The Meteoritic Component in Impact Deposits
Author(s): Kyte, Frank T.
Abstract: This proposal requested support for a broad-based research program designed to understand the chemical and mineralogical record of accretion of extraterrestrial matter to the Earth. The primary goal of this research is to ...

Identification of Late Eocene Impact Deposits at ODP Site 1090
Author(s): Kyte, Frank T.
Abstract: Anomalous concentrations of Ir have been found in upper Eocene sediments from Ocean Drilling Program (ODP) Hole 1090B. Clear and dark-colored spherules that are believed to be microtektites and clinopyroxene- bearing ...

Tracers of the Extraterrestrial Component in Sediments and Inferences for Earth's Accretion History
Author(s): Kyte, Frank T.
Abstract: The study of extraterrestrial matter in sediments began with the discovery of cosmic spherules during the HMS Challenger Expedition (1873-1876), but has evolved into a multidisciplinary study of the chemical, physical, and ...

Data Report: A Search for Deposits of the Late Pliocene Impact of the Eltanin Asteroid in Rise Sediments from the Antarctic Peninsula, Site 1096
Author(s): Kyte, Frank T.
Abstract: Concentrations of Ir have been measured in 87 sediment samples from Ocean Drilling Program Site 1096 in search of evidence of fallout from the impact of the Eltanin asteroid, which occurred at 2.15 Ma, approx. 1300 km ...

Accretion rate of extraterrestrial matter: Iridium deposited over the last 70 million years
Author(s): Kyte, Frank T.
Abstract: In order to quantify the accretion rate of extraterrestrial matter during the Cenozoic, Ir concentrations were measured in a continuous series of 450 samples across most of the length of piston core LL44-GPC3. LL44-GPC3 is a ...

Primary Mineralogical and Chemical Characteristics of the Major K/T and Late Eocene Impact Deposits
Author(s): Kyte, Frank T.
Abstract: Three well-characterized, distal impact deposits at the WT boundary and in upper Eocene sediments serve as a baseline for understanding other proposed impact deposits. All contain abundant spherules, evidence of shock ...

Anomalous Iridium Enrichment at the Triassic-Jurassic Boundary, Blomidon Formation, Fundy Basin, Canada
Author(s): Kyte, Frank T.
Abstract: We present new analyses that confirm Ir enrichment (up to 0.31 ng/g) in close proximity to the palynological Triassic-Jurassic boundary in strata near the top of the Blomidon Formation at Partridge Island, Nova Scotia. High ...

Sedimentation Patterns of Meteoritic Ejecta in Eltanin Impact Deposits at Site PS58/281
Author(s): Kyte, Frank T.; Gersonde, Rainer; Kuhn, Gerhard
Abstract: Deposits of the late Pliocene (2.5 Ma) Eltanin impact are unique in the known geological record. It is the only known km-sized asteroid impact into a deep-ocean (5 km) basin, and the central portion of the impact region is ...

The Cretaceous/Paleogene Transition on the East Tasman Plateau, Southwestern Pacific
Author(s): Schellenberg, Stephen A.; Brinkhuis, Henk; Stickley, Catherine E.; Fuller, Michael; Kyte, Frank T.; Williams, Graham L.
Abstract: Ocean Drilling Program Leg 189 recovered a potentially complete shallow marine record of the Cretaceous-Paleogene boundary (KPB) at Site 1172 on the East Tasman Plateau. Here we present high-resolution (cm-scale) data from ...

Summary of Results from Analyses of Deposits of the Deep-Ocean Impact of the Eltanin Asteroid
Author(s): Kyte, Frank T.; Kuhn, Gerhard; Gersonde, Rainer
Abstract: Deposits of the late Pliocene (2.5 Ma) Eltanin impact are unique in the known geological record. The only known example of a km-sized asteroid to impact a deep-ocean (5 km) basin, is the most meterorite-rich locality known. ...
