Abstract: Yanlong bauxiet-under-coal exploration project is one of the first integrated exploration projects in Henan province,at present,good ore-prospecting results has achieved. Samples of major elements,trace elements and rare earth elements are collected systematically,combined with some related test data,geochemical characteristics of the orebodies in the directions of vertical,horizontal and vertical are analyzed in depth. The analysis results show that the orebody is mainly affected by karst landform and later weathering and leaching,which lead to the metallogenic conditions in the recessed areas of land to the sea is superior to the projection area.
