 Cimmerian Orogeny

The Cimmerian Orogeny was an orogeny that created mountain ranges that now lie in Central Asia.The orogeny is believed to have begun 200–150 million years ago (much of the Jurassic Period), when the Cimmerian plate collided with the southern coast of Kazakhstania and North and South China, closing the ancient Paleo-Tethys Ocean between them.
