英文摘要新疆库鲁克塔格地区上元古界可分为五个沉积层序,由下到上分别对应于贝义西组、照壁山组、阿勒通沟组、特瑞爱肯组至水泉组和汉格尔乔克组。第1层序由贝义西组构成,发育由粗碎屑斜坡扇和低水位楔构成的低水位体系域,向上逐渐变为粉砂岩、泥岩的海进体系域,并以向上变粗的退积准层序的高水位体系域结束,反映陆缘发展初期海平面的升降变化。第2层序由照壁山组构成,底部为粗粒石英砂岩,向上变为细粒砂岩、页岩互层,上部出现厚约30m 的泥岩,顶部为紫红色砂岩,代表了由低水位经快速海进到高水位的变化过程,整体为水体较浅的滨浅海沉积环境。第3层序由阿勒通沟组构成,为冰成杂砾岩、砂岩、页岩组合,顶部出现厚2~3m 的白云岩,沉...; According to the study on outcrop sequence stratigraphy of the Neoproterozoic strata in Quruqtagh area, five depositional sequences are recognized. In ascending order, the sequences correspond to the Bayixi, Zhaobishan, Altungol, Tereeken to Shuiquan, and Hankalchough formations, respectively. The Bayisi Formation (Sql) contains the lowstand system tract (LST) consisted by slope fan (SF) with gritstones and lowstand wedge (LW), the transgressive system tract (TST) consisted by siltstones and mudstones, and the highstand system tract(HST) consisted by coarsening-upward parasequences, implying the relative changes of sea level during the early stage of continent margin. The Zhaobishan Formation (Sq2), composed by coarse-grained sandstones at the base then thin mudstones and followed by mauve sandstones upwards, suggests a forming processes of the system tract from LST, through fast transgression, to HST. The Altungol Formation (Sq3) contains a LST of diamictites, sandstones and mudstones and a TST composed by 2 similar to 3m dolomites at the top. The HST is absent. The sequence 4 (Sq4) is complete, which is consisted by the diamictites of the Terreken Formation (LST) then the cap carbonates (TST) above the diamictites and followed by the turbidites of the Zhamoketi Formation, the shales of the Yukkengol Formation and the carbonates of the Shuiquan Formation (HST). The Yukkengol Formation is considered as the condensed section (CS). The sequence 5 (Sq5) only includes LST and TST, composed by the diamictites and dolomites of Hankalchough Formation, respectively. Its upper boundary is the unconformity between the Hankalchough Formation and the Cambrian. The Neoproterozoic sequences in the study area are correlated with the south China and India Lesser Himalaya areas.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000249590500010&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 13; 07; 1645-1654; 23
