Does halite have cleavage or fracture?
Halite typically displays cleavage along three planes at right angles to each other. However, if halite is subjected to mechanical stress, it can also exhibit a conchoidal fracture pattern due to its brittle nature.
One way to test a mineral is to break it and see how many directions of what it has?
cleavage....
What is the cleavage of dolomite?
Dolomite typically exhibits three cleavage planes that intersect at approximately 90 degrees, resulting in rhombohedral cleavage.
Does galena have a cleavage or a fracture?
It has both. It's cleavage is perfect, and it's fracture is sub-conchoidal.
What is the cleavage of muscovite?
Muscovite has perfect basal cleavage, or book cleavage.
Does halite have cleavage or fracture?
Halite typically displays cleavage along three planes at right angles to each other. However, if halite is subjected to mechanical stress, it can also exhibit a conchoidal fracture pattern due to its brittle nature.
What is sulfurs cleavage cleavage?
Sulfur's cleavage is imperfect.
What do hot spots do?
flood basalts and volcanoes
Why are the crystals in pillows basalts smaller than those in many other examples of basalts?
A factor that determines crystal size in igneous rocks is the speed in which the lava/ magma crystallised or froze. As pillow basalts form at mid ocean ridges where magma is erupted into direct contact with the cold sea water the crystals form very fast and are therefore small. Other basalts erupted on land still have relatively small crystals and crystallised relatively fast but overall slower then pillow basalts.
