limonite, one of the major iron minerals, hydrated ferric oxide (FeO(OH)·nH2O). It was originally considered one of a series of such oxides; later it was thought to be the amorphous equivalent of goethite and lepidocrocite, but X-ray studies have shown that most so-called limonite is actually goethite.
In terms of relative abundance, goethite is second only to hematite (α-Fe2O3) among iron oxides. Goethite is normally formed under oxidizing conditions as a weathering product of iron minerals (e.g., pyrite, magnetite). Because it is formed near the surface, goethite is the major component of the gossan of iron sulfide deposits in locations such as Arizona and of lateritic deposits in places such as Cuba. It also occurs as a direct precipitate in marine and meteoric waters, and deposits accumulate in springs and marshes
Goethite is the source for the pigment known as yellow ochre; it is also the primary mineral in some important iron ores, such as those in the Alsace-Lorraine basin in France. Other important goethite deposits are found in the southern Appalachians, U.S.; Brazil; South Africa; Russia; and Australia.
Goethite varies in colour from yellow-brown to red. It is composed of about 80 to 90 percent Fe2O3 and approximately 10 percent water. When dehydrated, goethite forms hematite; upon hydration, goethite becomes limonite. For detailed physical properties, see oxide mineral (table). .
Hematite, also spelled Haematite, heavy and relatively hard oxide mineral, ferric oxide (Fe2O3), that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance. Its name is derived from the Greek word for “blood,” in allusion to its red colour. Many of the various forms of hematite have separate names. The steel-gray crystals and coarse-grained varieties have a brilliant metallic lustre and are known as specular iron ore; thin scaly types are called micaceous hematite. Much hematite occurs in a soft, fine-grained, earthy form called red ochre or ruddle. Intermediate between these types are compact varieties, often with a reniform surface (kidney ore) or a fibrous structure (pencil ore). Red ochre is used as a paint pigment; a purified form, rouge, is used to polish plate glass.

Baltic Anomaly Looks Like A Crash Site
If that is a crash site why is the channel the UFO created so much smaller that the UFO that created it ?
.
what do you think about the electronic interference experienced while over top of the object? any explanation for that?

A crash site of what? A craft made from stone? I thought we knrw for a long time already it's not a craft but a stone structure of some sorts.
I defiantly concur with that. The very first building material, was stone.

Yes you can make Spacecraft out of granite.Research David Hamel.
