Which minerals can scratch glass has a non-metallic luster has fracture and is a dark red color?
A mineral that can scratch glass, has a non-metallic luster, exhibits fracture, and is dark red in color is likely garnet, specifically varieties like almandine. Garnet typically has a hardness of about 7.5 to 8 on the Mohs scale, allowing it to scratch glass, and it often displays a vitreous to resinous luster. Its dark red hue and tendency to fracture rather than cleave further support this identification.

What does a mineral with a nonmetallic silky luster have?
A mineral with a nonmetallic silky luster is likely to be fibrous in structure, such as asbestos or satin spar gypsum. This type of luster is caused by the arrangement of fine parallel fibers that reflect light, creating a smooth and shiny appearance. Minerals with this luster are often valued for their unique texture and appearance.
What are three types of mineral luster?
Metallic luster: minerals that have the appearance of polished metal, such as pyrite or galena. Vitreous luster: minerals that have a glassy appearance, like quartz or feldspar. Pearly luster: minerals that exhibit a soft, pearl-like sheen, such as talc or gypsum.
What are common nonmetallic minerals?
Common nonmetallic minerals include quartz, feldspar, mica, calcite, and gypsum. These minerals are often used in various industries; for example, quartz is widely used in glass production, while gypsum is essential in making drywall. Nonmetallic minerals typically lack metallic luster and are valued for their physical properties rather than for metal content. They play critical roles in construction, manufacturing, and agriculture.
What are the seven characteristics used to identify minerals?
The seven characteristics used to identify minerals are color, streak, luster, hardness, cleavage, fracture, and specific gravity. These properties can help differentiate one mineral from another based on their unique physical and chemical properties.
What mineral has a pearly luster and a conchoidal fracture?
The mineral that has a pearly luster and a conchoidal fracture is talc. Talc is a soft mineral with a characteristic pearly luster due to its perfect cleavage planes and breaks with a unique conchoidal fracture pattern.
What mineral can scratch glass has a nonmetallic luster has fracture and is a dark color?
The mineral that fits these descriptions is obsidian. Obsidian is a natural volcanic glass that can scratch glass, has a nonmetallic luster, typically exhibits conchoidal fracture, and is usually a dark color, such as black, dark green, or dark brown.
Is calcite metallic or nonmetallic?
Calcite is a compound and therefore cannot be classified as a metal or nonmetal.
What mineral has nonmetallic luster and it is black?
There is not enough information to go on. Many minerals fit this description, especially since there are several types of nonmetallic luster.
What is the most common type of nonmetallic luster?
The most common type of nonmetallic luster is called "vitreous" luster, which resembles the appearance of glass. Minerals with vitreous luster reflect light in a way that gives them a shiny and somewhat transparent look. Other types of nonmetallic luster include pearly, silky, and dull, but vitreous is the most frequently observed in various minerals.
Metallic submetallic and nonmetallic are descriptions of a mineral's?
Luster. It describes how a mineral reflects light and can be used to distinguish different minerals based on their appearance. Minerals with a metallic luster appear shiny like metal, those with a submetallic luster are somewhat shiny, and those with a nonmetallic luster do not appear shiny.
What is nonmetallic luster?
Nonmetallic luster refers to a dull or earthy appearance of a mineral or material that lacks the shiny or reflective properties of metallic luster. Nonmetallic luster can be described as having a matte, powdery, or waxy finish, often seen in minerals like talc or graphite.
What mineral is nonmetallic and has a silky luster?
The mineral that is nonmetallic and has a silky luster is serpentine. Serpentine is a group of minerals that are typically green in color and have a silky or waxy sheen on its surface. It is commonly found in metamorphic rocks.
What is one property that may be used to digstinguish metallic from nonmetallic minerals?
One property that may be used to distinguish metallic from nonmetallic minerals is their luster. Metallic minerals tend to have a shiny, reflective surface due to their metal content, while nonmetallic minerals have more of a dull or earthy appearance.
Which property categorizes minerals as either metallic and nonmetallic?
The property that categorizes minerals as either metallic or nonmetallic is their luster. Metallic minerals exhibit a shiny, reflective surface that resembles metal, while nonmetallic minerals have a dull, glassy, or earthy appearance. This distinction helps in identifying and classifying minerals based on their physical characteristics and potential applications.
What does a mineral with a nonmetallic silky luster have?
A mineral with a nonmetallic silky luster is likely to be fibrous in structure, such as asbestos or satin spar gypsum. This type of luster is caused by the arrangement of fine parallel fibers that reflect light, creating a smooth and shiny appearance. Minerals with this luster are often valued for their unique texture and appearance.
What are whitish-gray stones with a nonmetallic luster that leave a colorless streak?
Whitish-gray stones with a nonmetallic luster that leave a colorless streak are likely to be varieties of minerals such as quartz or feldspar. These minerals often exhibit a light color and can be found in many geological environments. Their nonmetallic luster and ability to leave a colorless streak are characteristic features used to identify them in mineralogy. Further examination, including hardness and crystal structure, would help in precise identification.
What is metallic miner?
Metallic minerals are minerals that have a metallic luster, making them very shiny. A few metallic minerals are Graphite, Galena, Magnetite, and Pyrite. The mineral Hematite can be metallic or nonmetallic
