Geochemical and Geochronological Constraints on Early Lunar
نویسنده
چکیده
Introduction: The aim of this abstract is to acquaint the reader with the major geochemical and geochronological properties of lunar rocks formed or affected by impact events, and thus how these rocks constrain lunar bombardment history, with particular emphasis on constraints upon the proposed Lunar Cataclysm or Late Heavy Bombardment [1]. To this end, the focus is on clast-poor impact melt rocks and crystalline melt breccias as products of large impacts (>1 km craters) and basins (>300 km craters) Though micrometeorite impacts and secondary craters are create agglutinitic glass and impact melt splashes, they are not considered here.

متن کاملThe Effects of Basin Formation on the Lunar Geochemical Terranes
Introduction: The early history of the Moon, namely the first ~700 My following its formation, was an era marked by the formation of 43 basins (impact craters >300 km in diameter) [1,2,3]. Basin formation during this period had significant effects on the entire lunar crust; material from depth was excavated and redistributed across the entire surface [4]. The material redistributed by basins ca...

Introduction: The preponderance of 3.9 Ga lunar impact-melt rock ages and the dearth of older samples of unequivocal impact origin, from either the Apollo collection or lunar meteorites, suggest an extraordinary bombardment event in the Earth-Moon system at ~3.9 Ga. We have begun to study another set of samples, impact melts and crystalline lunar spherules (CLS) within demonstrably old Apollo b...

متن کاملPSRD: Age Rules
The ages of rocks from the lunar highlands vary widely, even for a single rock sample. This makes it difficult to quantitatively test ideas for early lunar differentiation and formation of the crust. Lars Borg and Amy Gaffney (Lawrence Livermore National Laboratory), and Charles Shearer (University of New Mexico) have devised a set of guidelines to apply to geochronological data that leads to a...
