Determination of impurities in ice-cores form the Jungfrau-Joch by neutron activation analysis
- 43 Downloads
An ice-core of 4 m length was drilled at the Jungfraujoch. It was divided into 18 sections and analyzed for solid and dissolved material by neutron activation analysis using nondestructive counting as well as chemical group separations. The solid material was identified as stone dust. Part of the dissolved material seems to originate from dissolved limestone, whereas many elements can not be accounted for by this hypothesis and must be due to atmospheric fallout.
