| 1 | 米仓山—汉南隆起白垩纪以来的剥露作用:磷灰石(U-Th)/He年龄记录显示文摘对米仓山南江南郑剖面上的13个花岗岩类样品进行了磷灰石(U-Th)/He测年和剥露速率计算,分析过程综合考虑了样品冷却速率、晶体大小等因素对磷灰石(U-Th)/He封闭温度的影响和地形起伏、岩体热传导、热对流及放射性元素生热等因素对地温场的影响.研究表明,米仓山南部沉积变形区自~50 Ma以来发生快速剥露(剥露速率为~70 m/Ma),新生代以来的剥蚀量超过了3 km;中部光雾山杂岩体记录了~90 Ma时一次快速剥露事件(剥露速率>75 m/Ma);北部汉南隆起区~100Ma以前以快速剥露为特点,平均剥露速率>40 m/Ma,此后转为缓慢剥露.整个米仓山汉南隆起区在90~50 Ma基本处于缓慢剥露状态,平均剥露速率仅有10~25 m/Ma. | 常远 许长海 Peter W.Reiners 周祖翼 | 2010 | 地球物理学报2010，53，4： | 35 |
| 2 | 大别山造山带白垩纪热窿伸展作用——锆石(U-Th)/He年代学证据显示文摘对大别山造山带的岳西-罗田核部及其南北两翼的13个锆石样品的(U-Th)/He测年结果表明,各样品锆石(U-Th)/He年龄介于85~155Ma之间,核部He年龄为85~107Ma,两翼年龄介于114~155Ma之间,反映岳西-罗田穹隆实际上是一个核部比两翼要热得多的热穹隆,形成大别穹状核杂岩这一热伸展事件可能持续到85Ma左右,核部岩石自85Ma以来的剥露量要比两翼多1528.8m。 | 周祖翼 Peter W.Reiners 许长海 廖宗廷 杨凤丽 | 2002 | 自然科学进展2002，12，7： | 8 |
| 3 | Zircon (U-Th)/He thermochronological constraints on Cretaceous thermal extension of Dabieshan orogen显示文摘(U-Th)/He ages of 13 samples from Yuexi-Luotian core and its flanks in Dabieshan orogen fall in the range of 155~85 Ma. He ages for samples from the core range between 85~107 Ma, while those from the flanks range between 114~155 Ma. The result shows that the Yuexi-Luotian core was a thermal dome in Cretaceous with core temperature being much higher than those of the flanks. The thermal extension which resulted in the formation of Dabie core complex lasted until ca. 85 Ma. The magnitude of exhumation in the core is approximately 1528.8 m more than that in the flanks. | Peter W.REINERS | 2002 | Progress in Natural Science:Materials International2002，12，7： | 3 |

| 6 | Early Mesoproterozoic evolution of midcontinental Laurentia: Defining the geon 14 Baraboo orogeny显示文摘New geochronologic data from midcontinental Laurentia demonstrate that emplacement of the 1476-1470 Ma Wolf River granitic batholith was not an isolated igneous event,but was accompanied by regional metamorphism,deformation,and sedimentation.Evidence for such metamorphism and deformation is best seen in siliciclastic sedimentary rocks of the Baraboo Interval,which were deposited closely following the 1.65-1.63 Ga Mazatzal orogeny.In Baraboo Interval strata,muscovite parallel to slatey cleavage,in hydrothermal veins,in quartzite breccia,and in metamorphosed paleosol yielded ^(40)Ar/^(39)Ar plateau ages of 1493-1465 Ma.In addition,U-Th-total Pb dating of neoblastic overgrowths on detrital monazite gave an age of 1488±20 Ma,and recrystallized hematite in folded metapelite gave a mean U/Th-He age of 1411±39 Ma.Post-Baraboo,arkosic polymictic conglomerate,which contains detrital zircon with a minimum peak age of 1493 Ma,was intruded by a 1470 Ma granite porphyry at the northeastern margin of the Wolf River batholith.This episode of magmatism,regional deformation and metamorphism,and sedimentation,which is designated herein as the Baraboo orogeny,provides a midcontinental link between the Picuris orogeny to the southwest and the Pinware orogeny to the northeast,completing the extent of early Mesoproterozoic(Calymmian)orogenesis for 5000 km along the southern margin of Laurentia.This transcontinental orogen is unique among Precambrian orogenies for its great width(-1600 km),the predominance of ferroan granites derived from partial melting of lower continental crust,and the prevalence of regional high T-P metamorphism related to advective heating by granitic magmas emplaced in the middle to upper crust. | L.Gordon Medaris Jr Brad S.Singer Brian R.Jicha David H.Malone Joshua J.Schwartz Esther K.Stewart Amanda Van Lankvelt Michael L.Williams Peter W.Reiners | 2021 | Geoscience Frontiers2021，12，5： | 0 |
