英文摘要: Abstract(#br)The Daqingshan granites are located in a late Mesozoic tectono-magmatic belt at the northern margin of the North China Craton (NCC), and include the Deshengying, Xinisubei, Gulouban, and Kuisu plutons. Ion probe U–Pb zircon dating indicates that the granites were emplaced at 131±1, 140±4, 145±1, and 142±2Ma, respectively. All of the granites are alkali- and potassium-rich, with high SiO 2 (73.2–76.7wt.%), K 2 O (4.50–5.57wt.%), Na 2 O (3.60–4.93wt.%), and K 2 O/Na 2 O (0.99–1.49), and low Al 2 O 3 (12.3–14.5wt.%), CaO...
