We report here the occurrence of albitite in Nubra valley of Ladakh region in the Trans-Himalaya area within Indian Territory at 344446N and 77338E before Panamik (in the Wish Pond, local name of the area). The albitite has been characterized by petrography, mineral chemistry, X-ray diffraction and whole rock geochemistry (i.e. major, trace and rare earth elements (REE)). The albitite comprises 85-96% albite and amphibole, whereas apatite, zircon and ilmenite occur as accessory minerals. The textural relationship and geochemical data indicate its igneous origin. The albitite contains about 5-6 ppm U and Th which may possibly host U-REE mineralization.Keywords

A devastating earthquake (M 7.8) occurred in the central part of the Nepal Himalaya on 25 April 2015 at 06:11:26.27 (UTC). USGS reported the epicentre location at 28.147°N and 84.708°E, and focal depth 15 km. The earthquake strongly hit Nepal causing over 7500 deaths and widespread destruction. A historical temple of 19th century was reduced to ruins within a few seconds.Full Text
