| 1 | The Relationship between the “Green-Bean Rock” Layers and Conodont Chiosella timorensis and Implications on Defining the Early–Middle Triassic Boundary in the Nanpanjiang Basin, South China显示文摘The Triassic 'Green-bean Rock'(GBR) layers were widely recognized around the Early–Middle Triassic boundary interval in the Nanpanjiang Basin, South China. To determine the precise relationship between the GBR layers and the first appearance datum(FAD) of the conodont Chiosella timorensis, four Lower–Middle Triassic sections from the Nanpanjiang Basin, including the Gaimao, Bianyang II, Zuodeng and Wantou sections have been studied in detail. Detailed conodont biostratigraphy convinces us that there is no exact temporal relationship between the GBR layers and first occurrence of Ch. timorensis. Moreover, the numbers of the GBR layers are different from the place to place within the Nanpanjiang Basin, and the time span of the GBR layers was much longer than previously estimated. Global correlations show that the FAD of Ch. timorensis is contemporaneous basinwide and worldwide and more suitable marker defining the Olenekian-Anisian boundary(Early–Middle Triassic boundary) than any other proxies. | Chunbo Yan Haishui Jiang Xulong Lai Yadong Sun Bo Yang Lina Wang | 2015 | Journal of Earth Science2015,26,2: | 7 |
| 2 | Roadian-Wordian(Middle Permian)Conodont Biostratigraphy,Sedimentary Facies and Paleotemperature Evolution at the Shuixiakou Section,Xikou Area,Southeastern Qinling Region,China显示文摘Focusing on the Shuixiakou Section(Xikou area,Zhen’an County,Shaanxi Province,southeastern Qinling region,China),the Roadian-Wordian conodonts are investigated.More than 2000 conodont elements including 6 genera and 14 species have been obtained.Based on these materials,the Guadalupian Jinogondolella nankingensis and J.aserrata zones have been recognized.The Roadian-Wordian boundary is tentatively defined by the first occurrence of J.aserrata in the lower part of UnitⅢin the Shuixiakou Formation.The sedimentary succession of Xikou area records similar sea-level changes to those observed in Laibin area(South China).The 40 m-thick bioclastic limestone of UnitⅣin this section can be correlated with the reefs of Bed 114 in Laibin area.A temperature drop indicated byδ18Oapatite values suggests this Wordian interval coincides with a period of glaciation and global regression. | Baojin Wu Hanxiao Li Michael M.Joachimski Paul B.Wignall Haishui Jiang Lina Wang Xianlang Wu Xulong Lai Jiaxin Yan | 2021 | Journal of Earth Science2021,32,3: | 1 |

| 10 | Middle Triassic(Anisian)Conodont Biostratigraphy at the Shaiwa Section,Guizhou,South China显示文摘The Nanpanjiang Basin is a key area for paleontological and biostratigraphical study of the Middle Triassic.Herein we studied Middle Triassic conodonts from a well-exposed section,the Shaiwa Section,which is located at the northwest end of the Nanpanjiang Basin.A total of six Anisian conodont zones are recognized;in ascending order,they are:the Nicoraella germanica Zone,the Nicoraella kockeli Zone,the Paragondolella bulgarica Zone,the Neogondolella constricta Zone,the Neogondolella cornuta Zone,and the Paragondolella excelsa Zone,respectively.The first occurrence of Nicoraella kockeli defines the Bithynian-Pelsonian boundary.The Pelsonian-Illyrian boundary is defined by the first occurrence of Neogondolella constricta.The Anisian-Ladinian boundary cannot be recognized at the Shaiwa Section due to the absence of conodont indicative of the Ladinian.However,the new conodont data indicate that the uppermost strata could be very close to the boundary.The abrasion of conodont surfaces provides evidence for demonstrating reworking at the Shaiwa Section,which makes some conodonts possess a longer stratigraphic range than previously recorded.The variation in relative abundance between blade-shaped conodonts and platform conodonts indicates that segminiplanate elements probably preferred deeper and oxygenated environments whereas a restricted marine environment is more suitable for segminate elements. | Binxian Qin Martyn Lee Golding Haishui Jiang Yan Chen Muhui Zhang Li Kang Dacheng Wang Jinling Yuan | 2021 | Journal of Earth Science2021,32,3: | 0 |
| 11 | Personalized radioprotection in tumor patients after^(125)I seed brachytherapy显示文摘Objective:To investigate patient-specific radioprotection mathods for people in close contact with cancer patientstreated by 12I-seed implantation.Methods:The initial dose rates(D_(0))at distances of 30 and 100 cm from 80 patients who had undergone ^(125)I-seed implantation were measured within 24 h of the procedure.The dose rate at t(D_(t))and effective dose(E)were calculated according to the measurad vales of D.The appropriate precaution times for general adult family members,spouses,coworkers,and children or pregnant women were determined,and the relationships between and precaution time for different close-contact groups were derived by curve-fitting the corresponding data.Results:The mean D vahes of 80 patients at distanes of 30 and 100cm were(15.24±11.25)μSv/h and(1.96±2.63)μSv/h,respectively(P<0.05).The mean values and range of precaution time for general adult familymembers,spouses,coworkers,and children or pregnant women were(4.17±16.55),(102.93±49.22),(51.00±61.29),and(34.27±56.90)d(0-90.61),(0-234.01),(0-247.81),and(0-224.69)d,respectively.Furthemore,a logarithmic relationship betwen D and precaution time(Y)was observed for the different groujps.The equations of these relationships were detemined to be Y=-131.569+83.256 lnD_(0) for general adult family mambers,Y=—108.532+83.318 lnD_(0) for spouses,Y=25.470+83.318 lnD,for coworkers,and Y=2.585+83.229 lnD_(0) for children or pregnant women.Conchusions:Some cancer patients treated by ^(125)I-seed brachytherapy emitover-dose levels of γ-rays,necessitatingradiation protection for their close contacts.However,appropriate patient-specific radiation protection fordifferent close contacts can be determined based on the precaution time calculated using the D_(0) value. | Jianmin Li Liuyi Yang Haishui Xia Juan Wang Zhen Gao Aixia Sui Hongtao Zhang | 2021 | Radiation Medicine and Protection2021,2,3: | 0 |
