Journal Article
Published: 01 December 1988
American Mineralogist (1988) 73 (11-12): 1449–1456.
...Michael F. Hochella; James R. Lindsay; Victor G. Mossotti; Carrick M. Eggleston Abstract The effects of ion bombardment on homogeneous samples of quartz, albite, calcite, and anhydrite have been studied with X-ray photoelectron spectroscopy ( xps ) in order to better understand the usefulness...
Journal Article
Published: 01 February 1996
American Mineralogist (1996) 81 (1-2): 261–264.
...S. Chaturvedi; R. Katz; J. Guevremont; M. A. A. Schoonen; D. R. Strongin Abstract This work reports X-ray photoelectron spectroscopy (XPS) and low-energy electron diffraction (LEED) results for an as-grown (100) surface of pyrite (FeS 2 ) cleaned by low-energy He + ion bombardment and thermal...

GSA Bulletin (1972) 83 (3): 847–852.
... spaced edge dislocations. The peridotite specimen was deformed in the regime where pencil glide parallel to [100] dominates flow in olivine, and areas selected from the petrographic section were thinned to electron transparency by low-angle ion bombardment. Planar arrays of parallel edge dislocations...
Journal Article
Published: 01 November 2015
Mineralogical Magazine (2015) 79 (6): 1455–1466.
...W. R. Bower; C. I. Pearce; G. T. R. Droop; J. F. W. Mosselmans; K. Geraki; R. A. D. Pattrick Abstract A detailed understanding of the response of mineral phases to the radiation fields experienced in a geological disposal facility (GDF) is currently poorly constrained. Prolongued ion irradiation...

Journal: AAPG Bulletin
Published: 01 January 1946
AAPG Bulletin (1946) 30 (1): 32–51.
...C. W. Sheppard; W. L. Whitehead ABSTRACT In the experiments described, four members of the saturated fatty acid series are bombarded by the alpha particles from radon and its active deposit. The energy from the radiation causes principally chemical reaction resulting in formation of carbon dioxide...

... comprehensive ion microprobe study of zircons from a transect through the differentiated Sudbury impact melt sheet (Ontario, Canada). The new zircon Ti results and corresponding fully overlap with those of the Hadean zircon population. Previous studies that measured Ti in impact melt sheet zircons did not find...

... sections of apatite on spectral intensities is significant and only prismatic sections should be used. Signal decrease associated with electron bombardment (electron beam aging) is exponential and appears drastic in the first hundred seconds but continues even after 15 minutes of beam bombardment. All...

... oxides that comprise the bulk of the Earth and many meteorites. However, a new frontier opened in the microstructural analysis of Earth materials once it was shown that most minerals could be thinned to electron transparency with acceptably low levels of radiation damage by ion bombardment at ~6 keV...
