| 中文摘要: |
| 贵州瓮(安)福(泉)磷矿(以下简称瓮福磷矿)展布范围约120 km2，按照一定密度在全矿区选取227个工程，通过编制矿层厚度和P2O5含量等值线图，综合分析了a、b两层磷矿层的分布和厚度、品位变化特征。a矿层主要分布在新桥矿段以北区域，在白岩背斜东翼北斗山南东侧和白岩背斜北倾伏端翁招坝、高白溪、转背岩围限区域形成两个大厚度区，厚度大于20 m。b矿层分布于瓮福磷矿区大部分区域，在白岩背斜北倾伏端西部翁招坝-高白溪一带形成大厚度区，厚度大于25 m。根据矿层延伸趋势、厚度变化和地质特征综合分析，白岩复背斜东翼延伸区域、北倾伏端北西方向延伸区域、大湾磷矿以西延伸区域具较好的找矿潜力。 |

| The spreading area of Wengfu phosphorite deposit is about 120 km 2 227 projects in this area are selected according to a density，by draw the seam thickness and P2O5 contour map，the distribution，thickness and change characteristics of a，b phosphorite seam are analyzed comprehensivelySeam a mainly distributed in the north Xinqiao section，in the south and east Beidou mountain of east Baiyan anticline and Wengzhaoba，Gaobaixi and Zhuanbeiyan area of north Baiyan anticline plunging crown，2 big thickness area formed which is more than 20 mSeam b distributed in the most area of Wengfu phosphorite mining area，the big thickness area which is more than 25 m formed in Wengzhaoba-Gaobaixi area of Baiyan anticline plunging crownBy analysis the seam extension tendency，thickness change and geological characteristics，it’s thought that the extended area of east Baiyan anticlinorium，north and west direction of north plunging crown and Dawan phosphorite mine has good prospection potential |
