接触交代-热液型铁矿床
接触交代型矿床，常称为夕卡岩型矿床。主要赋存于中酸性-中基性侵入岩类与碳酸盐类岩石(含钙镁质岩石)的接触带或其附近。这类矿床一般都具有典型的夕卡岩矿物组合(钙铝-钙铁榴石系列、透辉石-钙铁辉石系列)，而在成因和空间分布上，都与夕卡岩有一定的关系。
岩浆岩侵入体的形成时代，从加里东期、海西期、印支期，到燕山期都有。在中国以燕山期最为重要。
碳酸盐类岩石生成时代，从前震旦纪到侏罗纪都有，岩性也很不相同。就已知国内夕卡岩型铁矿围岩而言，包括灰岩、大理岩、白云质灰岩、泥灰岩、各种不纯质的灰岩、白云岩；部分围岩可为角岩、片岩、板岩、砂岩或凝灰岩等。从岩性的时代来看，元古宙(包括震旦纪)多为硅质灰岩；寒武纪—奥陶纪多为纯质灰岩或含镁质灰岩；石炭纪-二叠纪多为含泥质及有机质灰岩。中国北方最有利形成接触交代型铁矿的是寒武纪-奥陶纪灰岩，南方主要是三叠纪大冶灰岩和早二叠世栖霞灰岩。
接触交代型铁矿大部分形成于接触带，有的矿体可延伸到非夕卡岩的围岩之中，矿体常成群出现，形态复杂，多呈透镜状、囊状、不规则状和脉状等，矿石矿物成分较复杂。铁矿石以块状构造为主，次为浸染状、斑点状、团块状和角砾状构造。该类铁矿常伴生有可综合利用的铜、钴、金、银、钨、铅、锌等；甚至构成铁铜、铁铜钼、铁硼、铁锡、铁金等共(伴)生矿床。矿床规模以中小型为主，也有大型。
这类铁矿在中国分布十分广泛，主要集中在河北省邯(郸)—邢(台)地区、鄂东、晋南、豫西、鲁中、苏北、闽南、粤北以及川西南、滇西等地，是中国富铁矿石的重要来源。
按岩浆岩和围岩条件，在工业上常分为邯邢式、大冶式和黄岗式铁矿。邯邢式铁矿围岩主要是中奥陶统马家沟组灰岩，矿体常呈似层状。大冶式铁矿围岩主要为三叠系大冶灰岩，矿体形态不规则。黄岗式铁矿成矿岩体为花岗岩及白岗岩，围岩为古生界碳酸盐岩夹火山岩系。
热液型铁矿床明显受构造控制，有的是断裂控矿，有的是褶皱控矿，还有断裂与褶皱复合控矿。热液型铁矿床与岩浆岩的关系常因地而异，多数矿体与岩体有一定距离。高温热液磁铁矿、赤铁矿矿床常与偏碱性花岗岩、花岗闪长岩、闪长岩类有关，中低温热液赤铁矿矿床常与较小的中酸性侵入体有关，两者多保持一定的距离。中低温热液菱铁矿矿床与侵入体无明显关系。围岩条件对热液型铁矿的控制作用不甚明显。围岩蚀变是热液型铁矿的显著特征，高温矿床常见透辉石化、透闪石化、黑云母化、绿帘石化等；中低温矿床多见绿泥石化、绢云母化、硅化、碳酸盐化等。
大多数热液型铁矿体较小，常成群出现。矿体呈脉状、透镜状、扁豆状，多见分支复合，膨胀收缩，尖灭再现现象。矿石组合简单，矿石品位一般较高。矿床规模以中小型为主。分布于内蒙古、吉林、山东、湖北、广东、贵州和云南等省、自治区。但也有大型矿床，如山东淄河一带，产于上寒武统—中奥陶统碳酸盐类岩石中的文登铁矿床，该矿床为浅成-低温热液充填交代矿床。矿床由22个矿体组成，呈似层状和透镜状，重叠平行分布。主矿体长7000m，厚12～36m，延深100～470m。矿石矿物以褐铁矿、菱铁矿为主。矿石品位TFe平均41%(褐铁矿)、30%(菱铁矿)，探明铁矿石储量1.16亿t，其中炼铁用矿石储量5400万t。

Contact metasomatic deposits, often called the skarn type deposit. Mainly occur in acidic intermediate mafic intrusive rocks and carbonate rocks (rocks containing calcium and magnesium) or near the contact zone. This type of deposit is generally has the typical skarn mineral assemblages (calcium aluminium - andradite series, diopside hedenbergite Series), and in the genesis and spatial distribution, and skarn has certain relation.

