| Abstract: | Cambrian volcano rocks in DangjinshanQingshuigou area in western Qilian mountain developed in volcano rock group in Cambrian Lapeiquan group. Distribution characteristics of the volcano rock and petrological characteristics have been studied and divided into 3 types of volcano rock facies, such as eruption facies, sedimentary facies and effusive facies. Volcano eruption cycles have been studied as well. The formation evolution characteristics in Dangjinshan area has been revealed. It has a certain guiding significance for the comparison of volcanic rock areas and the recovery of volcanic mechanism. |
