中文摘要:
      陡山沱组含磷岩系在瓮福磷矿全区分布,露头带围绕着白岩复背斜核部呈环带状出露,往西、往北缓倾斜隐伏产出,往东陡倾斜隐伏产出。最小厚度505 m,最大厚度8842 m,平均厚3480 m。大致分为两个大厚度区、三个中厚度区、两个小厚度区,大厚度区位于北西部翁招坝、南东侧北斗山—铅厂—沙子冲一线两个区域。陡山沱早期,瓮福地区整体属台地浅滩潮坪环境,可分为北部台地浅滩、南部潮坪两大部分;陡山沱晚期,瓮福地区属台地边缘浅滩潮坪环境,整体展现为地势平缓开阔的海滩地貌景观。
英文摘要:
      Phosphorite bearing rock series of Doushantuo formation can be found in the whole Wengfu phosphorite deposit,the outcrop belt exposed around white rock anticlinorium core with girdle appearance,conceal occurred flat dipping in the west and north,steeply dipping in the eastThe smallest thickness is 5.05m,the biggest thickness is 88.42m ,the average thickness is 34.8mIt generally be divided into 2 big thickness area,3 medium thickness area and 2 small thickness area,the big thickness area located in northwest Wengzhaoba and southeast Beidoushan-Qianchang-Shazichong areaIn the early Doushantuo period,the whole Wengfu area belong to paltform shallow tidal environment,the north area is platfotm shallow and the south area is tidal flatIn the late Doushantuo period,Wengfu area belong to platform edge shallow tidal environment,show a gently and open beachgeomorphologic landscape.
