparent inconsistencies between AFT and AHe data: the AHe ages corrected for alpha ejection according to the standard procedure [Farley, K.
In order to test the relevance of alpha ejection correction, mechanical abrasion of several apatite grains was applied.
The heating event is interpreted in terms of burial of the basement beneath a several kilometres thick pile of Devonian and Carboniferous sedimentary deposits of the adjacent Dniepr-Donets Basin.
During Permo-Triassic times, large parts of the basement were affected by a thermal event related to mantle upwelling, associated magmatic activity and increased heat flow in the adjacent rift. (U-Th)/He dating: Techniques, calibrations, and applications.
The northern part of the basement and its sedimentary cover record a cooling event in the Jurassic, which was probably related to erosion. The effect of long alpha-stopping distances on (U-Th)/He ages.
However, although Ar-Ar data of Jurassic magmatic activity in the Donbas Foldbelt are about 20 My younger than the AFT data, thermal relaxation after elevated heat flow associated with this magmatic event cannot be completely ruled out.
Constant social interaction is not just an unavoidable subproduct of the ever-increasing urban co-habitation, it is also very much a prerequisite for our humanity in general and our own place in the surrounding society in particular.

Thus, his obsession with Jung becomes his own daily routine, a routine which he takes very seriously.
Every night at 4.30, woken up by his several alarm clocks, he conducts his nocturnal forays into Jung’s bedroom.
His own mind is grief-stricken by the loss of his girlfriend and he chooses to ignore even the boy’s unimpeded attempts at provoking a reaction from him.
In a rare moment of actual interaction between the two one night on the stairs, the only thing Jung can think of is to offer the 11-year-old a cigarette while tears are welling up in his eyes.
