Geochemical discrimination and petrogenetic affinities of dykes intruding the Ladakh batholith, NW India

Hybridization of granitic magmas in the source: The origin of the Karakoram Batholith, Ladakh, NW India

Mafic Dykes of Moyar Shear Zone, North Kerala, India: Emplacement History and Petrogenetic interpretation based on Structure, Geochemistry and Magnetic Fabric

Cretaceous mafic dykes in the Moyar Shear Zone (MSZ) area, north Kerala, India, provide signatures to probe into the nature of their source and thereby the evolution of the Mesozoic lithospheric mantle beneath the South Indian Granulite Terrain (SIGT). Bulk of the dykes in northern parts of Kerala is broadly in spatial association with the shear system. Mafic dykes striking NE-SW, NWSE, NNW-SSE...

Climate Change over Leh ( Ladakh ) , India

Mountains over the world are considered as the indicators of climate change. The Himalayas is comprised of five ranges viz., Pir Panjal, Great Himalayas, Zanskar, Ladhak and Karakorum. Ladakh region lies in the northern most state of India, Jammu and Kashmir, in the Ladhak range. It has a unique cold-arid climate and lies immediately south of the Karakorum range. With scarce water resources, su...

Geology and geochemistry of skarn deposits in the northern part of Ahar batholith, East Azarbaijan, NW Iran

Principal Skarn deposits along the northern margin of the Ahar batholith from west to east include Mazraeh, Vine and Gowdoul skarn deposits. Among these skarn deposits, the Mazraeh Cu-Fe Skarn deposit is the most typical skarn deposit in the NW Iran. This skarn deposit is located 5 km. north of Mazraeh village and 20 km north of Ahar town. The origin and development of the skarn can be related ...

Growth and Deformation of the Ladakh Batholith, Northwest Himalayas: Implications for Timing of Continental Collision and Origin of Calc-Alkaline Batholiths.

The calc-alkaline Ladakh batholith (NW Himalayas) was dated to constrain the timing of continental collision and subsequent deformation. Batholith growth ended when collision disrupted subduction of the Tethyan oceanic lithosphere, and thus the youngest magmatic pulse indirectly dates the collision. Both U-Pb ages on zircons from three samples of the Ladakh batholith and K-Ar from one subvolcan...
