Indeed, the Grand Canal was constructed partly utilizing the pre-existing channels connecting these lowland swamps and lakes (3) Several rivers have produced deltaic forms on the western side of the lakes;(4) A series of artificial islands have been constructed upon the natural bars or barriers located in the lakes and wetlands, and are locally termed Duo, Dun or Wei (meaning artificial bars or crossways in Chinese).

钻孔B/M界线之下(4078 m～4530 m)的泛滥平原河湖相沉积物中局部地段富含铁锰鲕粒，其主要矿物组成为蛋白石、铁的氢氧化物(包括纤铁矿、水纤铁矿、针铁矿、水针铁矿，统称褐铁矿)、铁锰氧化物(包括硬锰矿和软锰矿，以硬锰矿为主)及极少量的细小碎屑矿物(钾长石、蚀变黑云母、含铁白云母、锆石、独居石、金红石和含钛磁铁矿)。

In this paper, we report our structure observation and U-Pb zircon ages of the two types of Triassic granites, and use these data to place chronological constraints on the tectonic evolution of the western Kunlun orogenic belt. The gneissic garnet-bearing granite was crystallized at 241 Ma, whereas the horblende-bearing granite emplaced at 228 Ma.

对西昆仑西段海西晚期两类构造特征完全不同的花岗岩露头尺度的观察、锆石U-Pb定年结果表明，一类含石榴子石片麻状花岗岩形成时代为240.5±1.8 Ma，表现出同造山过程中的花岗岩变形特征；另一类块状含角闪石花岗岩的年龄为228.2±1.5 Ma。

The U-Pb and Pb-Pb isotopic dating of zircons provided the ages of 447-462Ma representing the ages of peak granulitic metamorphism. The U-Pb dating of detrital zircons from aluminum-rich gneisses yielded older upper intercept ages which reflect the times of older materials derived from sourse rocks of the gneiss protoliths.
