Geochemistry on smectites in sediment cores CRP-1 and CRP-2 from the Ross Sea, Antarctica ...
TEM (transmission electron microscopy) observations and microanalyses on smectite microparticles in the sediments of the CRP-2A core were carried out to determine their origin (authigenic or detrital) and the source rocks. Smectites are dioctahedral and are Fe-rich members of the nontronite-beidelli...
