Quartz is a good example. Answer: Luster The terms metallic and nonmetallic describe the basic types of luster. Mineral boleh digambarkan sebagai rapuh, mulur, mudah ditempa, sektil, fleksibel, atau elastik. It is a property by which minerals may be described relative to a standard scale of 10 minerals known as the Mohs scale of hardness. Metals and paper are sectile.. Sectility can be used to distinguish minerals of similar appearance, and is a form of tenacity. (13) Our country is abundant in minerals. Mineral preservation Minerals such as orpiment and realgar are sensitive to light and need special storage methods. 2. malleable--if a mineral can be hammered into sheets 3. sectile--if a mineral can be cut into thin shavings with a knife 4. ductile--if a mineral can be drawn into wire 5. flexible--if a mineral is bent but does not resume the original shape 6. elastic--if a mineral bends and resumes the original shape. Nearly all these minerals have a metallic luster, i.e., the peculiar shining appearance of metals, such as gold, silver, copper, lead, tin, iron, etc. Conchoidal: Fractures developed in brittle materials characterized by smoothly curving surfaces, (e.g. Elasticity: Brittle - Uneven: Very brittle fracture producing uneven fragments. Sectility is the ability of a mineral to be cut into thin pieces with a knife. Some minerals tarnish very quickly so that their exterior colour is quite different from the interior colour. Minerals can be described as brittle, ductile, malleable, sectile, flexible, or elastic. The floor of the church is made of opus sectile, a mosaic of coloured marble, and there are some remains of frescoes on the walls. The majority of all minerals are brittle. Learn faster with spaced repetition. Sectile (from the Latin sectilus, a cut): Minerals that can be cut into thin pieces with a knife are sectile.

Famous quotes containing the word examples: " It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people's attention and give them a livelier idea of God than do the often ill-applied examples of his wrath. Their color varies from lead-grey to tin white, may have yellowish or varied tarnish. 117 The opus sectile of the curia of Ilipa (Alcal del Ro, Seville). Sectile minerals can easily be separated into thin slices eg galena Malleable from MINE 224 at University of British Columbia . Sectile:-Mineral which may be cut with knife but slices are not malleable. Metallic minerals, such as copper and gold, are said to be malleable, as they are easily hammered into different forms. Some minerals react when diluted hydrochloric acid is placed on them. Sectile. Brittle - Sectile: Brittle fracture with slightly sectile shavings possible. Examine the methods of each of these concepts through examples, and learn about the usage of the Mohs scale . . These include: color, hardness, diaphaneity, specific gravity, cleavage, fracture, magnetism, solubility, and many more.
