Uranium content and leachability of some igneous rocks and their geochemical significance
George J. Neuerburg, John C. Antweiler, Barrie H. Bieler
1956, Trace Elements Investigations 626
The uranium content and its leachability in 442 igneous rocks if wide variety were measured. Four-gram samples, crushed below 38 mesh, were leached in in 0.05 M HNO3 for half an hour at 80 to 85° C; the leachate and undissolved residue were analyzed fluorimetrically. This study explored the relation of...
Sub-glacial volcanic eruptions
Donald Edward White
1956, Trace Elements Memorandum 1089
The literature on sub-glacial volcanic eruptions and the related flood phenomena has been reviewed as a minor part of the larger problem of convective and conductive heat transfer from intrusive magma. (See Lovering, 1955, for a review of the extensive literature on this subject.) This summary of data on sub-glacial...
