Rutile is found in granite, granite pegmatites, gneiss, mica schist, metamorphic limestone, and dolomite. It may be present as an accessory mineral in the rock, or in quartz veins traversing it.
Hematite can occur in various habits, such as slender crystals penetrating quartz, and as black sands associated with magnetite, zircon, and monazite. Steel-gray crystals and coarse-grained varieties with a brilliant metallic luster are known as specular hematite while petal-like arrangements are called iron roses.
this one looks kinda like a space ship meant to not cause alarm in stone age civilizations. but it should probably arrive at night...
Another example of nature providing wilder things than we can imagine. Crazy geometric objects growing from the ground
ROCKY!
Or a space ship that had a rather rough emergency landing

Holy cow, that's cool!!
I've always adored hematite. No idea why, maybe just something about the shiny darkness.
