Himalayas - Wikipedia
网页The Himalayan range is one of the youngest mountain ranges on the planet and consists mostly of uplifted sedimentary and metamorphic rock. According to the modern theory of plate tectonics , its formation is a result of a continental collision or orogeny along the convergent boundary ( Main Himalayan Thrust ) between the Indo-Australian Plate ...

HJ/66/9 Geologic Formation of the Himalaya
网页The Higher Himalaya, the backbone of the Himalayan mountains, is made up of 10-20 km-thick metamorphic rocks (schist and gneiss) and granites situated at altitudes of 3000 m to over 8000 m. These rocks are Proterozoic-Cambrian age (2,000-500 Ma) and belong to the continental crust of the Indian plate.
