OBSIDIAN IS HOT STUFF Obsidian-bearing volcanoes are typically located in or near areas of crustal instability or mountain building. In North America, obsidian is found only in localized areas of the West, where the processes of plate tectonics have created geologic conditions favorable to volcanism and the formation of obsidian.

- Obsidian is a natural volcanic glass that can be polished to a very high luster. Some stones of obsidian contain white crystals of the mineral cristobalite. When polished these stones produce a gemstone known as snowflake obsidian.he grossularite garnet used to make tumbled stones, beads and carvings is an opaque, massive garnet that often has an attractive green color. Much of it is found in South Africa where it has been inappropriately called Transvaal Jade (it is not jade and has no mineral relationship with jade).

Rocks These distinctions are made on the basis of the types of minerals in the rock, the shapes of individual mineral grains, and the overall texture of the rock. All of these properties indicate the environment, pressure, and temperature in which the rock formed. Granite (left), an intrusive igneous rock, and obsidian (right), an extrusive igneous rock. Both samples are taken from the Sierra Nevada Mountains of California.

OBSIDIAN IS HOT STUFF Obsidian is natural glass that was originally molten magma associated with a volcano. This volcanic glass has an almost total absence of sizable mineral crystals within the glass matrix.

Black Obsidian Stone... Obsidian rock forms from molten lava that cooled very quickly and had no time to form into glass. It is said to be a type of volcanic glass, and is found in a number of places worldwide. There are a number of different variations of this stone, and it comes in a range of types and colors.

Where are Diamonds Found? Diamonds can be found all over the earth however, concentrations of these carbon crystals can form in placer oriented locations (sand and gravel benches) Gold will naturally concentrate in the lowest location in a stream bed, diamonds might. With a specific gravity of 3.5, diamonds are only slightly heavier than rock. If an area is prone to seasonal or flash floods, the most likely location to find diamonds are in the lighter gravels or leading compacted clay benches. Oxbow lakes are another excellent place where concentrations of diamonds can be found. These natural diamond catch areas are found in flood plains and river bottoms.

Obsidian Black is the most common color of obsidian. However, it can also be brown, tan, or green. Rarely, obsidian can be blue, red, orange, or yellow. The colors are thought to be caused mainly by trace elements or inclusions. Occasionally two colors of obsidian will be swirled together in a single specimen.

What is obsidian and how does it form? Obsidian is an extrusive igneous rock, formed from the extremely rapid cooling of felsic lav … a which includes orthoclase, quartz, and mica. Obsidian is a volcanic glass, meaning that the mineral constituents from which it formed did not have time to crystallize due to the rapid cooling.

- Like all glass and some other types of naturally occurring rocks, obsidian breaks with a characteristic conchoidal fracture. This smooth, curved type of fracture surface occurs because of the near-absence of mineral crystals in the glass.The intersections of conchoidal fracture surfaces can be sharper than a razor.ike all glass and some other types of naturally occurring rocks, obsidian breaks with a characteristic conchoidal fracture.

- Obsidian is formed in the Igneous phase of the rock cycle. Its formed as a result of rapid cooling of erupted lava, Obsidian also referred to as Volcanic Glass is an Extrusive Igneous Rock and comes to existence when lava at the earth surface cools at a very fast rate that its crystallization stage hardly comes to play, it appears as a massive rock that is very fine and smooth to touch, and glassy in appearance.

What Is Obsidian? Black is the most common color of obsidian, although it can also often be found in shades of brown and green. If trace elements are present in the rock, it might also take on rarer shades, such as red, orange, yellow, or blue. Obsidian can be found all over the world in areas with volcanic activity.For example, significant deposits of obsidian can be found in the United States, Canada, Mexico, Guatemala, Argentina, Chile, Greece, Hungary, Italy, Iceland, Russia, New Zealand, Japan, and Kenya.lack is the most common color of obsidian, although it can also often be found in shades of brown and green.

- Hike Description. The Obsidian Trail provides an excellent perspective on the many facets of this unique Cascade environment, from dense forests to rugged mountain views, gentle streams to open meadows, lava flows to obsidian cliffs. These cliffs were popular with Native Americans who used the obsidian to craft tools.

Obsidian Obsidian is the rock formed as a result of quickly cooled lava, which is the parent material. Tektites were once thought by many to be obsidian produced by lunar volcanic eruptions, though few scientists now adhere to this hypothesis.

Igneous Rocks The lava coo ls so quickly that no crystals can form. When people make glass they melt silica rocks like sand and quartz then cool it rapidly by placing it in water. Obsidian is produced in nature in a similar way. Obsidian is usually black or a very dark green, but it can also be found in an almost clear form.
