SHRIMP dating of volcanic rocks from Ningwu area and its geological implications

The SHRIMP U-Pb ages are reported for two volcanic rocks from the Longwangshan and the Dawangshan formations respectively, Ningwu area, Jiangsu Province. The Dawangshan formation (NB-01) is dated at (127 ± 3) Ma, and the Longwangshan formation (NL-01), (131 ± 4) Ma. Besides, a few Archean zircons ar...

Zusammenfassung:The SHRIMP U-Pb ages are reported for two volcanic rocks from the Longwangshan and the Dawangshan formations respectively, Ningwu area, Jiangsu Province. The Dawangshan formation (NB-01) is dated at (127 ± 3) Ma, and the Longwangshan formation (NL-01), (131 ± 4) Ma. Besides, a few Archean zircons are also found in the Longwangshan formation, which suggests a possible Archean basement in the region.
