Raman spectroscopy of garnet-group minerals
Autor: Li Dien, Peng Mingsheng, E. C. T. Chao, H. K. Mao
Publikováno v: Chinese Journal of Geochemistry. 13:176-183
The Raman spectra of the natural end members of the garnet-group minerals, which include pyrope, almandine and spessarite of Fe-Al garnet series and grossularite, andradite and uvarovite of Ca-Fe garnet series, have been studied. Measured Raman spect

Autor: Mark L. Rivers, J.M. Back, M.J. Reed, J.N. Grossman, Stephen R. Sutton, G.L. Cygan, J.A. Minkin, E. C. T. Chao, J.R. Chen
Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 75:576-581
The concentrations of rare earth elements (REEs) in specific mineral grains from the Bayan Obo ore deposit and synthetic high-silica glass samples have been measured by synchrotron X-ray fluorescence (SXRF) analysis using excitation of the REE K line

Host-rock controlled epigenetic, hydrothermal metasomatic origin of the Bayan Obo REEFe-Nb ore deposit, Inner Mongolia, P.R.C
Autor: J.M. Back, J.A. Minkin, Ren Yinchen, E. C. T. Chao
Publikováno v: Applied Geochemistry. 7:443-458
Bayan Obo, a complex rare earth element (REE) Fe Nb ore deposit, located in Inner Mongolia, P.R.C. is the world's largest known REE deposit. The deposit is chiefly in a marble unit (H8), but extends into an overlying unit of black shale, slate and sc

The uses of synchrotron radiation sources for elemental and chemical microanalysis
Autor: E. C. T. Chao, Mark L. Rivers, J.M. Back, J.A. Minkin, J.R. Chen, Stephen R. Sutton, Keith W. Jones
Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 49:533-543
Synchrotron radiation sources offer important features for the analysis of a material. Among these features is the ability to determine both the elemental composition of the material and the chemical state of its elements. For microscopic analysis sy

THREE SYNTHETIC LUNAR GLASSES*
Autor: E. C. T. Chao, J. A. Minkin, D. R. Norton, R. P. Christian, E. E. Harris
Publikováno v: Meteoritics. 11:167-171
Glasses have been synthesized that have the approximate compositions of lunar rocks 61156, 68415, and 77135, respectively. The glasses have been analyzed by conventional analytical and electron microprobe techniques and have been found to be highly h
