With the use of published data, we show that non-solar components of N [1] and He, Ne, Ar [2] can be attributable to the terrestrial atmospheric components; the observed data for these elements are well explained in terms of the mixing between the terrestrial components and solar components. We propose that the examination of these terrestrial components would serve as unique tracer of the early Earth evolution.
In the present Earth, there is little interaction between the SW and ionosphere constituents due to the shielding effect of the geomagnetic field (GMF). However, if the GMF is absent, the SW directly interacts with the ionosphere. Terada et al. [3] showed that substantial amount of terrestrial ions will be picked up from the ionosphere and can be transported to the Moon, if GMF were absent. Therefore, the existence of terrestrial atmospheric components in some lunar soils suggests that at the time when the terrestrial components were implanted in the lunar soils, GMF was absent. Hence, if we find that the majority of lunar soils older than a certain age were systematically endowed with a disproportionately large fraction of plausible terrestrial components, we may conclude that GMF did not exist before this age. Also, the close examination of terrestrial components in lunar soils may impose constraint on the relative elemental abundance and isotopic composition of light elements in the ancient terrestrial atmosphere.
Assuming that the non-solar components in lunar soils are terrestrial, we estimated the flux of the terrestrial components (hereafter Earth Wind or EW) from mixing diagrams between the SW and terrestrial components. The absolute value was scal to the 4He flux (= 6.3 x 106 ions/cm2s; [4]) in the SW measured at lunar surface. The ancient atmosphere must have been depleted in oxygen and the early Sun was likely to be more active. Taking account of these effects, Terada et al. [3] made a theoretical estimate of EW flux which would hit the Moon. In Table 1, we compared this theoretical estimate with the EW flux estimated from the non-solar components observed in lunar soils. From Table 1, we infer that N and 36Ar can be accounted for by terrestrial components transported from a putative non-magnetic Earth, but barely for Ne (about 10%). If SW flux in ancient time was more intense, Ne may also be accounted for by EW.
Ну и где там не подвергается сомнению наличие земного азота? Ткните плз пальцем. Смысл понятен?:

Перевод:
Используя опубликованные данные, мы показываем, что без солнечного компонентов N [1] и He, Ne, Ar[2]
могут быть связаны с земной составляющей атмосферы, наблюдаемые данные для этих элементы хорошо объясняется с точки зрения смешения между наземными компонентами и солнечными элементами.

Перевод:
Следовательно, если мы обнаружили, что большинство лунных грунтов старше определенного возраста, систематически наделены непропорционально большой долей
правдоподобно земных компонентов, мы можем заключить, что ГМП (геомагнитное поле) не существовало до этого возраста. Кроме того, тщательное изучение земных компонентов в лунных грунтах может наложить ограничение на относительное обилие изотопного состава легких элементов
в древней атмосфере Земли.
Все понятно? Земное происхождение
предполагается из схожего состава древней земной атмосферы. И не более.
