	has antimony content 201 nanogram/gram
structural iron meteorite	has distinguishing feature crystalline iron-nickel alloy
iron meteorite	has relative abundance 5.7 % of meteorite falls
	has weather resistance high
	has fragmentation probability low because it is tougher than stony meteorite
	has ablative mass loss low because it has higher tensile strength than stony meteorite
metal-rich meteorite	has metal content higher than that of average solar system material
differentiated meteorite	has origin planet or asteroid much larger than 100 km in diameter
meteorite	can have crater image
	has impact angle
	has monetary value large if the fall was witnessed
	often produce power outages and failures in electrical equipment due to EMP (electromagnetic pulse)
	can be associated with crater
	vaporizes completely if size is between 3 micrometers and 3 millimeters
	can survive fall if size is larger than 3 mm and velocity is less than 24 km per second
	can survive fall if it fragments because smaller pieces with less mass are more easily slowed by the atmosphere
	can shatter during impact phase
	can fragment during meteor phase
igneous rock	has solidification mechanism
	has solidification timescale
rock	has part mineral
	has texture
	has genesis
