摘要
辽西地区分布有巨厚的碳酸盐建造,其与中生代中酸性岩浆岩体相互接触形成了较多的夕卡岩铁矿.该类型矿床多产于辽西台陷与山海关台拱接触部位,与镁夕卡岩关系密切,多与铅、锌、钼等金属密切伴生.结合区域地球物理及地球化学资料,圈定大屯和钢屯偏道子为本区夕卡岩铁矿的成矿远景区.
Large-scaled carbonate formation is distributed in Western Liaoning Province. Along the contact zone of the carbonate formation and Mesozoic acid-intermediate magmatic rock bodies, occur lots of skarn-type iron ore deposits. Most of them, intimately related to Mg-skarn, form in the inter-terrestrial part between Western Liaoning syneclise and Shanhaiguan anteclise, coexisting with Pb, Zn, Mo etc. Combined with regional geophysical and geochemical data, the Datun and Piandongzi areas are regarded as advantageous prospecting targets.
