摘要
Abstract
The discovery of Laoliwan silver deposit is an important ore -searching achievement in Luoning County , Henan Province .On the basis of detailed research on metallogenic background , geological characteristics and ore -controlling factors of Laoliwan deposit , it could be concluded that tectonic conditions are major ore -controlling factors , and ore-bodies occured in five tectonic altered rock belts within the fault zone .Mineralization was closely related to magmatic rocks .Ore-forming elements were distributed in the inner and outer contact zone of porphyritic monzonitic gran -ite and faulted fracture zones .Irregular shaped mineralization enrichment zone was generally formed in the top part of magmatic rocks .Intensive rock alteration was well developed within the deposit . Alteration zonation was characterized by parallel and symmetrical distribution from the center ( frac-ture) to the outside (wall rocks).Combined with geochemical anomaly results , it can be conclu-ded that additional prospective resources in Laoliwan can include a large silver deposit and a medi -um lead-zinc ore deposit .Furthermore , there is a huge potential for prospecting same type silver deposits in Laoliwan and adjacent areas .关键词
