A new study published in Precambrian Research by Jawad Shabbir, a Ph.D. student at Peking University's School of Earth and Space Sciences under Professor Song Shuguang, addresses a critical yet poorly understood period in Earth history.

Focusing on the Yinshan Block within the North China Craton (NCC), the research challenges previous ambiguities by revealing two complete orogenic cycles driven by tectonic processes similar to those on modern Earth. ...read more read less
