Since the founding of New China, it has been Proved through geological reconnaissance and exploration that China is rich in iron ore resources and ranks the third in the world. In this Paper, firstly a review of the historical course of iron exploration in China is given. Then following features of Chinese iron ore resources are mentioned: 1) A wide distribution over the country (densely crowded in certain provinces) -China (excluding Taiwan)nowadays has seven important iron metallogenetic provinces with productive area of 1800 in number; 2) A variety of metallogenetic conditions and ore deposit types-Sedimentary metamorphiciron deposit is of the chief type with a reserve amounted 54.4% of the total. Next to it are magmatic,contact-metasomatic, hydrothermal sedimentary, volcanogenic and weatheringresidual types, ranked in their importance; 3) Low grade ores hold a dominant position,and the ratios of high grade to low grade ores for different types of ore deposits are given in the paper;and 4) Many useful components are associated with the iron deposits. They are: V, Ti,RE,Nb, Cu, Sn, W, Mo, Pb, Zn, Co, and Au. At the endlof the paper, the author gives a brief account about the Perepective of iron ore resource of our country and points out thatin the eastern part many potential areas remain to be further prospected because the depth of Prospecting for those known iron deposits are not sufficently large, while in the western part, because the degree of geological exploration was low in the past. new prospective areas maybe found.Inshort, a hopful future of China's iron ore resources is in existence.

新中国成立以来,经普查勘探证明我国铁矿资源丰富,探明储量占世界第三位。文中首先叙述了我国铁矿勘查开发的历史,接首分析了我国铁矿资源的四个特点:①分布广泛,又相对集中。目前全国(不含台湾省)有铁矿产地1800多处,重要的成矿区有7个。②成矿条件多样,矿床类型齐全。以沉积变质型铁矿为主,占总储量的54.4%,其次是岩浆型、接触交代—热液型、沉积型,还有火山岩型和风化残积型。③以贫磁铁矿为主。列举了各种类型铁矿中富矿所占比例。④多组份共生铁矿多,综合利用价值高。共(伴)生的有益元素主要有钒、钛、稀土、铌、铜、锡、钨、钼、铅、锌、钴和金等。最后,对我国铁矿资源的远景作了展望。指出东部地区已知矿床勘查深度较浅,并仍有很多有望区;西部地区地质工作程度尚低,有找矿前景,估计我国铁矿远景很可观。

Water in ore-bearing hydrothermal system derives from different origins-magmatic,descending meteoric,connate,marine,metamorphic and mantle-derived waters.The isotopic composition of hydrogen and oxygen differs in these waters. Magmatic water is the main mineralizing medium of magmatic hydro-thermal deposits. Meteoric water and connate water may form independent ore-bearing solution through circulation by heating, or may mix with ascending magmatic solution, or enter magmatic chamber in the depths to join...

Water in ore-bearing hydrothermal system derives from different origins-magmatic,descending meteoric,connate,marine,metamorphic and mantle-derived waters.The isotopic composition of hydrogen and oxygen differs in these waters. Magmatic water is the main mineralizing medium of magmatic hydro-thermal deposits. Meteoric water and connate water may form independent ore-bearing solution through circulation by heating, or may mix with ascending magmatic solution, or enter magmatic chamber in the depths to join the ore-bearing hydrothermal system. In submarine environment, the hydrothermal system of submarine cyclic water becomes the major medium of mineralization of submarine hydrothermal-sedimentary deposits. Metamorphic water constitutes most of ore-bearing metamorphic hydrothermal water, which tends to mineralize in metamorphic front region and before the front region. Along deep faults, mantle primary water may automatically rise into the upper crust to mineralize there, or rise with magmatic melt, or even enter metamorphic belts to become part of the ore-bearing hydrothermal system. In the crust, some deposits are formed by a single fluid,and others formed by a mixture of two fluids or more.

成矿热液系统中水是多来源的,有岩浆水、下降的天水、同生水、海水、变质水及地幔初生水等,这些水都各有不同的氢、氧同位素组成。岩浆水由岩浆结晶分出面形成岩浆热液及其有关矿床;下降天水和同生水受热循耳可形成独立的合矿热液,也可与上升岩浆热液混合或从深部进入岩浆房参加热液成矿系统;在海底成矿环境中海水循环热液系统是海相热液—沉积矿床的主要成矿介质;变质水则是含矿变质热液的主体并趋向于在变质前锋区及前锋区前成矿;地幔初生水可沿深大断裂自动上升到地壳浅部成矿,也可随岩浆熔体上升或进入变质带进而参加热液成矿系统。在地壳中,有单一热波形成的矿床,两种或多种流体混合形成的矿床也不乏其例。
