STUDIES OF PARTICLES FOR EXTRATERRESTRIAL ORIGIN. 3. ANALYSES OF DUST PARTICLES FROM POLAR ICE DEPOSITS

A total of 166 dust particles collected principally from Greenland and antarctic ice has been subjected to chemical analysis by the electron beam microanalyzer technique. Several have Ni/Fe ratios indicative of a meteoritic origin. The remainder are probably also primarily cosmic in origin. The rate...

Description
Summary:A total of 166 dust particles collected principally from Greenland and antarctic ice has been subjected to chemical analysis by the electron beam microanalyzer technique. Several have Ni/Fe ratios indicative of a meteoritic origin. The remainder are probably also primarily cosmic in origin. The rate of deposit of opaque spherules is found to be nearly, but not exactly, the same at all geographical locations sampled. (Author) No Foreign.
