Description:
Common gases from inclusions in glass fragments and spherules of lunar surface material returned by the Luna 16 automatic station were investigated by the adsorption volumometric method. Inclusions from eight particles were analyzed. A gas mixture from the inclusions had two- (CO2 and H2), three- (CO2, H2 and N2 + inert gases), and (H2S, SO2, and NH3), H2,N2 + inert gases, and four component (H2S, SO2, and NH3), CO2, H2, and N2 + inert gases, compositions. Hydrogen in all analyses was 10 to 95 volume percent. Diffusional exchange with the terrestrial atmosphere was absent. An unexpectedly high density of gases in the vacuoles was obtained. The initial volume of the bubbles when the vacuoles were breached even rose 2.5 times and decreased in the limits of 2.3 to 54.5 times. Various possibilities for the formation in the lunar surface material of glass fragments and spherules are discussed.
