| 中文摘要: |
| 河南芦家坪银多金属矿是一个典型的碰撞造山带型脉状矿床,产出于北秦岭褶皱带二郎坪地体早古生界二郎坪群内,矿体形态较为简单,表现为单脉,主要呈似层状或不规则状,金属矿物以独立矿物(银金、辉银矿)、硫化物形式赋存,银、铅、锌共生关系密切。通过对区域地质背景、矿区地质、矿床地质等方面的研究,探讨其成因,查明矿床具明显的碰撞造山改造作用、后期岩浆热液强烈叠加,属造山型中低温热液型矿床。 |
| 英文摘要: |
| The Lujiaping silver polymetallic deposit is a typical collision orogenic belt type vein deposit, which is produced in the Erlangping group of the early Paleozoic Erlang Ping area in the northern Qinling fold belt. The form of the ore body is simple, showing a single vein, mainly in the form of stratiform or irregular shape. The metal minerals are in the form of independent minerals (Yin Jin, Hui Yinkuang) and sulfide. The symbiotic relationship between silver, lead and zinc is close. Through the study of regional geological background, mining geology and ore deposit geology, the causes are discussed. It is found that the ore deposit has obvious impact orogenic transformation and late magmatic hydrothermal superposition, which belongs to the middle and low temperature hydrothermal deposit of orogenic type. |
