Hematite mainly occurs in cleavage cracks and microfissures of such minerals as feldspar , and the higher the hematite content , the deeper the red color 赤铁矿主要赋存在长石等矿物的解理缝及其显微缝隙中，赤铁矿的含量越多，颜色越红。
Similarly , troughs in valles marineris contain hematite - bearing rocks in fine , easily eroded layers , matching what one expects from deposition in standing water 同样的，水手谷的谷地里也有细致、易受侵蚀并含赤铁矿的岩层，符合我们对静水沉积物的预期。
Based on a brief analysis of the genesis of hematite , the authors hold that hematite in red granite was mostly produced under the condition of high oxygen fugacity 本文对赤铁矿的成因作了简要分析，认为红色花岗岩中的赤铁矿大多为高氧逸度条件下的产物。
Above the glacial layers sits a red sandstone containing hematite ? a mineral that forms only under oxygen - rich skies . ( hematite has also been found at the landing site of the mars rover opportunity 覆盖于冰期地层上方的砂岩，则含有只在含氧丰富的环境中才会形成的赤铁矿（火星巡?者机会号探测车的著陆点亦发现赤铁矿的存在，然因颗粒较粗，故呈灰色。 ）
