Quarlite tlpe |
Quartz inclusions commonly found are: fat crystal (Hair crystal) - mainly rutile; grass into the crystal - mainly tourmaline; water biliary crystal - quartz inclusions in the liquid; Green quartz - light blue rutile needles containing flakes; Milk quartz - from small holes caused by the turbidity of water-like; Green quartz - or debris from the plate-like composition of chlorite, it may sometimes be of a green needle-like actinolite; sand stone (Aventurine) - quartzite internal containing green or reddish-brown thin film of mica, quartz, also known as Edward, commonly known as Stone Dongling. Common tobacco smoke black to dark brown crystals, mainly because these rocks contain large amount of radioactive uranium, thorium element of the relationship. |
