The extracted heavy-mineral concentrates were sieved into four fractions: <0.1 mm, 0.1-0.25 mm, 0.25-0.5 mm, and >0.5 mm. Magnetic minerals from each fraction were separated using a very weak magnet. Since awaruite is more magnetic than magnetite, its proportion in the resulting concentrate was high.

Geoscienceworld. The origin of the Cambrian–Ordovician tectono-magmatic events affecting NE Gondwana and the adjacent peri-Gondwanan terranes (e.g., Himalaya, Lhasa, Southern Qiangtang, Baoshan, Tengchong, Sibumasu, Helmand, and Karakorum) is controversial.

The geological evolution of the Tianshan Range attests to a complex history of long-lived accretion and continental growth in the Paleozoic, a long period of peneplanation in the Mesozoic, and later phases of Meso-Cenozoic reactivation caused by accretionary and collisional events along the Eurasian margin [1-4].In contrast to the well …
