Analysis on Fold Style and Mechanical Characteristics of Lingshan Island in Qingdao City in Shandong Province
The fold tectonics in Lingshan island is developed and the types show various forms.Its origin type is still debated.Through geological mapping,based on the observation,measurement and analysis of of fold structural elements in Lingshan island,the origin of the fold structures in Lingshan Island has been discussed.The consistency of the occurrence of the folding hub in Lingshan Island,the consistency of the principal stress direction reflected by conjugate joints and folding axial planes,the geometric relationship between large and small folds,and the obvious structural origin of axial plane cleavage,window edge structure,pudding structure and other planar and linear structures reflect that Lingshan island folds be-long to structural origin.Based on comprehensive regional data analysis,it is believed that the folding structure of Lingshan island is the result of compression tectonic stress field with the trend of NW—SE.It is a response to the subduction collision between the ancient Pacific plate and the Asian continental margin.
