Abstract：The Houxianyu boron ore-field,tectonically located in the west of Yingkou-Kuandian paleo-uplift,East Liaoning anteclise,North China platform,is an important component of the East Liaoning South Jilin boron belt.The ore-bearing serpentinized peridotite is covered by thick inverted amphibolitic migmatite.Based on the geologic information gained from drill holes and mining tunnels,a 3-D software Surfer8 is applied to draw up some isopleth maps of the B2O3 contents,thickness and floor levels of ore-bearing beds for the boron deposits in the ore-field.Analysis shows that the ore-bearing beds in the boron ore-field are distributed zonationally and sectionally.The thickness is changed with directions.The ore bodies are controlled by the structural axes.Genesis study suggests that the boron deposits be formed by submarine volcanic eruption,when the ore-forming materials deposited along the crater in bands.Then regional metamorphism and compression made the ore-bearing beds distributed at the axes of synform or antiform.
