The Indian Plate collision with Eurasian Plate Week 5 - Derek Bryant


Hello Class,
I travelled to the Indian Plate, south of the Eurasian plate, this plate has taken roughly 40 to 50 million years to form the Himalayan mountain range. This plate is located in between India, and China with Nepal in the middle. The Indian plate use to be about 7000 km away from the Asian continent. Every century the Indian continent moved 9 meters until it finally collided with Asia. This began from 200 million years ago when the super continent Pangea began breaking apart and transformed into the lands we see today. When both collided, it created the famous mountain range we know today the Himalayans. The formations from the tectonic plates was based from compression, this type of tectonic plate conversion causes the rocks to be presses together. The rocks at the top will begin to push up and up bring mountain ranges. Rocks that are in the depths of the plates will compress and fold to either anticline or syncline. For this conversion the plates have made an anticline fold, the Himalayan mountains were created through the up folding where the fold goes upward. The syncline folds on the Indian and Eurasian plate created valleys in between the ranges. Overall, folding dominates the structural style of this conversion. The faults are in a reverse which creates the compression of the rocks. The rock being deposited here is sandstone.
