What is the cleavage of onyx?
Onyx like agates is a crypto-crystalline mineral and so it doesn't have any cleavages developed.
The difference between cleavage and fracture?
Cleavage is when you can break the rock into square like pieces and Fracture is when you break a rock into uneven different shaped pieces.
The mineral property texture includes the descriptions conchoidal splintery and irregular?
Sounds like "Fracture"
Is shale fracture or cleavage?
the cleavage is Poor
If you break quartz what physical property?
When quartz is broken it has a conchoidal fracture. Fracture is the appearance of the broken plane of a mineral. A conchodal fracture is described a being curved, and looking like broken glass.
How many cleavage planes forms a silicate sheet?
A silicate sheet mineral like mica has one cleavage plane.
What is the hue or appearance of a mineral?
The definition of hue is color. Appearance could also relate to color, or if the mineral has cleavage or is fractured. Cleavage refers to the formation of a mineral in layers, and fracture is when a mineral has no specific formation pattern. These characteristics are visible. How a mineral appears is what it looks like.
What mineral separates into sheets?
Many minerals separate into sheets. If the mineral has cleavage than it is common for it to separate into sheets. Mica separates into sheets.
A mineral that has uneven surfaces when is said to have?
When minerals break, they can either have fracture of cleavage. Fracture is what you're looking for, and like you said, it's what happens when the mineral breaks and leaves uneven surfaces. A good example of a fractured mineral is quartz. Cleavage, on the other hand, occurs when minerals break along weak atomic bonding planes. Cleavage creates your flatter, more geometric surfaces. Look at mica. It creates what look like sheets of paper due to it's excellent cleavage.
Why do some minerals break by fracturing?
Minerals can have a cleavage plane, multiple cleavage planes, or no cleavage plane. A cleavage plane is an area of weakness in the crystalline structure where the mineral is prone to splitting.
What is the cleavage of onyx?
Onyx like agates is a crypto-crystalline mineral and so it doesn't have any cleavages developed.
A mineral that has uneven surfaces when broken is said to have?
That is referred to as fracturing.
Why does cleavage occur?
Cleavage means to Split.Cleavage is most often used with the following 3 meanings:MITOSIS: a phase during Mitosis when cells split and multiplyGEOLOGY: The splitting of a complex crystal/mineral formation into a simpler oneINFORMAL USE: The viewable split between a woman's breasts
What are the 7 properties mineralogist use to identify ninerals?
Colour - however, this can be a very misleading property. Transparency - Is the crystal transparent, translucent or opaque Lustre - how shiney is the crystal is, there are various different types of lustre. Hardness - Expressed in a number between 0 and 10 on the Moh scale. Streak - the colour of the mineral in powdered form. Easily testable by scratching the mineral on a porcelain plate. Cleavage - Very characteristic to a mineral is what the preferred cleavage is. Mode of occurrence - Is it like needles, fibre, tabular, prismatic, etc.
What Is the tendency of mineral to break into irregular pieces?
This is termed fracture, eg. the conchoidal fracture of obsidian. Breaking into pieces with straight lines and flat faces is called cleavage; minerals like calcite and fluorite exhibit excellent cleavage.
Explain how to identify a mineral using color luster streak hardness cleavage fracture?
Luster is the light reflection a mineral has, which can be broken down into categories like metallic, silky, and dull. The luster dictates what type of mineral it is.
What mineral has a unique property that when burned smells like rotten eggs?
SULFUR
