What are the types of iron ore deposits in my country?

Late magmatic differentiated iron deposits
Produced in basic and ultrabasic igneous rocks such as gabbro and peridotite
The ore has disseminated, striped, and massive structures, iron-inlaid crystal structure, and solid solution separation structure.
The metal mineral deposits are mainly titanomagnetite (a composite mineral system composed of ilmenite lamellae, magnesia-aluminum spinels, ilmenite spar, and magnetite), followed by granular ilmenite and a small amount of magnetic yellow. Iron ore, pyrite and other cobalt-nickel sulfides, chromite. Gangue mineral deposits include pyroxene, basic plagioclase, olivine, apatite, etc.
Cu, Co, Ni, Mn, P, Se, Te, Sc, Ga and platinum group elements, etc.
Panzhihua Iron Mine

Late magmatic penetrating iron deposit
Produced in gabbro and anorthosite rock bodies, the ore bodies are distributed along certain cracks in the rock mass, or produced in the contact zone between gabbro and anorthosite
The ore has a fine block and disseminated structure. The fine block has a high iron content, and has a sponge iron loss structure, a granular mosaic structure, a texture structure and a solid solution separation structure. In the disseminated ore, due to the vanadium-titanium magnet The severe alteration of the ore resulted in the formation of altered residual structures.
Metal mineral deposits mainly include vanadium-containing titanium magnetite, ilmenite and a small amount of chromite, pyrite, chalcopyrite and secondary hematite, limonite, etc. Gangue mineral deposits mainly include plagioclase and chlorite, followed by pyroxene, fiber amphibole, calcite and a small amount of phosphorite, biotite, talc, quartz, olivine, etc.
Co, Ni, Cu, S, P
Shallow marine phase accumulation iron deposits
Mainly produced in sandstone and sandy shale
It is mainly ooid structure, in addition, there are also bean-like and -like structures.
The metal mineral deposits mainly include hematite, followed by siderite and partially magnetite. Gangue mineral deposits mainly include quartz
Xuanhua Longyan Iron Mine (Xuanlong Style), Hubei Changyang Huoshaoping, Guandian Iron Mine Area (Ningxiang Style)
Sea-land replacement – lacustrine accumulation iron deposits
Iron-bearing layers are often closely related to coal-bearing strata. Some mineral layers are produced on the corrosion surface of carbonate rocks and are symbiotic with bauxite and clay minerals.
The structure type is messy, generally showing a fine grain structure, the particles are cemented to each other, and the particle size is fine and uneven.
The metal mineral deposits are dominated by hematite or siderite, or perhaps both. Gangue minerals include chlorite, quartz, clay minerals, etc.
Produced in old metamorphic rock systems, mostly large deposits
The ore has many striped and striped structures, granite crystallization and scale crystallization structures.
Metal mineral deposits are generally dominated by magnetite, with a few mining areas containing hematite and more false hematite. The ores generally contain iron phosphate and iron silicate, and the content in individual mining areas is relatively high. Gangue mineral deposits include quartz, chlorite, mafic amphibole, almandine garnet, biotite, carbonate mineral deposits, etc., generally containing a small amount of pyrite
Anben area iron ore
Metamorphic carbonate iron ore
Produced in various rock formations such as phyllite, marble, and slate or on their contact surfaces
The ore structure is mainly massive, followed by ooid and striped shapes.
Metal mineral deposits include hematite, siderite, magnetite, and limonite. Gangue minerals include quartz, sericite, chlorite and carbonates
Jilin Dalizi Iron Mine
Touch to inform-hydrothermal iron deposit
Mainly produced in the contact zone between medium-acid intrusive bodies and carbonate rocks
The ore mainly has block structure, followed by disseminated structure. There is also a brecciated structure, with a dense and granular structure
The metal mineral deposits are mainly magnetite, followed by false hematite, and some mining areas show more siderite. The sulfide is mainly pyrite, with chalcopyrite, galena, sphalerite, molybdenite, etc. in some areas. A few deposits contain cassiterite and colloidal tin. The gangue mineral deposits are mainly diopside and garnet, followed by hornblende and carbonate mineral deposits; in some mining areas, the gangue mineral deposits contain more serpentine.
Cu, Co, Ni, Pb, Au, Ag, Mo, W, Sn, S, etc.
Daye Iron Mining Area, Hanxing Iron Mining Area
Weathering and leaching iron ore area
Produced in weathered leaching zones of various primary iron ores and other iron-bearing rocks
Ore has block, honeycomb, grape-like or earth-like structure
The metal mineral deposits are mainly porous limonite. Gangue minerals include quartz, carbonate, clay minerals, etc.
Iron deposits related to continental volcanic-intrusive activity
Produced in volcaniclastic rocks or in the volcanic rock contact zone inside, on top of and around the porphyry body, and in the contact zone between the porphyry body and the surrounding accumulation rocks
Structures such as massive, disseminated, disseminated vein-like, brecciated, mottled, striped, etc.
Some material mineral deposits are dominated by magnetite, followed by false hematite and hematite, and some are dominated by false hematite. Siderite content varies from mining area to mining area. Gangue mineral deposits include diopside, actinolite, apatite, alkaline feldspar, pyrite and gypsum, etc.
It is mainly produced near the seamount eruption center in the geosyncline fold zone. The ore body occurs in the pyroclastic rock-carbonate rock-lava formation.
The structure is the same as the deposits related to continental volcanic immersion activities, and has an almond-shaped structure, directional placement structure, etc.
The metal mineral deposits in the ore include magnetite and hematite, as well as false hematite, siderite and sulfide. Gangue mineral deposits include quartz, albite, sericite, iron chlorite, etc.
Iron ore bodies mainly occur in dolomite and dolomitic crystalline limestone
Sheet, block, disseminated and band-like structures. Metamorphic structure
The metal parts deposits are mainly hematite, with a small amount of magnetite, semi-false hematite and iron jasper. Gangue mineral deposits mainly include quartz
Produced in dolomite or in the contact zone between dolomite and siliceous slate
Fine massive, striped and disseminated structures; grain-like structures and patchy structures
Metal mineral deposits mainly include magnetite and hematite, containing a small amount of sulfide and a large amount of rare earth minerals. Gangue minerals include fluorite, sodium pyroxene, diorite, etc.
