Many Chinese angiosperm elements are present in the modern flora of Northeast India especially in the Himalayan region. It appears that they migrated in the past from the nearby areas or from the bordering areas of China. In order to determine the nature of the paleomigration of these elements，it is necessary to know the fossil flora of the region before and after the joining of the Indian Plate with the Asian Plate.

The continuous northward movement of the Indian Plate during the Palaeogene ultimately led to its collision with the Asian Plate resulting in the formation of the Himalayas. This formation took place in three phases. The first phase of the collision between the Indian and Asian Plates took place during the Early Eocene along the northeastern corner of India. ......     （共10285字）    [阅读本文]>>
