Lithium in tektites and impact glasses: Implications for sources, histories and large impacts

Original language description

Lithium (Li) abundances and isotope compositions were determined in a representative suite of tektites, impact-related glasses, a glass fragment embedded in the suevite from the Ries impact crater and sedimentary materials in order to test a possible susceptibility of Li to fractionation during hypervelocity impact events and to deconvolve links to their potential parental sources. The overall data show a large spread in Li abundance (4.7?58 ppm Li) and d7Li values (-3.2 to 26.0?) but individual groupshave distinctive Li compositions. Extreme shock pressures and the related extreme post-shock temperatures alone appear not to have any effect on the Li isotope systematics; therefore, useful information on parental lithologies and magmatic processes maybe retrieved from analyses of Martian and lunar meteorites. Moreover, lack of significant Li depletion in tektites provides further constraints on the loss of volatile and moderately volatile elements during the Moon-forming impact.
