与火山-侵入活动有关的铁矿床
这类矿床是指与火山岩、次火山岩有成因联系的铁矿床。成矿作用与富钠质的中性(偏基性或偏酸性)、基性火山岩侵入活动有关。以成矿地质背景为基础，按火山喷发环境，可分为陆相火山-侵入型铁矿床和海相火山-侵入型铁矿床。
1.陆相火山-侵入型铁矿床
在中国东部陆相安山质火山岩分布区，发育着一套与辉石闪长玢岩-次火山或火山侵入岩有空间、时间和成因联系的铁矿床。典型矿床产于宁(南京)芜(湖)地区的中生代陆相火山岩断陷盆地中，同偏碱性玄武安山质火山侵入活动有密切的成因关系。国内有人称之为“玢岩铁矿”。它实际包括由岩浆晚期-高温、中温，直至中低温一系列成因类型。按矿床在火山机构中的产出特点，大致可分为3类：①产于玢岩体内部、顶部及其周围火山岩接触带中的铁矿床，如“陶村式”、“凹山式”、“梅山式”等。②产于玢岩体与周围接触带中的铁矿床。如“姑山式”等。③产于火山碎屑岩中的火山沉积矿床，如“龙旗山式”等。其中以第①类矿床规模最大，矿石含铁较高。
陆相火山-侵入型铁矿床，矿体常呈似层状、透镜状、囊状、柱状、脉状等。矿体规模大小不一，大型矿体长可达千米以上，厚数十至二三百米，宽数十至近千米。矿石矿物以磁铁矿为主，假象赤铁矿、赤铁矿次之，可见少量菱铁矿。矿石构造有块状、浸染状、角砾状、斑杂状、条纹条带状等。这类矿床的磁铁矿以含Ti、V为特征。
2.海相火山-侵入型铁矿床
多产于地槽褶皱带海底火山喷发中心附近，铁矿床的形成与火山作用有直接的关系。典型矿床以云南大红山铁矿为代表。
铁矿体赋存于由火山碎屑岩-碳酸盐岩-熔岩(细碧岩和角斑岩)组成的一套含矿建造中。下部为石英砂岩、钙质或硬砂质粉砂岩，夹泥灰岩、白云质灰岩和粉砂岩薄层；富钠质的浅色岩是主矿体的容矿岩层。上部为厚层大理岩。
矿体常呈层状、似层状、透镜状，少数呈脉状或囊状，常成群成带出现。矿石构造主要有块状、浸染状、角砾状、条带状、杏仁状和定向排列构造等。矿石矿物主要为磁铁矿、赤铁矿，次有假象赤铁矿、菱铁矿和硫化矿物。脉石矿物有石英、钠长石、绢云母、铁绿泥石等。

With the volcano intrusive activities related to iron ore deposits

This kind of deposit refers to the deposit of iron ore has genetic relationship with volcano volcano rock, rock. Mineralization and sodium rich neutral (partial basic or acidic), basic volcano intrusive activities related to. In the metallogenic geological background as the basis, according to the volcano eruption environment, can be divided into continental volcano intrusive bed and marine volcano - type iron intrusive type iron deposit.

The 1 continental volcano intrusive type iron deposit
在中国东部陆相安山质火山岩分布区，发育着一套与辉石闪长玢岩-次火山或火山侵入岩有空间、时间和成因联系的铁矿床。典型矿床产于宁(南京)芜(湖)地区的中生代陆相火山岩断陷盆地中，同偏碱性玄武安山质火山侵入活动有密切的成因关系。国内有人称之为“玢岩铁矿”。它实际包括由岩浆晚期-高温、中温，直至中低温一系列成因类型。按矿床在火山机构中的产出特点，大致可分为3类：①产于玢岩体内部、顶部及其周围火山岩接触带中的铁矿床，如“陶村式”、“凹山式”、“梅山式”等。②产于玢岩体与周围接触带中的铁矿床。如“姑山式”等。③产于火山碎屑岩中的火山沉积矿床，如“龙旗山式”等。其中以第①类矿床规模最大，矿石含铁较高。
In Chinese Eastern Lu Xiangan Hill distribution area of volcano rock, developed a set of and pyroxene diorite porphyrite - volcano or volcanic intrusive rocks have the space, time and genetic relationship of iron deposit. The typical ore deposit in Ning (Nanjing) Wu (Lake) basin of Mesozoic continental volcano rock area fault, with alkaline basaltic andesitic volcano intrusive activities have a close genetic relationship. China has called "porphyrite iron ore". It actually consists of late magmatic - high temperature, medium temperature, low temperature until a series of genetic type in. According to the production features in the volcano in the mechanism of deposit, can be roughly divided into 3 categories: iron ore deposit occurs in the internal of porphyrite body, top and around the volcano rock contact zone, such as "Tao Cun type", "concave mountain type", "Meishan". Iron ore deposits found in and around the porphyrite body in contact with. Such as "Gushan type" etc.. The volcano sedimentary deposits found in volcano clastic rocks, such as "dragon Qishan type" etc.. Among the first class of the largest iron ore deposits, higher.

Continental volcano intrusive iron ore deposits, orebodies usually stratoid, lenticular, saccate, columnar, vein. The ore body size, large ore bodies up to 1000 meters above the long, thick tens to two hundred or three hundred meters wide, dozens of kilometers to nearly. The ore minerals are dominated by magnetite, hematite, hematite pseudomorphs of siderite, a small amount of. The ore textures are massive, disseminated, breccia, mottled, banded etc.. This type of ore deposits of magnetite with Ti, V as feature.

Prolific in the geosyncline fold belt near an undersea volcano eruption center, there is a direct relationship between the forming of the deposit and the volcano action. The typical ore deposit in Yunnan Dahongshan Iron Mine as the representative.

Ore bodies occur in by the volcano clastic - carbonate - lava (spilite and keratophyre) consisting of a set of ore formation in. The lower part is a quartz sandstone, calcareous or hard sandy siltstone, intercalated with marls, dolomitic limestone and siltstone layer; sodium rich light rock is the main ore bodies in the ore bearing strata. The upper part is a thick layer of marble.

The ore bodies are usually layered, stratoid, lenticular, and a few veins or saccate, often in a band appeared. There are massive, disseminated, breccia, banded, almond shaped and aligned structure of main ore structure. Ore minerals are mainly magnetite, hematite, time illusion hematite, siderite and pyrite.
