Which Property Is Most Useful in Mineral Identification

Therefore it is the least useful in identifying minerals as. Click to see full answer Hereof which properties of minerals are most useful for identification.

Earth Materials Mineral Identification Historical Geology

In the field where geologists may have limited access to advanced technology and powerful machines they can still identify minerals by testing several physical properties.

. These include color crystal form hardness density luster and cleavage. The physical properties of minerals are related to their chemical composition and bonding. Certain mineral usually break along last surfaces while other mineral break unevenly.

Other properties might be specific gravity feel taste and reaction to acid. Specific gravity Massair Massair - Masswater where Massair is the mass of the mineral in air and Masswater is the mass of the mineral as it is suspended in water. Which property is most useful in mineral identification.

Hardness and density are generally the most useful properties for identifying minerals. CTopaz is harder than a steel file. B A streak plate is composed of quartz.

The capacity of one mineral to scratch another determines its hardness. Geologists identify minerals by their physical properties. Hardness The ability to resist being scratchedor hardnessis one of the most useful properties for identifying minerals.

Some characteristics such as a minerals hardness are more useful for mineral identification. Color is one of the physical properties of minerals and is considered when identifying minerals. Some characteristics such as a minerals hardness are more useful for mineral identification.

Mineral sample 5Mohs scale would be most useful for A resistance to breaking Bresistance to scratching C specific heat D specific gravity 6Mohs scale arranges minerals according to their relative A An iron nail contains fluorite. Probably the most useful characteristic in mineral identification is the chemical composition. Minerals are classified on the basis of their chemical composition which is expressed in their physical properties.

The most useful characteristics of a mineral that can be used in a field study are streak color hardness crystal system luster and color. Hardness luster color streak specific gravity cleavage fracture and tenacity. Same type of mineral can vary in size.

Identify the electrical properties of materials that are highly conductive and those that are used in insulation. Density is a property that each mineral possesses. However color should not be used as a major characteristic of identifying mineral.

Other properties -such as reaction with acid magnetism specific gravity tenacity taste odor feel and presence of striations-are helpful in identifying certain minerals. The minerals Galena and Hematite are illustrated on the next slike Both have metallic lusters and seem heavy for their. In general density and hardness are the most useful properties for identifying minerals.

Color and crystal shape are less useful. The physical properties of minerals are related to their chemical composition and bonding. The half-life for the process 238 U -- 206 Pb is 45109 yr.

Many times a sample does not leave a color streak however or is harder than the streak plate. Some minerals are so alike to each other in other properties that the only way to tell them apart is by doing a specific gravity test. Color is the least useful property for identification because it is the most obvious property.

This module the second in a series on minerals describes the physical properties that are commonly used to identify minerals. Laboratory tests would include chemical analysis of the minerals composition. Color luster streak hardness cleavage fracture and crystal form are the most useful physical properties for identifying most minerals.

Luster color streak hardness crystal habit cleavage and fracture and some special properties. Internal arrangement of minerals atoms. This test is very useful for Hematite and Limonite.

How are Minerals Identified. What is the age of the mineral. D Apatite is softer than a copper penny.

Color is readily observable and certainly obvious but it is usually. For minerals in general which of these is the MOST useful mineral identification property listed. Color is readily observable and certainly obvious but it is usually less reliable than other physical properties.

Which properties were most useful for identifying minerals. A mineral sample contains 660 mg of 238 U and 160 mg of 206Pb. One of the most useful qualities for identifying minerals is their capacity to resist being scratchedor hardness.

The mineral mica breaks evenly alone flat. Most minerals can be characterized and classified by their unique physical properties. Color luster streak hardness cleavage fracture and crystal form are the most useful physical properties for identifying most mineralsOther properties-such as reaction with acid magnetism specific gravity tenacity taste odor feel and presence of striations-are.

This charactristic is due to. Which property is most useful in mineral identification. Use one or two sentences Thank you so much in advance.

This color will help to determine the minerals identification.
