Bengal silts link Himalayas’ birth to Asian monsoon

An Indian research team has discovered clues to geological upheavals such as the rise of the Himalayas and its link to the onset of Asian monsoon in the sediments of Bay of Bengal.

Monsoons eroded the Himalayas and blew dusts forming silts that rivers transported to the sea, building the seafloor sediments. By studying the rate and pattern of sediment deposition in the Bay of Bengal over millions of years, scientists from CSIR-National Institute of Oceanography (NIO) and Oil and Natural Gas Corporation Limited have found that the deposition increased in two phases — from 65 to 54 and 34 to 23 million years ago. read more