Magmatite intrusion age of formation body, from Caledonian, Hercynian, Indosinian period, Yanshan period have to. In Yanshan period is the most important in China.

The carbonate rock formation of Sinian to Jurassic age, once have, lithology is also not the same. Known domestic skarn type iron ore rock, including limestone, marble, dolomitic limestone, marl, impure matter limestone, dolomite; part of wall rock for hornfels, schist, slate, sandstone and tuff. From the era of lithology, Proterozoic (including the Sinian) for siliceous limestone of Cambrian and Ordovician; for pure limestone or containing magnesian limestone; Carboniferous - Permian for argillaceous limestone and organic matter. The most favorable China North forming the contact metasomatic iron deposit is the Cambrian - Ordovician limestone, the south is mainly Daye Triassic limestone and Early Permian in Qixia limestone.

Contact metasomatic iron deposit formed in the contact zone of most, some ore bodies can be extended to non skarn rock, ore bodies often appear in groups, complex shape, lenticular, saccate, irregular shape and vein, mineral composition is relatively complex. Iron ore on a massive structure based, for disseminated, speckled, lumps and brecciated structure. The type of iron ore is often associated with comprehensive utilization of copper, cobalt, gold, silver, tungsten, lead, zinc and so on; even form iron copper, iron, copper and molybdenum iron boron, tin, iron iron gold CO (with) deposit. Deposit scale based small and medium, there are also large.

This type of iron ore is very widely distributed in Chinese, mainly concentrated in Hebei province Han (Dan) - Xing (Taiwan) area, Eastern Hubei, Jinnan, western Henan, Lu Zhong, North Jiangsu, Southern Fujian, northern Guangdong and southwest Sichuan, Yunnan and so on, is an important source of China rich iron ore.

According to the magmatite and surrounding rock conditions, in the industry often divided into Hanxing type, Daye type and Huang Gang type iron ore. Hanxing type iron ore rock is mainly the Middle Ordovician Majiagou Formation limestone, stratoid orebodies usually. Daye type iron ore rock mainly Triassic of Daye limestone, orebody shape irregular. Huang Gang type iron ore rock is granite and granite, rock paleozonic carbonate volcano rock series clamp.

Hydrothermal deposit are obviously controlled by structures, some are ore controlling fault, some folds and ore control, fault and fold complex ore. The relationship between hydrothermal deposit and magmatite often vary, most ore body and rock mass has a certain distance. High temperature hydrothermal magnetite, hematite deposit ordinary and partial alkaline granite, granodiorite, diorite related, low to moderate temperature hydrothermal hematite deposit often associated with smaller intermediate acid intrusive body, both to maintain a certain distance. Low temperature hydrothermal siderite deposit has no obvious relation with intrusive body. The control effect of surrounding rock conditions of hydrothermal type iron ore is not obvious. The wall rock alteration is a significant feature of hydrothermal ore deposits, high temperature common diopside tremolite petrochemical, petrochemical, biotitization, epidotization; low temperature ore deposit in rare chloritization, sericitization, silicification, carbonation etc..

Most hydrothermal type ore body is smaller, often appear in groups. The ore bodies are in vein, lenticular, lenticular, see more branch composite, expansion and contraction, reproduce pinch phenomenon. The simple combination of ore, ore grade is generally higher. Deposit scale based small and medium. Located in Inner Mongolia, Jilin, Shandong, Hubei, Guangdong, Guizhou and Yunnan provinces, autonomous region. But there are also large deposits, such as the Shandong Zihe River area, Wendeng iron ore deposit in the late Cambrian Middle Ordovician carbonate rocks in the deposit, as hypabyssal epithermal filling metasomatic deposit. The deposit consists of 22 ore bodies, stratoid and lenticular, overlapping parallel distribution. The main orebody is 7000m long, thick 12 ~ 36m, 100 ~ 470m extension. Ore minerals are mainly limonite, siderite. The average TFe of 41% (limonite ore grade), 30% (siderite), proven iron ore reserves of 116000000 T, which for making iron ore reserves of 54000000 t.
