OGa. The 1863士44Ma U-Pb age of migmatite and 2071士48 Sm-Nd iso- chron age of amphibolite in Sanzhishu demonstrate that at least part of the "Hexi" Group is of Early Proterozoic rather than Late Paleozoic.
三枝树地区"鹤溪群"中混合岩年龄为1863±44Ma,斜长角闪岩全岩矿物Sm-Nd等时线年龄为2071±48Ma,表明景宁三枝树地区变质岩的时代应为早元古代,并非原来所属"鹤溪群"划归的晚古生代,这套变质岩可能是浙闽变质基底的一部分。
