Which of the following main types of iron ores are found in …
The correct answer is 1 and 2 only. Key Points. There are four types of iron ores, viz. hematite, magnetite, limonite, and siderite. India is endowed with fairly abundant resources of iron ore and has the largest reserve of iron ore in Asia. The two main types of ore found in India are hematite and magnetite. Hence Option 1 is correct.
Siderite
The most common iron carbonate is siderite (FeCO3 ), a frequent constituent of carbonate sediments and rocks on Earth. Siderite has a low-temperature transition at 30–35 K ( Housen et al., 1996 ), distinctively different from that of pyrrhotite ( Section 5.08.3.9 ). Siderite is paramagnetic at ordinary temperatures and carries no NRM.

Siderite – WGNHS – UW–Madison
Siderite forms as a sedimentary precipitate, in hydrothermal veins, in metamorphic rocks formed from such protoliths, and, rarely, in pegmatites. In sedimentary environments it forms in extensive beds of banded iron formations and as more localized deposits of bog-iron ore. It readily weathers to iron oxides.

Siderite
Siderite is some shade of brown or brownish yellow. It is more dense (3.96) than other common carbonates because of iron content. It occurs as an earthy mass or as concretionary nodules (clay ironstone) in iron-rich sedimentary rocks. Crystals form in hydrothermal veins and it may be found in banded iron formations from the Precambrian.
Iron Ore Deposits
In East Texas both siderite (iron carbonate) and limonite (iron oxide) exist in large quantities, primarily in Anderson, Cass, Cherokee, Harrison, Henderson, Houston, Leon, Marion, Morris, Nacogdoches, Smith, Upshur, Van Zandt, and Wood counties, where the ore deposits occur usually in strata forming the caprocks of low mountain ranges.
