Conventional energy resources are fast depleting and therefore alternative resources are required to sustain the fast progress and development of any nation. This situation is more pertinent to India where fast growing population and developmental activities are posing major challenges to the government as the country has limited resources of energy. Therefore, focused research should be intensified to explore the potential of geothermal energy resources in India. Realizing its importance, Wadia Institute of Himalayan Geology, Dehradun, has started a major research programme to study geothermal systems of the Himalaya covering Uttarakhand, Himachal Pradesh and Leh-Ladakh regions of India.Keywords

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

On 7 February 2021 at 10:30 am, a huge amount of slurry material flooded the Rishiganga catchment, resulting in excessive flow along the valley. The main cause of this flood was the dislocation of a huge rock mass approximately 540 m wide and 720 m long from the main rock body, which slipped down towards the Raunthi Gadera valley floor, causing massive devastation in the areas such as Raini, Tapovan, and Vishnuprayag. This event was not expected and was the first event in history when a flash flood occurred in winter. In this study, we tried to answer two major questions which are not been explained so far that are related to this disaster. These questions are (i) why did this event occur in winters? (ii) where did so much debris and water come from?. This study clearly answers these questions based on field observationsKeywords
