The intervening z=0.7443 Mg II absorption system in the spectrum of Q1331+170 shows an unusual series of line pairs with Δ v 30 km/s. These lines could be explained as the shells of expanding superbubbles residing in the outer regions of a spiral galaxy visible in the optical image of the Q1331+170 field. Photoionization models discriminate the conditions which could give rise to the observed absorption in the cold shell of the superbubbles and constrain the properties of the superbubbles themselves. Kinematic models of compact groups and galaxy pairs produce profiles largely inconsistent with the observed Mg II spectrum. This project is supported by the NSF/REU program and by NASA/LTSA through grant NAG5-6399.
