متن کاملTHE AGE OF TISSINT: Sm-Nd & Rb-Sr ISOTOPE SYSTEMATICS OF A MARTIAN METEORITE FALL
Introduction: The recently acquired meteorite Tissint is the first recognized fall of a depleted shergottite. Other such shergottites were found in the hot deserts (e.g., NWA 1195, Dhofar 019, DAG 476) or in the Antarctic cold desert (e.g., QUE 94201, Y980459) and, in many cases, have disturbed isotopic systematics due to terrestrial contamination [1-4]. Tissint represents the freshest sample o...

متن کاملHigh molecular diversity of extraterrestrial organic matter in Murchison meteorite revealed 40 years after its fall.
Numerous descriptions of organic molecules present in the Murchison meteorite have improved our understanding of the early interstellar chemistry that operated at or just before the birth of our solar system. However, all molecular analyses were so far targeted toward selected classes of compounds with a particular emphasis on biologically active components in the context of prebiotic chemistry...
متن کاملThe fall, recovery, orbit, and composition of the Tagish Lake meteorite: a new type of carbonaceous chondrite.
The preatmospheric mass of the Tagish Lake meteoroid was about 200,000 kilograms. Its calculated orbit indicates affinity to the Apollo asteroids with a semimajor axis in the middle of the asteroid belt, consistent with a linkage to low-albedo C, D, and P type asteroids. The mineralogy, oxygen isotope, and bulk chemical composition of recovered samples of the Tagish Lake meteorite are intermedi...
