Accurately locating boundaries between continental and oceanic crust is topical in view oflocating offshore boundaries relevant to margin formation models, plate kinematics, andfrontier resource exploration. Although we disagree with Tikku and Direen's interpretations, theassociated controversies reflect an absence of agreed-upon geophysical criteria for distinguishingstretched continental from oceanic crust, and a lack of samples from nonvolcanic margins.
