Goethite is found as an supergene oxidizing (weathering) product of many iron minerals. In the near surface, it was an important iron ore mineral developed over banded iron formations. It is found in sedimentary rocks as concretions and was mined from bog ore deposits.

Dec 09, 2020 Iron ore deposits of two kinds occur in Texas in two general areas: magnetic iron ores in the central mineral region and brown ores (limonite, goethite, and hematite) in northeastern Texas. It is typically formed under oxidizing conditions as a weathering product of iron-bearing minerals, through inorganic chemical or organic precipitation.

Goethite: The mineral goethite information and pictures

Goethite is a common mineral, and is a frequent matrix material for other more aesthetic minerals. It is usually a dark, uninteresting mineral, though specimens from a handful of locations (especially Colorado) are remarkable for their delicate and beautiful crystal growths and velvety botryoidal growths. Goethite is also frequent as black crystal sprays that form within geodes on drusy Quartz.

Mineral deposit Iron deposits Britannica

European oolitic iron deposits, commonly called Minette-type deposits, contain ooliths of siderite, a siliceous iron mineral known as chamosite, and goethite. The deposits were formed in shallow, near-shore marine environments and are most extensively developed in England, the Lorraine area of France, Belgium, and Luxembourg.
