摘要/Abstract

摘要： 近年矿山深部找矿工作取得了一系列重要发现和进展. 重点介绍矿山深部找矿过程中具有代表性的新发现和新成果，包括：在内蒙古维拉斯托矿床深部发现具有大型规模的锡多金属矿体；在四川拉拉矿田深部的新层位发现了大型规模的红泥坡铜矿体；在西藏罗布莎铬铁矿深部发现与中央含矿构造岩相带有关的厚大铬铁矿体；在广东大宝山矿床深部发现斑岩型钼多金属矿体；在吉林夹皮沟金矿隐伏的石英闪长岩体顶部发现了细脉浸染型金矿体；在江西相山铀矿田深部发现铜铅锌多金属矿化. 这些新发现不仅加深了对已有矿床成因的理解，促进了深部成矿规律的认识，还为深部矿产资源勘查提供了重要依据．

Abstract: Continuous resource exploration of mines and adjacent areas has made important progress in recent years. This paper introduces new discoveries and achievements of deep ore exploration of representative mines，including Weilasituo，Lala，Luobusha，Dabaoshan，Jiapigou and Xiangshan deposits or ore fields. The large－scale Sn polymetallic orebodies were discovered in the Weilasituo deposit which used to be a Cu－Pb－Zn deposit. The Sn orebodies can be classified into three types，including disseminated orebody，vein－type orebody and breccia orebody，which were associated with granitic rocks in the deep of the deposit. The Cu orebodies in the Hongnipo deposit were developed in the Changchongyan Formation of Hekou Group. The Changchongyan Formation is a new Cu－bearing layer in the Lala orefield and shows huge prospecting potentiality for Cu. The Luobusha deposit located in Tibet is the biggest chromite deposit in China. The discovery of the Large－scale chromite orebodies associated with tectofacies zone is an important ore－prospecting breakthrough in Luobusha deposit. Porphyry polymetallic orebodies are found in the deep of the Dabaoshan deposit，which has changed the genesis of the deposit. Although the deposit type of the Jiapigou Au deposit is still controversial，the discovery of the veinlet－disseminated Au orebodies associated with quartz diorite in the deposit provides a good opportunity to address this issue. Due to the discovery of Cu and Pb－Zn polymetallic mineralization in the Xiangshan uranium ore field，the new deposit model of metal associations with U－Th in the upper，Pb－Zn－Au in the middle and Cu in the lower has been established. In summary，these discoveries and achievements are of great significance for promoting metallogenic studies and deep ore exploration in the future.
