| 摘 要： | 海南岛燕山期逆冲推覆构造有NE向有军营-红岭构造带、戈枕构造带。两构造带都倾向NW,具有由NW往SE向逆冲推覆的运动学特征。在生成时间上,戈枕构造带略早,而军营-红岭逆冲构造带略晚,属于后从式逆冲推覆构造体系。其生成与印支块体和亚洲板块的相互作用有关。该逆冲推覆构造的厘定,为深入研究海南岛燕山阶段构造环境转化及其控矿作用具有重要的地质意义。

| Abstract: | As Yanshanian thrust nappe structures,NE-trending Junying-Hongling tectonic zone and Gezhen tectonic zone distribute in Western Hainan Island.The two zones are both in NW inclination,which present the kinematic characters of NW tending to SE thrust nappe.Considering the time of generation,Gezhen tectonic zone formed earlier,while Junying-Hongling tectonic zone formed later that can be conluded as following-type thrust nappe structure.The generation of the two structural belts are both related to the interac... |
