If the Strong Crust Leads, Will the Weak Crust Follow?

View northeast in the central Sierra El Mayor showing the detachment fault that separates heavily intruded, light-colored, lower- plate migmatites (center and right) from dark-colored middle plate metasedimentary rocks (left). Middle-plate country rocks were shortened east-west and vertically thickened by isoclinal folding at greenschist conditions, while lower-plate country rocks and melanosome were mildly elongated east-west and vertically shortened.

Contemporaneous deformation at different levels of the conti- ° 11 30'E M nchen nental crust can be strongly heterogeneous, resulting in disparate 100 km A ZürichZ rich Austroalpine bulk deformation patterns between crustal levels.

NEWEST RELEASES center sectionTreat —Treat Oct. GSA Today Yourself!Yourself! Noted essayist John McPhee has gathered four of his most popular geology articles (originally published in The New Yorker magazine) along with a new selection just for this volume, into a work of breadth and realism. His “research assistants” are eminent geologists in their own right such as Anita Harris, Karen Kleinsphen, Dave Love, Eldridge Moores, and Randy Van Schmus. McPhee and his assistants explore the geology of North America, from “Rising from the Plains” to Assembling California.” McPhee’s well-known style puts extensive scientific research into an eminently readable format. Perfect for a colleague (or as your own special treat). OPB001, 695 p., hardbound, 6" x 9" format, ISBN 0-374-10520-0, $35.00 (sorry, no additional discounts available on this special volume)
