Its zircon U-Pb age is dated at (154~155) Ma. This granite pluton is characterized by enrichment in Li, Rb, Sn, W, Nb, Ta etc. rare metal elements, Pb, Zn etc.style="FONT-FAMILY: ’Times New Roman’,’serif’" lang=EN-US> style="FONT-FAMILY: ’Times New Roman’,’serif’; mso-fareast-font-family: DotumChe" lang=EN-US>base metal elements and H2O, F etc.style="FONT-FAMILY: ’Times New Roman’,’serif’" lang=EN-US> style="FONT-FAMILY: ’Times New Roman’,’serif’; mso-fareast-font-family: DotumChe" lang=EN-US>volatiles. A vertical zonation is well developed within a vertical distance of (450style="FONT-FAMILY: DotumChe; mso-ascii-font-family: ’Times New Roman’; mso-bidi-font-family: ’Times New Roman’">～style="FONT-FAMILY: ’Times New Roman’,’serif’; mso-fareast-font-family: DotumChe" lang=EN-US>500) m. From the deeper level upwards to the top of the Laiziling Mountains peak, the following zones are successively observed:style="FONT-FAMILY: ’Times New Roman’,’serif’" lang=EN-US> style="FONT-FAMILY: ’Times New Roman’,’serif’; mso-fareast-font-family: DotumChe" lang=EN-US>protolithionite granite zone, leucogranite zone, albite granite zone, greisen zone, massive quartz and pegmatoid stockscheider. The authors propose that the primary magma source of the Laiziling granite might be derived from the A-type Qitianling batholith, or a fractionated deeper magmatic chamber similar to the Qitianling granite.space prefix = o ns = "urn:schemas-microsoft-com:office:office" />
