1铁岭组钾质斑脱岩锆石SHRIMP U-Pb年代学研究及其地质意义显示文摘最近在冀北-辽西以碳酸盐岩为主的铁岭组内发现了钾质斑脱岩,并获得其锆石SHRIMP U-Pb年龄——(1437±21)Ma,这一进展将铁岭组的时代确定为中元古代早期盖层纪(Calymmian Period)末期.与此同时,还在同一剖面获得了铁岭组的上覆地层——下马岭组碳硅质页岩里钾质斑脱岩锆石SHRIMPU-Pb年龄——(1372±18)Ma,这与稍早前在北京西北及其附近地区所获得的定年结果(~1380Ma)是一致的.这在肯定了该地区下马岭组应归入中元古代中期延展纪(Ectasian Period)早期的同时,也表明以蓟县剖面为代表的燕山东部地区铁岭组-下马岭组等相关序列,可与北京西山及燕山西部进行良好对比.换言之,华北北部从高于庄组到铁岭组的巨厚碳酸盐岩序列都应视为中元古界盖层系沉积,而铁岭组与下马岭组之间的不整合面可作为中元古界盖层系与延展系之间的物理性分界标志;早先以该不整合面命名的'芹峪上升'(或'芹峪运动')应属于一个时限短暂的中元古代早期的区域抬升,不能再视为华北克拉通对新元古代罗迪尼亚超大陆聚合事件(~1.0Ga)的响应.苏文博 李怀坤 HUFF W D ETTENSOHN F R 张世红 周红英 万渝生 2010科学通报2010,55,22:88
2中-新元古界标准剖面蓟县系首获高精度年龄制约——蓟县剖面雾迷山组和铁岭组斑脱岩锆石SHRIMP U-Pb同位素定年研究显示文摘近期在蓟县中-新元古界标准剖面铁岭组和雾迷山组首次发现斑脱岩、并测得其锆石SHRIMP U-Pb同位素年龄为~1440Ma(1439±14Ma)和~1485Ma(1483±13Ma和1487±16Ma),这标志着这条传统的标准剖面上以碳酸盐岩为主体的蓟县系上部的两个重要组,从此也获得了直接的、高精度的锆石U-Pb同位素年龄约束。这是华北中-新元古界标准剖面蓟县系相关地层单位首次获得直接而精确的锆石U-Pb同位素年龄约束,也是在整个华北北缘燕山地区雾迷山组内部首次获得精确的直接定年。这一进展为闻名中外的天津蓟县剖面中-新元古界年代地层格架的正确厘定、以及今后继续作为华北该阶段的标准剖面,并与国内外其他地区相关地层的正确对比等,提供了新的、精确的年代学"锚点",因而具有重要的科学和实际意义。李怀坤 苏文博 周红英 相振群 田辉 杨立公 Warren D HUFF Frank R ETTENSOHN 2014岩石学报2014,30,10:68
3SHRIMP U-Pb dating for a K-bentonite bed in the Tieling Formation,North China显示文摘A SHRIMP U-Pb zircon age of 1437±21 Ma was obtained for a recently discovered K-bentonite bed in the Tieling Formation,situated northeast of Beijing at the boundary between Liaoning and Hebei provinces,on the northern margin of the North China Craton(NCC).The SHRIMP U-Pb age places Tieling Formation near the end of the Calymmian Period of the early Mesoproterozoic Era.In addition,a SHRIMP U-Pb zircon date of 1372±18 Ma was acquired for K-bentonite beds in the overlying,dark-shale-dominated Xiamaling Formation from the same location northeast of Beijing.This date assigns a similar Mid-Mesoproterozoic(Ectasian Period) age for the Xiamaling Formation,as have previously determined dates from other sections northwest of Beijing.These dates indicate that the Tieling and Xiamaling formations,as well as the related succession in the eastern part of the Yanshan Mountains,represented by the well-known Meso-to Neoproterozoic standard section in Jixian,can be correlated well with sections northwest of Beijing in the western part of the Yanshan Mountains.In other words,the boundary between the Calymmian and Ectasian periods in the northern parts of the NCC is marked by the unconformity between the Tieling and Xiamaling formations in the northern NCC.This boundary was previously ascribed to the 'Qinyu Orogeny' and thought to be of Grenville age.In this regard,the conventional 'Qinyu Orogeny' should now be regarded as a short-lived regional uplift during Early Mesoproterozoic time,rather than a result from the Grenvillian assembly of the NCC to the Rodinia Supercontinent(~1.0 Ga).SU WenBo LI HuaiKun HUFF W D ETTENSOHN F R ZHANG ShiHong ZHOU HongYing WAN YuSheng 2010Chinese Science Bulletin2010,55,29:30

5什那干群层凝灰岩夹层SHRIMP锆石U-Pb年代学研究及其意义显示文摘在内蒙古乌拉特前旗大佘太镇附近的什那干群“下岩组”中下部,第一次发现了层凝灰岩等火山沉积夹层,并对其中的层凝灰岩(NM-1191)开展了SHRIMP锆石U-Pb年代学研究,精确标定其喷发时间为1614±8 Ma。由此可以确认,什那干群整体上应属于国际古元古代固结纪(Statherian Period,1800~1600 Ma)末期-中元古代盖层纪(Calymmian Period,1600~1400 Ma)初期(相当于中国中元古代长城纪(1800~1600 Ma)末期-蓟县纪(1600~1400 Ma)初期)沉积。这一新的年代地层学归属的确定,显示什那干群与毗邻的渣尔泰山群及白云鄂博群(化德群)的相应层位,应属于“三群并立”、“同时异相”的沉积古地理格局;同时这也表明,该群基本可与华北克拉通北缘-中部的大红峪组-高于庄组对比,并与南缘洛峪口组-龙家园组大体相当。结合相关资料可进一步推知,位于鄂尔多斯西缘贺兰山-千里山一带的黄旗口组-王全口组及阿拉善南缘龙首山地区墩子沟群中下部(即第一、第二岩组),也应与什那干群的层位基本一致。这一广泛存在的对比关系很可能也说明,至少到中元古代盖层纪早期,阿拉善(阴山)地块仍隶属于华北克拉通的范畴,并与鄂尔多斯西缘、燕辽盆地-华北中部带及熊耳裂谷区等,共同拥有一个统一的“泛华北”陆表海。什那干群新的年代学约束及相关地层单元年代学等时框架的建立,为重新认知该阶段华北克拉通北缘沉积-构造古地理及其演化,探讨华北克拉通与哥伦比亚超大陆关系等重要命题,提供了关键的年代地层学约束。苏文博 李文国 李惠民 宋彪 狄永军 周红英 王惠 王健 Frank R Ettensohn Warren D Huff 2022华北地质2022,45,2:2
