河北省涞水县野三坡国家地质公园：地质遗迹的地质意义和4期节理的导控作用

野三坡国家地质公园位于太行山断隆与燕山“台褶带”的结合部，两构造单元以紫荆关大断裂为界。公园内地质遗迹丰富，其地质内涵是华北地质的精髓。发育4期宏大构造节理，分别与印支期华南板块、燕山期伊佐奈歧板块、华北期太平洋板块和喜马拉雅期印度板块的挤压有关。4期节理，特别是喜马拉雅期南北向“追踪张节理”，对园区构造地貌景观的形成起着关键作用。

Yesanpo National Geopark in Laishui County, Hebei Province: Significance of geological relics and controlling roles of four stages of structural joint.

The Yesanpo National Geopark is located in the junction between the Taihangshan fault uplift and the Yanshan platform fold belt. The two tectonic units are separated by the Zijingguan fault. In the park there are plenty of sites of geological importance, all of which are the quintessence of the geology of North China. There are 4 stages of grand structural joints. They are related to the compression from the Indosinian South China plate, Yanshanian Izanagi plate, North China-aged Pacific plate and Himalayan Indian plate. The four stages of structural joints, especially the N-S trending "trace tensional joints" played a leading role in controlling the structural geomorphology of the National Geopark region.
