| 中文摘要: |
| 代家庄铅锌矿是西秦岭泥盆系铅锌矿带近年来新发现的矿床,矿床类型是以白铅矿、菱锌矿为主的碳酸盐型,是区内有别于硫化物型的一种新类型,野外难以识别.代家庄铅锌矿床的发现,反映了该区成矿的多样性和复杂性.说明泥盆系铅锌矿带继续向西延伸,含矿层位向西也有逐渐抬高的趋势,并且出现了新的成矿类型.因此,要用新的找矿思路重新认识区内成矿环境,用新的我矿模型指导地质勘查,以取得找矿的新突破. |
| 英文摘要: |
| Daijiazhuang lead - zinc deposit is a new discovery in the western Qinling Devonian lead - zinc metallogenetic belt in recent years. The deposit is a carbonate type mainly composed of cernssite and smithsenite. It is a new type deposit different from sulphide type in this area, and difficult to be distinguished in the field. The finding of the deposit represents nature of metallogenetic variety and complexity in the area, showing that Devonian lead - zinc metallogenetic belt can extend to the west and ore - beating strata run - up gradually to the west with a new metallogenetic type. We should reconsider metallogenetic environment using new thinking of ore -finding, and use new prospecting model to guide geological exploration in order to make a new breakthrough for ore - finding. |
