摘    要:黔北铝土矿含矿岩系地层的厚度在某些地段具有局部加厚的特征,这一特征预示了铝土矿的成矿控制作用存在非正常沉积控制的某些因素。本文通过对道真县池家沟矿点古岩溶起伏剖面的研究,发现岩溶古地貌环境对该矿点铝土矿层的厚度控制明显,其表明在黔北地区铝土矿含矿岩系分布区,下伏地层为碳酸盐岩分布的地段,古岩溶地貌环境是铝土矿含矿岩系地层厚度变化的控制因素之一。

关 键 词:古岩溶起伏  铝土矿  控制作用  黔北

Abstract:In northem Guizhou, bauxite tends to become thicker in some areas, this characteristic feature indicates that as for the ore-forming control of bauxite there exist some controlling factors of abnormal sedimentation. In this study, the authors investigated the ancient karst section in the Chijiagou ore deposit, Daozhen County and discovered that the physiognomy of ancient karst controls the thickness of ore deposit apparently. This demonstrates that ancient karst physiognomy - underlying carbonate strata of bauxite distributed in some areas in northern Guizhou -- is one of the factors controlling the thickness of bauxite-hosted strata.
Keywords:ancient karst physiognomy  bauxite  controlling action  northern Guizhou
