摘要
文章通过对蓟县地区锰硼矿地质、地球化学等方面的研究,认为蓟县地区寻找锰硼矿方面:(1)1∶5万水系沉积物锰、硼元素地球化学异常中的前干涧异常区和东水厂异常区;(2)长城系高于庄组地层是寻找海相沉积型锰硼矿的有利地层,尤其是高于庄组含锰粉砂质白云岩、含锰粉砂泥质白云岩、含锰粉砂白云质页岩地层;(3)已发现矿床(点)附近,就矿找矿,也是寻找锰硼矿床的有利区域。
The study on geological and geochemical characteristics of Mn-B deposits in Jixian area suggests that in respect of surveying for Mn-B deposits：（1） Qianganjian and Dongshuichang abnormal regions in manganese、boron element geochemical anomalies of 1∶50000 stream sediment are favorable areas to find Mn-B deposits;（2） Changcheng system Gaoyuzhuang formation is a favorable stratum to find marine sedimentary Mn-B deposits,especially those strata contain manganiferous silty dolomite,manganiferous aleuritopelitic dolomite,or manganiferous silty dolomitic shale;（3） the neighborhood of known deposits（mineral occurrence） are also favorable areas to find Mn-B deposits.
