河南栾川冷水地区钼钨铅锌矿田成矿系列及找矿方向

河南栾川冷水地区钼钨铅锌矿田位于华北陆块南缘与秦岭造山带的交接部位,是中国重要的钼钨铅锌多金属成矿区,现已证实,冷水地区下部为一大型燕山期岩浆岩体群,斑岩沿早期近EW向、SN向断裂贯入,在交汇处形成岩体群及大规模矿化,交汇点之外形成单个小岩珠及小规模矿化.成矿系列划分为斑岩型、矽卡岩型及热液充填交代型矿床.三类矿床在空间上具明显的分带性,形成时间具相近性,此矿区仍具有良好的找矿前景.

Ore-Forming Series of Molybdenum-Lungsten-Lead-Zinc Polymetallic Mine Field: Guides to Discover Deposits in the Lengshui Area, Henan Province

Lengshui area molybdenum tungsten lead zinc mine field, Henan Province, located at the junction of the South Margin of the North China Platform with the Qinling Tectonic Belt where is the most important ore-forming area for molybdenum, tungsten, lead, zinc polymetallic ore deposits. It has been proved that a cluster of magmatic bodies intruded below the Lengshui area. Porphyry formed in early faults, which extend approximately East-West or North - South direction and the Groups of magma intrusion and deposit with ~arge scale occurs at the junctions of the two faults. Small magmatic intrusions and subeconomic deposits occur in other places. Ore-forming series can be divided into the porphyritic type, skam type and 1 thermal-filled type deposits. Zonal characteristics of these three type deposits are distinct in spaces and formed in a good order. Therefore, this mining-area also has a beneficial prospect to mining.
