Henan Province is rich in graphite resources,and the reserves of identified resources rank the third in China.It is one of the most important raw material sources for the graphite industry in China. Therefore,it is very important for metallogenic prediction,prospecting potential evaluation and mineral development to strengthen the study of geological characteristics of deposits,divide metallogenic zones,summarize metallogenic regularities and study the genesis of deposits. On the basis of the comprehensive collection,sorting and research of the results of the graphite ore exploration in Henan Province,the focus is on the study of the ore-bearing strata,deposit characteristics and metallogenic zone division. The study results show that:（1） The graphite deposit in Henan Province is a single type,which is a regional metamorphic crystalline graphite deposit. The metallogenic age is Neoarchean and Paleoproterozoic.（2） Jiudigou Formation of Taihua Group,Yanlinggou Formation of Qinling Group and Dagou formation of Douling Group all have the characteristics of khondalite series. They are the main metallogenic strata with the strongest graphite mineralization and great prospecting potential.（3） The Chishangou Formation of the Yinyugou Group has the characteristics of black rock series,and the graphite mineralization is relatively weak,which is the secondary ore formation.（4） The graphite ore in Henan Province has the advantages of large scale,high grade and easy ore selection,which has important industrial significance. Based on the classification of metallogenic regions（Grade Ⅰ）,metallogenic provinces（Grade Ⅱ） and metallogenic belts（Grade Ⅲ） in China,the graphite metallogenic belt in Henan Province is further divided into 4 graphite metallogenic subbelts（Grade Ⅳ） and 8 graphite ore concentration areas（Grade Ⅴ）. The graphite metallogenic subbelts are distributed from north to south,and the graphite mineralization changes from weak to strong from north to south. It is exactly consistent with the distribution and mineralization regularity of metallogenic strata.

Laozhuang diopside–tremolite deposit in Nanzhao county is the only diopside–tremolite deposit in Henan Province. The mining area is located in the north of Luanchuan–Minggang regional fault, and the tectonic position is in the south margin of North China block. There are two diopside–tremolit eorebodies in the mining area, which occur in the upper part of Nannihu formation of Luanchuan group of Qingbaikou system in stratoid form. The orebody morphology is simple. The wall rock alteration are mainly tremolite and diopside, followed by potassic feldspar and phlogopitization. The natural types of ores are mainly phlogopite diopside skarn, phlogopite diopside skarn and phlogopite diopsides karn. The mineral composition is mainly tremolite and diopside, followed by potash feldspar and phlogopite, a small amount of calcite. The chemical composition of the ore are SiO2, CaO, MgO and Al2O3, followed by FeO, K2O, Na2O and CO2. Ore grade: tremolite + diopside (Tl + Di) is relatively high and stable, and the average ore grade (Tl + Di) is 68.25%. The preliminary test of diopside raw ore replacing wollastonite in the production of glazed tile shows that the product has stable performance and obvious energy saving effect. The deposit belongs to skarn type and the metallogenic epoch is early Cretaceous. The formation of the deposit is controlled by early Cretaceous Zhuyuan quartz syenite porphyry, dolomite marble in the upper Nannihu formation and interlayer fracture zone. Skarn stage is the main metallogenic stage. Diopside is formed in dry skarn stage, tremolite is formed in wet skarn stage, and potash feldspar, phlogopite and calcite are formed in oxidation stage.

河南栾川冷水—赤土店钼钨铅锌多金属矿位于华北陆块南缘金银多金属成矿带上的栾川钨钼矿集区内,以野外地质调查、物探、钻探等为主要技术手段,在矿区开展了地质勘查及研究工作,共圈定了钨钼矿体8条,提交钼资源量631.17万t,WO3138.28万1,钼钨资源量达超大型规模.对矿区地质特征、矿床地质特征及成因进行了详细探讨.根据矿体特征、控矿因素、矿化类型,结合前人在该区开展的硫同位素分析和含矿斑岩的SHRIMP、辉钼矿Re-Os同位素年龄成果,综合研究认为:①该矿床主要赋存地层为官道口群白术沟组和栾川群三川组、南泥湖组、煤窑沟组;②矿化以钼矿化为主,钼钨矿体主要受深部侏罗纪末花岗岩基和逆冲推覆构造体系的联合控制,燕山期中酸性侵入岩(小岩体)与区内钼钨等成矿联系密切,花岗质岩浆为钨钼等成矿元素的主要来源,含矿斑岩为主要成矿地质体;③含矿岩浆在运移过程中由于温度变化和围岩的差异,从而使不同的成矿元素组合出现明显的分带现象,并形成不同类型的矿化(床),矿床成因类型为斑岩—矽卡岩型,成矿时代为135～157 Ma.在上述分析的基础上,建立了钨钼铅锌多金属矿的成矿模式和综合找矿模型,对于栾川及豫西地区钼钨矿的找矿工作有一定的参考价值.

Xihuhechulu area is located in the north of Da Hinggan Mountains.It is covered by forest or bog under natural conservation;the geological survey in this area is not enough and no deposits have been discovered.Recent geochemical survey results show that Ag,Pb,W,As,Sb,and Bi are rich,especially in the Carboniferous Moergenhe Formation and Early Carboniferous diorite and Late Devonian quartz-diorite,but Cu,Au,and Sn are relatively depleted comprised with the crust Clarke value.Most metallogenic elements are not evenly distributed in the area,especially,Au,Ag,Mo and Bi strongly differentiate in the outcrops of the Jurassic Manketouebo Formation and Carboniferous monzonitic granite and diorite.Cu is in strong differentiation in the Devonian Daminshan Formation and Early Cretaceous granite,and Au is also in strong differentiation in the Carboniferous Moergenhe Formation and Late Devonian quartz-diorite,and very rich in some local areas.In this area,the main metallogenic elements are Au,Pb,Ag,Mo,and Cu and the associated metallogenic elements are W,As,Sb,Sn,Mn,Bi and Zn,mainly in hydrothermal and volcanic metallogenic types.According to the regional geochemical characteristics,Xinihe—Narisimaode,Dajiazishan and Yizhigou—Xiaogushan may be high metallogenic potential areas.
