Limonite is usually the product of such weathering but hematite is also possible (I am assuming you know the difference between martite and hematite). As Alfredo suggested oxygen isotopes should be able to distinguish martite formed at low temp and pressure ( weathering conditions) from that formed hydrothermally.
Brown hematite, or limonite, iron ores were being mined from more than 40 open pits and underground mines.

Pure hematite has a specific gravity of 5.3, so this rock must contain some low-density mineral like quartz or a carbonate in addition to hematite.
'Limonite' is most commonly the mineral species goethite, but can also consist of varying proportions of lepidocrocite, hematite and/or maghemite, along with impurities of other minerals such as quartz and clays.
Hematite occurs in a range of forms, and its color can range from black to gray, or from red to brown depending on which variety is present. ... Goethite (a.k.a. Limonite): Goethite is a hydrous (water-bearing) iron oxide that forms as a direct precipitate in marine water and bogs, and as an alteration of other iron-bearing minerals. Along with ...
Hematite, magnetite, pyrite, and other iron-bearing minerals typically weather to create limonite as a secondary substance. This iron ore in India is also found in small amounts in stratified deposits where hydrous iron …
• Common oxide minerals include: hematite and limonite. Hematite Pronounce: • Hematite, an iron oxide, has a composition of Fe 2 O 3. • Hematite is identified by its non-metallic or metallic luster and its red to red-brown streak. • Its hardness …
Limonite forms in sedimentary beds and from the weathering of metals such as pyrite, magnetite or brown hematite also known as brown iron ore. It is one of the minerals that make up the limonite pseudomorph Prophecy Stone, which is a pseudomorph of Limonite and Hematite after Marcasite or Pyrite.
The experimental results from this work have shown that an efficient magnetic separation of hematite and limonite (weakly magnetic minerals) in the fine size range can be achieved at a middle-intensity if the mineral fines are selectively and strongly aggregated, leading to a great decrease at field intensity and gradient. ...
Hematite and limonite magnetizing roasting can be achieved in two ways: high temperature and low carbon monoxide concentration roasting or low temperature and high carbon monoxide concentration roasting. Low-temperature roasting has some advantages with respect to energy consumption [72]. Another study showed that the gangue minerals in oolitic ...
Porous hematite ore was prepared by the dehydration of low-grade limonite ore with high moisture content. In this study, the mechanisms and kinetics of the isothermal reduction of hematite ore fines by hydrogen–nitrogen gas mixtures were investigated using a rotary drum reactor in the temperature range of 700–900 °C.

The impurity sulfur in lead–zinc-bearing hematite–limonite ore mainly exists in the form of galena, sphalerite, pyrite, and natural sulfur, and deep reduction roasting–low intensity magnetic separation does not effectively remove sulfur in a low valence state, which affects the quality of iron ore concentrate. Thereby, the desulfurization mechanism of the oxidative …

Instead, iron ore nuggets (in the form of hematite, limonite or magnetite nuggets) must be smelted in a bloomery to produce iron blooms, which are further refined on a bronze or better anvil into wrought iron, which can then be smithed into tools. Ores. There are three types of iron-containing ores in the game: hematite, magnetite and limonite.
Hematite's Streak: All specimens of hematite will produce a reddish streak. The streak of a mineral is its color in powdered form when scraped across a streak plate (a small piece of unglazed porcelain used to produce a small amount of mineral powder). Some specimens of hematite will produce a brilliant red streak, others will produce a reddish brown streak.
