Ablated tektite from the central Indian Ocean
(Meteoritical Society, Fayetteville, USA, 1996)A well-preserved ablated (button-shaped) tektite recovered from the surface sediments of the central Indian Ocean lacks flow ridges and has apparently undergone ablation of 6.9 to 7.9 mm. The lack of flow ridges and amount ... -
Australasian microtektites in a substrate: A new constraint on ferromanganese crust accumulation rates
(Elsevier, 1994)Microtektites belonging to the Australasian tektite strewn field are found in the substrate of a ferromanganese crust dredged from the Central Indian Basin. They are identified on their physical appearance, geographic ... -
Changes in abundance and nature of microimpact craters on the surfaces of Australasian microtektites with distance from the proposed source crater location
(Wiley-Blackwell, 2010)Over 4600 Australasian microtektites from 11 sediment cores along an N-S transect in the Central Indian Ocean have been investigated optically for microimpact features on their surfaces. Detailed scanning electron microscope ... -
Impact microcrater morphology on Australian microtektites
(Meteoritical Society, 2003)Scanning electron microscopy of 137 Australian microtekties and fragments from 4 sediments cores in the Central Indian Ocean reveals more than 2000 impact-generated features in the size range of 0.3 to 600 mu m. Three ... -
Micrometeorite flux on Earth during the last ~50,000 years
(American Geophysical Union, 2013)Flux of micrometeorites is estimated by using cosmic spherule counts from a seafloor area of 2.50 ms<sup>2</sup> from the Indian Ocean. The spherules are recovered from sediment samples in close-spaced locations from the ... -
New occurrences of Australasian microtektites in the Central Indian Basin
(Meteoritical Soc. Fayetteville, USA, 1994)Thirty-three microtektites have been recovered from four different sites in the Central Indian Basin. Based on their physical properties, geographical occurrence and chemical composition, they are identified as belonging ... -
Oxygen isotope systematics of chondrules in the Allende CV3 chondrite: High precision ion microprobe studies
(Elsevier, 2011)The oxygen three-isotope systematics of 36 chondrules from the Allende CV3 chondrite are reported using high precision secondary ion mass spectrometer (CAMECA IMS-1280). Twenty-six chondrules have shown internally homogenous ...
