Recently, a nearly E-W-striking, over 10 km long albitite zone has been recognized for the first time in the Lower Silurian Meiziya Formation in a Lower Paleozoic lead-zinc ore deposit concentration area of the Xunyang basin, South Qinling. It shows a conformable contact and gradational relationships with the country rocks and has thick-bedded and massive, banded, brecciated structures and fine and very fine equigranular and intraclastic textures. It is chemically characterized by enrichment in SiO2, Al2O3 and Na2O and is rich in the trace elements Fe and Mn and poor in the trace elements Co, Ni and Cu. Its ∑REE, LREE and HREE are lower than those of the country rocks and exhibit pronounced Eu depletion.
最近,在南秦岭旬阳盆地下古生界铅锌矿集区内的志留系梅子垭组地层中首次识别出一条近东西方向延伸长达10余千米的钠长石沉积岩带,与地层整合产出,渐变过渡,厚层块状,条带状,角砾状构造,均粒微-细晶结构,内碎屑结构;其化学成分以富含SiO2,Al2O3及Na2O为特征,富Fe,Mn,贫Co,Ni,Cu等微量元素;该钠长石岩的∑REE,LREE,HREE均较围岩偏低,具明显Eu亏损的特征。

SHRIMP and LA-ICP-MS zircon U-Pb dating yielded some age data: the Longchahe porphyritic granite is (81.2±1.4)~(83.2±1.4) Ma, the porphyritic granite in Malage-Songshujia area is (82.8±1.7) Ma, the porphyritic granite in Laochang area is (83.3±1.6) Ma and the Baishachong equigranular granite is (77.4±2.5) Ma.
文章首次采用LA-ICP-MS和SHRIMP U-Pb方法对研究区内的花岗岩进行了精确定年,数据表明,不同类型的花岗岩同时或近于同时形成。龙岔河似斑状花岗岩主要形成于(82.0±0.3)~(83.2±1.4)Ma,马拉格-松树脚似斑状花岗岩形成于(82.8±1.7)Ma,老厂似斑状花岗岩形成于(83.3±1.6)Ma,白沙冲等粒花岗岩形成于(77.4±2.5)Ma,均集中形成于晚白垩世。
