辽宁省主要金矿化集中区特征及今后找矿工作建议

辽宁省位于华北地台北缘，其地质构造演化主要经历了地台基底形成（Ａｒ－Ｐｔ１）、盖层沉积（Ｐｔ２－Ｔ２）、地台活化（Ｔ３以后）三个阶段。按成矿物质来源、成矿环境、成矿作用、矿点矿化点空间分布规律及物化探异常特征，辽宁省可划分出朝阳县小塔子—北票迷力营子、义县红石砬子—刘龙台、葫芦岛市水泉、建昌县温杖子、凌源市柏杖子、阜新县地宫—建设、浑南、浑北、盖县猫岭、辽阳田家围子—凤城弟兄山及丹东市沿江等１２个金的主要矿化集中区。辽宁省今后的地质勘查工作应注意以下几点：（１）要更新找矿观念，注意寻找新类型和大型超大型矿床；（２）按区域成矿条件，选好找矿重点突破区；（３）精确地认识和了解已知矿床，坚持就矿找矿；（４）坚持“五统一”的部署原则，利用地质、地球物理及地球化学方法进行综合找矿。

CHARACTERISTICS OF THE MAJOR GOLD METALLOGENIC CONCERTRATION REGIONS IN LIAONING PROVINCE AND SOME SUGGESTION ON THE FUTURE GOLD EXPLORATION

Liaoning province is located on the northern borderland of North China Platform, which has mainly experienced three stages: the forming of platform basement(Ar-Pt 1),the depositing of cover (Pt 2-T 2),and the activizing of platform(after T 3). On the bases of characteristics on the source of metallogenic material, metallogenic environment, metallization, distribution regular of ore points and metallization points, geophysical and geochemical prospecting anomaly, Liaoning province can be divided into 12 major gold metallogenic concentration regions: Xiaotazi Dongwujiazi of Chaoyao county, Hongshilazi Liulongtai of Yixian county, Shuiquan of Huludao city, Wenzhangzi of Jianchang county, Baizhangzi of Lingyuan city, Digong Jianshe of Fuxin county, Hunnan, Hunbei, Maoling of Gaixian county,and Tianjiaweizi of Liaoyang Dixiongshan of Fengcheng. On the geological prospecting,it is suggested to renew sense of ore prospecting,especialy to pay more attention to prospecting new types of and large scale gold deposits; to correctly selecting key break through areas of ore prospecting; to find new deposits in and aroud known deposits; to prospect with comprehensive methods of geology, geophysics, and geochemistry.
