Volatile‐Assisted Intrusion and Autometasomatism of Leucogranites in the Khumbu Himalaya, Nepal
The Journal of Geology, 1999 Abstract Leucogranite crops out in the upper Imja Khola, Khumbu Himalaya, Nepal, where it makes up approximately 50% of the exposed bedrock. Leucogranites and their associated aplite‐pegmatites typically intruded as concordant sills, millimeters‐ to kilometers‐wide.

Neoproterozoic Anatexis of 2.9 Ga Old Granitoids in the Goiás-Crixás Archean Block, Central Brazil: Evidence From New SHRIMP U-Pb Data and Sm-Nd Isotopes [PDF]
Geologia USP. Série Científica, 2003 The first SHRIMP U-Pb ages for granitoid rocks from the southern part of the Goiás-Crixás Archean Block (Caiçara andUvá complexes) are presented and discussed in combination with Sm-Nd isotopic data in order to elucidate the main aspectsof the geological
