Impact jetting as the origin of chondrules
WitrynaWhat Are Chondrules and Chondrites? Chondrules are rounded objects typically from 0.1 to 5 mm in diameter, with an average size of roughly 0.4mm. They are made primarily of olivine and pyroxene with the occasional bits of glass and other trace minerals. Based on radioactive dating of Al-26, which is fairly quick and so leads to low levels, we ... Witryna1 sie 2014 · The extreme pressures reached during jetting, a process by which material is squirted out from the contact point of two colliding objects, causes melting and vaporization at low impact velocities. Jetting is a major source of melting in shocked porous material, a potential source of tektites, a possible origin of chondrules, and …

WitrynaAbstract. We explore impact jetting as a mechanism to form chondrules and subsequent pebble accretion as a mechanism to generate parent bodies of … WitrynaChondrules are one of the most primitive elements that can serve as a fundamental clue to the origin of our solar system. We investigate a formation scenario of chondrules …
WitrynaThe origin of most chondrules (small, previously molten spherules inside meteorites) is shown to be impact jetting; chondrules form from the shock-melted material ejected … Witryna15 wrz 2024 · Impact jetting during planetesimal collisions is a process that ejects small amounts of highly shocked material during the earliest stages of an impact. Jetting …
WitrynaPaleomagnetic experiments on separated chondrules can potentially reveal the presence of remanent magnetization from the time of chondrule formation. The existence of such a magnetization places quantitative bounds on the frequency of interchondrule collisions, while the intensity of magnetization may be used to infer the strength of … Witryna11 lis 2015 · Chondrules are one of the most primitive elements that can serve as a fundamental clue as to the origin of our Solar system. We investigate a formation scenario of chondrules that involves planetesimal collisions and the resultant impact jetting. Planetesimal collisions are the main agent to regulate planetary accretion that …
Witryna18 cze 2015 · All four chondrules define a brief formation interval with a weighted mean age of 4562.49 ± 0.21 Myr, consistent with its origin from the vapor‐melt impact plume generated by colliding planetesimals. Formation in a debris disk mostly devoid of nebular gas and dust sets an upper limit for the solar protoplanetary disk lifetime at 4.8 ± 0.3 Myr.
