One Direction font
One Direction. Definetly One Direction
Liam Payne starts all the One Direction songs
it means that they like this girl and she has thing one thing that stands out about her that makes one direction like her but one direction doesnt know what that one thing is
Mica minerals have only one direction of cleavage. Examples are Muscovite and Biotite.
Perfect in one direction but often does not show.
talc's cleavage is perfect in one direction, basal.
Yes, it is perfect in one direction, basal.
One that has only one cleavage direction will only fracture in one direction/angle to the matrix of the rock. One that only has fracture would fracture in no specific direction and is probably something like obsidian, which fractures conchoidally, like glass.
Biotite (black mica) and muscovite (white mica) are both minerals that have perfect basal cleavage--one direction. It cleaves into thin sheets. Feldspars (albite, oligoclase, andesine, labradorite, bytownite, anorthite) have good cleavage in two directions at nearly right angles, poor in a third direction.
Cleavage is a mineral's tendency to break along flat, parallel surfaces (cleavage planes). Excellent cleavage direction reflects light in one direction, it is considered basal, or book cleavage. Biotite and muscovite have excellent cleavage. Good cleavage reflects light in one direction from a set of many small flat surfaces, augite and gypsum are examples. Poor cleavage directions reflect light form surfaces that are hard to detect, and this is true for sulfur.
Serpentine is a general name for 5 different minerals. These are antigorite, clinochrysotile, lizardite, orthochrysotile, and parachrysotile. Antigorite and lizardite have cleavage in one direction. The others have fracture.
Muscovite mica has perfect cleavage in one direction. It splits into thin sheets.
