Herd, and P.A. Hunt. [Ottawa] : Natural Resources Canada, c2017. 1 poster : ill. Geological Survey of Canada, scientific presentation ; 45 Caption title. "Presented at the 35th Lunar and Planetary Science Conference, The Woodlands, Texas. Date presented: March 2004." Includes bibliographical references. “A comparison of smelter-derived dust particles (RDK), and chondrules in primitive (LL3, L4) ordinary chondrites (RKH), indicates similar crystallization textures, as imaged in back-scattered-electron (BSE) and secondary-electron (SE) modes with a scanning-electron microscope (SEM). An energy-dispersive spectrometer (EDS) system on the SEM allowed qualitative identification of phases. The similarity of textures, first recognized by PAH, allows us to consider implications for the conditions of formation of the dust spherules and the chondrules. Here we compare a class 4 smelter-derived particle [1] from the Horne copper smelter, Rouyn-Noranda, Québec, Canada, and a chondrule from the Saratov (L4) chondrite"--Intro. gccst Minerals gccst Scientific research Herd, Richard K.
