Asteroidal Water Within Fluid Inclusion-Bearing Halite in an H5 Chondrite, Monahans (1998)

Michael E. Zolensky, 1* Robert J. Bodnar, 2 Everett K. Gibson Jr., 1 Laurence E. Nyquist, 1 Young Reese, 3 Chi-Yu Shih, 3 Henry Wiesmann 3

Crystals of halite and sylvite within the Monahans (1998) H5 chondrite contain aqueous fluid inclusions. The fluids are dominantly sodium chloride-potassium chloride brines, but they also contain divalent cations such as iron, magnesium, or calcium. Two possible origins for the brines are indigenous fluids flowing within the asteroid and exogenous fluids delivered into the asteroid surface from a salt-containing icy object.
