Fifty-four new heat flow measurements in the central troughs of the Guaymas basin support the hypothesis that they are sites of active intrusion. In the N trough a distinct pattern of hydrothermal cooling is revealed, with venting along the W boundary fault of the trough. In the S trough an analogous pattern is apparently superimposed upon a conductive cooling anomaly associated with a recent central intrusion. The discharge of thermal waters occurs along the boundary faults and through other faults associated with a possible horst block located in the N central floor of the S trough. The heat flow patterns suggest that the intrusions are episodic and do not occur simultaneously along the length (15-40 km) of a spreading segment. A review of all available heat flow measurements of the Guaymas basin suggests that most of the recharge for a pervasive regional hydrothermal system is limited to the central depressions, with perhaps some contribution from pore water.- Authors
