Which Property Is Most Useful in Mineral Identification

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 capacity of one mineral to scratch another determines its hardness.

Internal arrangement of minerals atoms.

. 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. Most minerals can be characterized and classified by their unique physical properties. Laboratory tests would include chemical analysis of the minerals composition.

The physical properties of minerals are related to their chemical composition and bonding. Color luster streak hardness cleavage fracture and crystal form are the most useful physical properties for identifying most minerals. Geologists identify minerals by their physical properties.

B A streak plate is composed of quartz. Which property is most useful in mineral identification. The half-life for the process 238 U -- 206 Pb is 45109 yr.

Density is a property that each mineral possesses. Minerals are classified on the basis of their chemical composition which is expressed in their physical properties. The minerals Galena and Hematite are illustrated on the next slike Both have metallic lusters and seem heavy for their.

A mineral sample contains 660 mg of 238 U and 160 mg of 206Pb. Luster color streak hardness crystal habit cleavage and fracture and some special properties. This module the second in a series on minerals describes the physical properties that are commonly used to identify minerals.

Base your answers to questions 95 and 96 on the diagram and table below. Hardness The ability to resist being scratchedor hardnessis one of the most useful properties for identifying minerals. For minerals in general which of these is the MOST useful mineral identification property listed.

Color luster streak hardness cleavage fracture and crystal form are the most useful physical properties for identifying most minerals. Other properties -such as reaction with acid magnetism specific gravity tenacity taste odor feel and presence of striations-are helpful in identifying certain minerals. One of the most useful qualities for identifying minerals is their capacity to resist being scratchedor hardness.

Color is readily observable and certainly obvious but it is usually less reliable than other physical properties. Color is readily observable and certainly obvious but it is usually. Which property is most useful in mineral identification.

The physical properties of minerals are related to their chemical composition and bonding. Some characteristics such as a minerals hardness are more useful for mineral identification. Many times a sample does not leave a color streak however or is harder than the streak plate.

Color is the least useful property for identification because it is the most obvious property. Which mineral property is best illustrated by the samples. These include color crystal form hardness density luster and cleavage.

Which property is most useful in mineral identification. CTopaz is harder than a steel file. Hardness and density are generally the most useful properties for identifying minerals.

Some characteristics such as a minerals hardness are more useful for mineral identification. The mineral mica breaks evenly alone flat. Probably the most useful characteristic in mineral identification is the chemical composition.

This color will help to determine the minerals identification. Certain mineral usually break along last surfaces while other mineral break unevenly. The diagrams below represent fractured samples of four minerals.

Use one or two sentences Thank you so much in advance. What is the age of the mineral. This test is very useful for Hematite and Limonite.

Which property is most useful in mineral identification. A hardness B luster C cleavage D streak 95. 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. A hardness B color C size D texture 94. How are Minerals Identified.

This charactristic is due to. D Apatite is softer than a copper penny. Hardness luster color streak specific gravity cleavage fracture and tenacity.

The most useful characteristics of a mineral that can be used in a field study are streak color hardness crystal system luster and color. Other properties might be specific gravity feel taste and reaction to acid. 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.
