Age and provenance of Grenville supergroup rocks, Trans-Adirondack Basin, constrained by detrital zircons

Autor: D. Kratzmann, Bruce Selleck, William deLorraine, Jeffrey R. Chiarenzelli

Publikováno v: Geology. 43:183-186

Detrital zircons from quartzites constrain the timing of deposition, provenance, and basin evolution of the Grenville supergroup in the Adirondack Lowlands. Three samples from the stratigraphic succession yield maximum depositional ages of 1284 ± 16

Utility of Detrital Zircon Grains From Upper Amphibolite Facies Rocks of the Grenville Supergroup, Adirondack Lowlands, Northeastern United States

Autor: Jeffrey R. Chiarenzelli, D. Kratzmann, Bruce Selleck, William deLorraine, Marian V. Lupulescu

Detrital zircons in quartz-rich lithologies from the deformed and metamorphosed Mesoproterozoic Adirondack Lowlands in northern New York, part of the Grenville Province, have been used to document sediment provenance and basin evolution, and provide

Preparation and performance of transmission-mode GaAs photocathodes as sources for cold dc electron beams

Autor: Andreas Wolf, S. N. Kosolobov, Dirk Schwalm, Dmitri A. Orlov, S. Pastuszka, D. Kratzmann, A. S. Jaroshevich, M. Hoppe, A. S. Terekhov

Publikováno v: Journal of Applied Physics. 88:6788-6800

Photoemission from GaAs cathodes with negative electron affinity (NEA) is applied for producing electron beams with very low longitudinal and transverse velocity spread. GaAs transmission-mode cathodes were activated with Cs and either O2 or NF3 in a

The 1991 explosive eruptions of Hudson volcano in southern Chile produced 2.7 km3 (dense rock equivalent) of basalt and trachyandesite tephra during the period August 8-15. The initial basaltic phase (phase I, August 8-9) produced a maximum column he

Hudson volcano (Chile) is the southern most stratovolcano of the Andean Southern Volcanic Zone and has produced some of the largest Holocene eruptions in South America. There have been at least 12 recorded Holocene explosive events at Hudson, with th

Publikováno v: AIP Conference Proceedings.

The comparative study of (Cs,NF3) and (Cs,O2) activation procedures and the measurements of the vacuum level position versus activation layer thickness show that the activation layer for optimally activated GaAs photocathodes with QE of about 20–30

Erratum to Compositional variations and magma mixing in the 1991 eruptions of Hudson volcano, Chile

Autor: D. Kratzmann, Jose-Antonio Naranjo, Steven Carey, R. Scasso

Publikováno v: Bulletin of Volcanology. 71:477-477

The August 1991 eruptions of Hudson volcano produced ~2.7 km3 (dense rock equivalent, DRE) of basaltic to trachyandesitic pyroclastic deposits, making it one of the largest historical eruptions in South America. Phase 1 of the eruption (P1, April 8)
