华北西部贺兰山-桌子山及周缘地区奥陶纪构造演化与沉积响应研究评述

 华北西部贺兰山-桌子山及其邻区奥陶纪构造亲缘性、洋陆格局、盆地原型、物源以及板块缝合带的存在与否和具体位置等基础地质问题，长期以来一直存在激烈争论。近年来，随着岩石地球化学、古地磁、锆石地球化学和年代学等新数据的大量积累，相继提出一些新证据和新假说，将上述科学问题的研究引向深入。梳理近年来一系列最新进展，重点对一些关键基础地质问题存在的学术争议进行了评述。

Ordovician tectonic evolution and sedimentary response in the Helanshan-Zhuozishan Mountains and the peripheral regions,western North China: A review

The early Paleozoic ocean-continent framework, the basin prototype and the tectonic setting of the Helanshan-Zhuozishan Mountains, the western North China Craton (NCC) and its tectonic affinity remain as controversial issues, and the hot topics in the international geological community. In recent years, with the accumulation of new data such as the petrogeochemistry, the paleomagnetism, the zircon geochemistry and the chronology, some new lines of evidence and hypotheses were put forward, raising these scientific problems to a new level, but without consensus yet being reached. This paper reviews a series of latest progresses, and comments on some crucial basic geological problems, and puts forward suggestions for future research focusing on scientific issues.
