Sorted by: Date Added To NTRS in Descending order Petrogenesis of melt rocks, Manicouagan impact structure, Quebec Author(s): Simonds, C. H.; Floran, R. J.; Mcgee, P. E.; Phinney, W. C.; Warner, J. L. Abstract: It is suggested, on the basis of previous theoretical studies of shock waves, that the Manicouagan melt formed in 1 or 2 s in a 5-km-radius hemisphere near the point of impact. The melt and the less shocked debris ... NASA Center: Johnson Space Center Publication Year: 1978 Added to NTRS: 2004-11-03 Accession Number: 78A41093; Document ID: 19780057184 Manicouagan impact melt, Quebec. II - Chemical interrelations with basement and formational processes Author(s): Grieve, R. A. F.; Floran, R. J. Abstract: The basement rocks of Manicouagan exhibit a wide compositional range (40-72 SiO2). Least squares mixing calculations indicate that the average composition of the Manicouagan melt sheet can be modeled for 9 major and 11 trace ... NASA Center: NASA (non Center Specific) Publication Year: 1978 Added to NTRS: 2004-11-03 Accession Number: 78A41092; Document ID: 19780057183 Morphology of the Manicouagan ring-structure, Quebec, and some comparisons with lunar basins and craters Author(s): Floran, R. J.; Dence, M. R. Abstract: No Abstract Available NASA Center: Johnson Space Center Publication Year: 1976 Added to NTRS: 2004-11-03 Accession Number: 77A34812; Document ID: 19770051960 The Chassigny meteorite - A cumulate dunite with hydrous amphibole-bearing melt inclusions Author(s): Floran, R. J.; Prinz, M.; Hlava, P. F.; Keil, K.; Nehru, C. E.; Hinthorne, J. R. Abstract: The Chassigny meteorite, an iron-rich dunite (Fo 68), is a moderately shocked olivine achondrite or chassignite with features indicative of a cumulate origin with some subsolidus annealing. The evidence that the meteorite ...

J.; Caulfield, J. B. D.; Harlow, G. E.; Prinz, M. Abstract: No Abstract Available NASA Center: NASA (non Center Specific) Publication Year: 1978 Added to NTRS: 2004-11-03 Accession Number: 79A39157; Document ID: 19790055144 Silicate petrography, classification, and origin of the mesosiderites - Review and new observations Author(s): Floran, R. J. Abstract: A classification of mesosiderites proposed by Powell (1971) is modified and expanded to include impact melts. A petrographic study of all 20 mesosiderites reveals that most contain a complex assemblage of mineral, lithic, ... NASA Center: NASA (non Center Specific) Publication Year: 1978 Added to NTRS: 2004-11-03 Accession Number: 79A39156; Document ID: 19790055143 Petrology, structure and origin of the Manicouagan melt sheet, Quebec, Canada - A preliminary report Author(s): Floran, R. J.; Phinney, W. C.; Warner, J. L.; Simonds, C. H.; Jahn, B. M.; Grieve, R. A. F.; Dence, M. R.; Rhodes, M. J.

J.; Simonds, C. H. Abstract: Rb-Sr isotopic data for mineral separates from a rock of the Manicouagan impact melt sheet define an isochron of age T = 214 or - 5 (2 sigma) m.y. which agrees with the K-Ar age of 210 or - 8 (2 sigma) calculated by Wolfe ... NASA Center: Johnson Space Center Publication Year: 1978 Added to NTRS: 2004-11-03 Accession Number: 78A41095; Document ID: 19780057186 Mineralogy, petrology, and trace element geochemistry of the Johnstown meteorite - A brecciated orthopyroxenite with siderophile and REE-rich components Author(s): Floran, R. J.; Prinz, M.; Hlava, P. F.; Keil, K.; Spettel, B.; Waenke, H. Abstract: The compositional and petrologic characteristics of the Johnstown meteorite show it to contain uncontaminated and unbrecciated orthopyroxenite clasts of cumulative origin that (1) must have undergone subsolidus ...

I - Stratigraphy, petrology, and chemistry Author(s): Floran, R. J.; Grieve, R. A. F.; Dence, M. R.; Phinney, W. C.; Warner, J. L.; Blanchard, D. P.; Simonds, C. H. Abstract: A sheet of clast-laden impact melt 230 m thick and 55 km in diameter forms an annular plateau surrounding an uplift of shocked anorthosite within the moderately eroded Manicouagan structure. Three gradational units of the ...
