Abstract

The Yanshanian neutral-acidic volcanic rocks are widely spread in the north-middle section of the Taihang Mt. The faulted basin in the Laiyuan county, Shenxianshan region, north section of the Taihang Mt is geologically considered as the thrust nappe of one stage tectono-magmatic event. This paper reported that the zircon SHRIMP U-Pb dating result for the andesitic breccia tuff in the Tiaojishan group is 131±2Ma, which constrains the forming age of the Tiaojishan group and the timing of NW extensional structure in the north section of the Taihang Mt. This study provided new information for the Mesozoic magmatic events in the Taihang Mt.
