About the Cover: Spider Wall on the south face of Nuptse (the summit ridge
is at ~7650 m, and the wall is ~1700 m in height), showing a network of leucogranite dykes
in metasedimentary rocks of the Everest Series (centre)
above the Nuptse leucogranite, visible at the bottom left and
right. Leucogranites emplaced in the shallow crust are the end product of melting of the deep
crust in orogenic belts. The view is from Pokalde Peak in
the Khumbu Himalaya, Nepal. ImAge Courtesy of mICAh Jessup,
