禹城地区推覆构造的发现及意义

Discovery and significance of nappe structure in Yucheng area.

本文在研究禹城地区深部构造和区域构造应力背景的基础上,发现了禹城推覆构造,这一发现改变了对禹城地区构造特征的单一认识。文中认为,这种挤压褶皱是在印支压应力环境下发育、经多期构造应力叠加改造与加强形成的。这为该区的勘探指明了方向。

Based on the studies of deep structures and stress background of regional structure in Yucheng aera, the nappe structure in Yucheng area was discovered. The discovery changed the single understanding for structure characteristics in ths area. It is believed that the compaction fold was developed in the Indo-China compression stress environment, and was modified and enhanced after undergoing several rounds of structural stress. It is believed that the studies in this paper paves the way for the future exploration in this area.
