Abstract
A large variety of objects in chondritic meteorites formed as a result of impact melting: shock veins, metal‐troilite mixtures, metal and sulfide nodules, melt pockets, vugs, agglutinates, glassy and crystalline spherules, and numerous types of melt‐rock clasts. The type of object produced in an impact event is related to the interaction of the shock waves with the particular target rock. Impact melting has also affected large portions of several chondrite breccias; many of these contain vugs and patches of silicate glass. Some workers have suggested that various iron meteorites (including groups IAB, IIICD, and IIE as well as several ungrouped irons) were formed from individual impact melt pools in chondritic regoliths. The Eagle Station Trio pallasites and several ungrouped meteorites (Bencubbin, Weatherford, Enon, Acapulco and Allan Hills A77081) may have formed from impact‐melted chondritic material. It is also possible that the parent magmas of ureilites were derived from impact‐melted metal‐rich carbonaceous chondrite material.
