Regional tilt of the Mount Stuart batholith, Washington, determined using aluminum-in-hornblende barometry: implications for northward translation of Baja British Columbia: discussion and reply
Article Abstract:
Ague and Brandon's method of calculating the regional tilt of the Mount Stuart batholith lacks validity because of its inability to account for the complexity of the processes involved in the determination of the geological character of the area. The authors should have used more data sets and not just a single one to come up with their paleomagnetic conclusions. Nevertheless, their limited data at least show the potential of using the calculation of paleobarometric surfaces as a geological measurement tool.

Regional tilt of the Mount Stuart batholith, Washington, determined using aluminum-in-hornblende barometry: implications for northward translation of Baja British Columbia: discussion and reply
Article Abstract:
The use of aluminum-in-hornblende (AH) barometry to evaluate the tilt of the Mount Stuart batholith is feasible because of the positive correlation between the total aluminum content of hornblende and equilibration pressure. Critics dispute that the AH estimates would apply only if emplacement temperatures are procured for all existing samples and if differences in temperature range do not exceed 4 kbar.

Article Abstract:
Ague and Brandon's contention that the Mount Stuart batholith is tilted is not accurate because they omitted certain factors in their study. Foremost of these factors is temperature whose effect cannot be rightly gauged through mere barometric data obtained through Al-in-hornblende barometry. Furthermore, estimation methods used are insufficient as only 10 of 46 samples were subject to in-depth analysis.
