متن کاملDelivery of dark material to Vesta via carbonaceous chondritic impacts
NASA’s Dawn spacecraft observations of Asteroid (4) Vesta reveal a surface with the highest albedo and color variation of any asteroid we have observed so far. Terrains rich in low albedo dark material (DM) have been identified using Dawn Framing Camera (FC) 0.75 lm filter images in several geologic settings: associated with impact craters (in the ejecta blanket material and/or on the crater wa...
متن کاملPlatinum Group Elements Analysis of Impactites from the Icdp Chicxulub Drill Core Yax-1: Are There Traces of the Impactor?
Introduction: The nature of the Chicxulub impactor is still not fully understood. Attempts to identify the traces of the impactor from chemical analyses of impactites within the crater are extremely controversial. Ir analyses of samples from the Chicxulub-1 and Yucatan-6 drill cores lead to different results. Nuggets of platinum group elements (PGE) and Ir concentration of more than 1000pg/g we...
متن کاملA Non-magmatic Iron Meteorite as Impactor for the Rochechouart Crater
The Rochechouart impact crater in the French Massif Central, has a diameter of 20 25 km [1] and an age of 250 my [2]. The cater is deeply eroded, down to the crater floor. Impact melt outcrops can be found in different parts of the crater [3]. The type of impactor that produced Rochechouart crater is still not clear. The first proposal of an IIA iron asteroid was based on the abundance of some ...
متن کاملThe Physical Properties of Meteorites and Interplanetaery Dust Particles: Implications for the Properties of Stone Asteroids
Introduction: Most asteroids for which porosities have been inferred have porosities ranging from 20% to >50%, with a mean of ~30% porosity [1]. Porosity significantly affects the physical properties of rocks, including the strength, thermal conductivity, seismic velocity, and dielectric permeability. Some asteroids have high enough porosities to affect their internal structure, gravitational f...
