Allen C, Albert F, Chafetz H, Combie J, Graham C, Kieft T, et al.
Icarus . 2001 Sep; 147(1):49-67. PMID: 11543582
Physical evidence of life (physical biomarkers) from the deposits of carbonate hot springs were documented at the scale of microorganisms--submillimeter to submicrometer. The four moderate-temperature (57 to 72 degrees C),...

Thomas-Keprta K, Bazylinski D, Kirschvink J, Clemett S, McKay D, Wentworth S, et al.
Geochim Cosmochim Acta . 2001 Sep; 64(23):4049-81. PMID: 11543573
Using transmission electron microscopy (TEM), we have analyzed magnetite (Fe3O4) crystals acid-extracted from carbonate globules in Martian meteorite ALH84001. We studied 594 magnetites from ALH84001 and grouped them into three...

Rao M, Borg L, McKay D, Wentworth S
Geophys Res Lett . 2001 Sep; 26(21):3265-8. PMID: 11543347
Chemical compositions of impact melt glass veins, called Lithology C (Lith C) in Martian meteorite EET79001 were determined by electron microprobe analysis. A large enrichment of S, and significant enrichments...

Steele A, Goddard D, Stapleton D, Toporski J, Peters V, Bassinger V, et al.
Meteorit Planet Sci . 2001 Sep; 35(2):237-41. PMID: 11542972
Examination of fracture surfaces near the fusion crust of the martian meteorite Allan Hills (ALH) 84001 have been conducted using scanning electron microscopy (SEM) and atomic force microscopy (AFM) and...

Thomas-Keprta K, McKay D, Wentworth S, Stevens T, Taunton A, Allen C, et al.
Geology . 2001 Sep; 26(11):1031-4. PMID: 11541429
To explore the formation and preservation of biogenic features in igneous rocks, we have examined the organisms in experimental basaltic microcosms using scanning and transmission electron microscopy. Four types of...

Proc Natl Acad Sci U S A . 2001 Feb; 98(5):2164-9. PMID: 11226210
McKay et al. [(1996) Science 273, 924-930] suggested that carbonate globules in the meteorite ALH84001 contained the fossil remains of Martian microbes. We have characterized a subpopulation of magnetite (Fe(3)O(4))...
