摘要
重庆市东南部桑柘坪向斜、濯河坝向斜和铜西向斜区二叠系下统梁山组所赋铝土矿和软质Ⅲ级耐火粘土矿具有明显的分布特征,矿床主要形成于二叠纪早世。从矿点分布特征入手,通过对比地质背景差异,探讨了铝土矿分布与华力西期古侵蚀面的关系,提出找矿方向与泥盆系上统地层的分布范围有重要关联。
Permian - Lower Jurassic Liangshan formation of Shangtuoping, Zhuohe dam, Tongxi synclines of southeast of Chongqing have bauxite mines and grade of soft III refractory clay deposits presenting the obvious characteristics of distribution, these mines and deposits are mainly formed in early Permian. This paper starts from the distribution characteristics of the mine sites, by contrasting the geological background, discusses the relationship between the distribution of bauxite mine and Variscan ancient erosion surface, finally proposes the conclusion that there is an important association between the prospecting direction and the distribution ranges of Devonian formation.
