| 1 | Cumulate complex xenoliths in the Early Mesozoic in eastern Inner Mongolia显示文摘Mafic xenoliths occur in Mesozoic diorites from nine localities in eastern Inner Mongolia from the Da Hinggan Mrs. to Huabei craton. Their petrologic and geochemical features suggest that they are an intact suite of cumulate complex whose mineral assemblages contain typical patent mantle metasomatism minerals such as pargosite, phlogopite and apatite. Their REEs and trace element characteristics suggest a comagmatic relationship in these cumulates with different compositions. Isotopic dating of the xenoliths indicates that they are products of the mantle magmatic underplating in the Early Mesozoic (237—224 Ma), and they may provide direct evidence for the crust-mantle interaction and vertical accretion of continental crust under a background of the mantle upwelling in the Early Mesozoic in Huabei region. | Ji’an Shao Qingjun Han Luqiao Zhang Baolei Mu | 1999 | Chinese Science Bulletin1999，44，14： | 21 |
| 2 | Alkaline Intrusives at the East Foot of the Taihang-Da Hinggan Mountains:Chronology,Sr,Nd and Pb Isotopic Characteristics and Their Implications显示文摘Based on the Rb-Sr isochron dating results, this paper suggests that the alkaline intrusive belt at the east foot of the Taihang-Da Hinggan Mountains were formed between 135 and 122 Ma. And the alkaline intrusives in the north and south sections of this belt have entirely different Sr, Nd and Pb isotopic characteristics, i.e., all the rocks in the south section have positive εSr(t) and negative εNd(t) values and all those in the north have the opposite values. On the εSr(t) versus εNd(t) correlation diagram, the samples from the south are concentrated along the enriched mantle evolution trend lines and nearby, while those from the north fall along the depleted mantle trend lines and nearby. On the Pb isotope composition diagram, most of the samples from the south section fall on the mantle Pb evolution line and nearby, while those from the north lie between the Pb evolution lines of the mantle and the erogenic belt. The above-stated isotopic characteristics not only indicate that the source rocks | YAN Guohan XU Baoliang MU Baolei WANG Guanyu CHANG Zhaoshan CHEN Tingli ZHAO Yongchao WANG Xiaofang ZHANG Renhu QIAO Guangsheng CHU Zhuyin | 2000 | Acta Geologica Sinica(English Edition)2000，74，4： | 18 |
| 3 | A skarn-type lead-zinc deposit related to low ^(18)O magma显示文摘THE Baiyinnuo skarn-type lead-zinc deposit occurs within the Da Hinggan Mountains, in theBalinzuo County 360 km north of the Chifeng City, the Inner Mongolia Autonomous Region.Skarns minerals and relevant igneous rocks in the deposits are extremely depleted in 18O. Thephenomena are also found in other skarn-type lead-zinc deposits in the Baiyinnuo region andshould be further studied. | MU Baolei, SHAO Jian, WANG Guanyu, YAN Guohan and Al YongfuDepartment of Geology , Peking University, Beijing 100871, China | 1997 | Chinese Science Bulletin1997，42，19： | 1 |

| 6 | The Rb-Sr age and geological implication of alkaline syenitic complex from Liangtun-Kuangdonggou at Gaixian,eastern Liaoning Province显示文摘Liangtun-Kuangdonggou complex, 30 km southeast of Gaixian Town, Liaoning Province, is composed of aegirine-augite hornblende syenite, aegirine-augite syenite, hornblende syenite, pyroxene syenite and syeno-aegirinolite. Rb-Sr isotopic data to the complex are reported and used for discussion of chronology and geological implication. They show that the complex occurred in early Proterozoic and is a tectonic sign of extension setting. Moreover, the date indicates that the Liaohe Group, which is metamorphic wall rock of the complex, formed over 1 900 Ma ago. | Baoliang Xu Guohan Yan Baolei Mu Linkun Tan Zhongfu He Guangsheng Qiao Renhu Zhang | 1999 | Chinese Science Bulletin1999，44，8： | 0 |
