Pyrite: Identifying the Metallic Mineral
Pyrite Characteristics
Pyrite is a metallic mineral that has a bright, brassy yellow color and a metallic luster. It is often referred to as "fool's gold" because of its resemblance to gold. Pyrite is commonly found in sedimentary rocks such as coal and shale, as well as in hydrothermal veins.
Identifying Pyrite Samples
When trying to identify pyrite among different samples, look for its distinctive characteristics. Pyrite has a hardness of about 6-6.5 on the Mohs scale and a specific gravity of 4.95-5.10. It may also exhibit cubic crystal shapes with striations on the surface.
Answer Choices
The sample most likely to be pyrite would be option C. Pyrite's metallic luster and bright yellow color are key indicators in identifying this mineral. By comparing the characteristics of the samples to those of pyrite, you can narrow down the options and make an educated guess.
Explanation: In this case, the answer choice C is the most likely to be pyrite based on its metallic luster and appearance. Pyrite's distinct characteristics make it easily identifiable when compared to other minerals. Remember to carefully observe the characteristics of each sample to determine the correct answer.
