Geological Characteristics And Forecast Of Liushanyan Copper-zine Belt In Tongbai,Henan Province

Tongbai area is one of the important metallogenetic belts in China.In this paper,we have studied of typical mine about Liushanyan Copper-Zinc Mine in Tongbai,Henan Province.Ore-forming geological body,ore-forming structure and structure plane,ore-forming feature of the Liushanyan copper-zinc mine belt are studied by using the “trinity” ore-prospecting and prediction theory.The main results are as follows:1.After summing the geological characteristics of the Liushanyan copper-zinc ore belt,we are considered that the Liushanyan copper-zinc mine belt is a type of copper-zinc mine of early submarine volcanic exhalation sedimentary superimposition and later hydrothermal transformation.2.According to the comprehensive research results,it is considered that the oreforming geological body of the Liushanyan copper-zinc mine belt is the “Geological bodies of ore-bearing formation of quartz hornblende porphyry with syngenetic breccia” which formed in a low-lying venting pool in a submarine volcanic exhalative sedimentary basin,and the metamorphosed keratophyre,quartzite keratophyre assemblage occur at the top of volcanic eruption sedimentation rhythm,respectively.3.It is can be divided into two types about Liushanyan Copper-Zinc Mine belt:the early submarine volcanic exhalative sedimentary basin metallogenic structural system and the late brittle fault metallogenic structural system.4.There are two types of ore-forming structural planes in the Liushanyan copper-zinc mine belt: One is the ore-forming structural plane related to the sedimentary ore-forming structure system,such as Lithologic metallogenic structural plane formed by volcanic eruption rhythm of intermediate-basic sphalerite,tuff and acid tuff,quartz keratophyllite.The other is the ore-forming structural plane related to the fault structure,such as the F1 compressive fracture plane in the LiushanyanMoershan ductile-brittle fracture zone.5.We established the prospecting model of Liushanyan copper-zinc mine belt on the basis of prospecting information obtained from exploration and scientific research in the past.On this basis,two prospecting targets have been delineated respectively,one is the prediction target area of ? anomaly zone(grade A),and the other is the copperzinc ore prediction target area(grade B)of Nianpangou ore section.
