JMDMT #2465 Microfossils of Cyanobacteria in Carbonaceous Meteorites

crust. It must have formed in a reducing environment, because it contains many tiny metal droplets. It is covered in one place with a thin rind of a similar, but metal-free glass; this may be the terrestrial fusion crust. The composition of these glass coatings is very close to the bulk composition of the sample. Chemistry: The chemical composition of QUE 94281,18 (Table 1) is similar to that of EET 87521,46 [1] and Y 793274 [2]. All these

JMDMT #2466 Microfossils of Cyanobacteria in Carbonaceous Meteorites

The James M. DuPont Meteorite Collection - basaltic meteorites are mixtures of low-Ti mare basalts, as found in Apollo 15, Apollo 17, and Luna 24 samples and highland material. QUE 94281,18 and Y 793274 [2] are regolith breccias with a small amount of a meteoritic component (3 ppb Ir). Compared to EET 87521,46, the new basaltic meteorite has a higher content of anorthosite, indicated by the lower Fe and Mg content and the higher Al, Ca, and Ba concentrations (Table 1). The REE patterns of ...

Jochum KP Schultz L. Weber HW Wanke H. Chemistry, Petrology, and Noble Gases of Basaltic Lunar Meteorite QUE94281 Several interior chips of 0.556 g of the newest lunar meteorite QUE 94281,18, a basaltic regolith breccia, were obtained for INAA, SSMS, and rare gas analysis. Also available for investigation was thin section QUE 94281,9. Petrology: Our thin section shows a breccia with (usually fine-grained basaltic) lithic and mineral clasts in a finer-grained matrix. Conspicuous are the ...
