What Rock Group Does Obsidian Belong To? A Comprehensive Guide
Obsidian is a naturally occurring volcanic glass that has been used for centuries for various purposes such as tool making, decorative objects, and jewelry. While it may not be an actual rock group per se, it is often associated with minerals and geology. However, if we were to give Obsidian a genre, it would likely be in the metal or hard rock categories due to its dark and sleek appearance.
If you’re a diehard rock music fan who loves to indulge in trivia questions and oddities, you might have stumbled upon this perplexing question – What rock group does Obsidian belong to? The question itself seems cryptic at first glance but rest assured; there’s more than meets the eye.
Before we dive deeper into the answer of this question, let’s get acquainted with what obsidian actually is. Obsidian results from volcanic lava that cools rapidly following rapid cooling or sudden exposure to air or water. It forms through the solidification of silica-rich magma which has little time for crystal growth.
Obsidian is primarily composed of silicon dioxide (SiO2) which explains its glass-like appearance. Due to its composition, it has unique properties such as sharp edges and cleavage planes which make it ideal for cutting tools and blades referred to as “obsidian knives.”
Now back to our initial question – What rock group does Obsidian belong to? As mentioned earlier, obsidian isn’t necessarily part of any specific “rock group.” It can be considered part of the larger category generally known as igneous rocks.
Igneous rocks are formed when magma cools down and crystallizes either on or beneath the earth’s surface. There are two main types of igneous rocks: intrusive igneous rocks (plutonic) which are formed beneath the earth’s surface; obsidian belongs in another type called extrusive igneous rocks (volcanic). I know this sounds like a bunch of geology terms thrown carelessly around; however, trust me on this – it’s interesting stuff.
Now that we know the basics about obsidian and its rock group, how about we go a step further and explore some of the rock bands whose names sound like they include Obsidian? We’re not saying these bands are solely dedicated to the precious volcanic glass. Rather, their names have been inspired by obsidian due to its association with movement, power and strength.

Step-by-Step Breakdown: Identifying the Rock Group of Obsidian
Obsidian is a fascinating volcanic rock that can be found in various parts of the world. Its sharp edges and dark color make it a popular choice for jewelry making and decorative purposes. However, identifying the rock group of obsidian can be tricky if you’re not familiar with its properties. But fear not, as we’ve prepared a step-by-step breakdown to help you through this process.
Step 1: Observe the Physical Characteristics
Obsidian has several physical characteristics that help differentiate it from other similar-looking rocks such as basalt or pumice. The first thing to look for is its color – obsidian typically has a dark black or deep brown hue. It also has an incredibly smooth texture due to its rapid cooling time after being expelled from a volcano. Furthermore, obsidian’s distinctive conchoidal fracture (meaning it breaks in a curved shape like the inside of a clamshell) sets it apart.
Step 2: Conduct Hardness Test
The next step in identifying an obsidian rock is conducting a hardness test utilizing Mohs scale which rates mineral hardness on a scale from 1-10 with softest being talc and hardest diamond (though most common minerals will fall between quartz at 7 and feldspar around 6). Obsidian ranks at about 5 to 5.5 on the scale, proving harder than anything made up of household chemicals but softer than many other rocks including granite.
Step 3: Use Specific Gravity Test
Another way to differentiate obsidian from other rocks is by conducting specific gravity tests where weighing out stones minerals enables researchers determine density based upon their weight-to-volume ratio (mass divided by volume). Obsidian, which formed during volcanic eruptions and subsequent quenching/cooling periods leading less space for trapped gases; boasts higher than average specific gravity – ranging about between 2.4-2.6g/cm³ – hence making it easily distinguishable from heavier rocks.
Step 4: Conduct Chemical Analysis
The final step in identifying the rock group of obsidian is conducting a chemical analysis which helps determine the type of lava it came from. Obsidian is an extrusive igneous rock, which means that it formed as magma erupted from a volcano and cooled quickly on the surface; this process results in high SiO2 (silicon dioxide) content leading to low specific gravity, releasing steam, forming frothy texture instantly captured when cooled swiftly. Different volcanoes produce different types of magma, all with varying amounts of minerals and chemicals –and identifying these can even reveal their geographic origin.
In conclusion, identifying the rock group of obsidian follows four simple steps- observation of its physical properties, its measured hardness score utilizing Mohs Scale; Unique specific gravity examination through weighing/volume ratio and finally chemical composition identification via mineral testing. So next time you come across this striking volcanic glass-like material – you’ll be able to identify it correctly like a pro!

Top 5 Interesting Facts about Which Rock Group Obsidian Belongs To
Obsidian is a rock that has been used for centuries by humans, from making tools to crafting jewellery. But did you know that it also belongs to a particular rock group? Here are the top five interesting facts about which rock group Obsidian belongs to.
1. Volcanic glass
Obsidian is actually considered a volcanic glass and not a mineral because it lacks a crystal structure. It is formed by rapidly cooling lava without sufficient time for crystals to form, resulting in glass-like texture and appearance.
2. Felsic rocks
The group of rocks that Obsidian belongs to is called felsic rocks, which stands for “feldspar” and “silica”. These types of rocks are rich in silicon dioxide (SiO2) and have high levels of aluminum and potassium.
3. Explosively formed
Another fascinating aspect of Obsidian being part of the felsic rocks category is that they are formed under explosive conditions. When volcanic eruptions occur, magma containing felsic materials such as quartz, biotite or hornblende can explode due to gaseous pressure buildup during solidification.
4. Can vary in colour
Obsidian can be found in different colours depending on what minerals the lava contains when it cools down; this variety makes it an attractive material for jewellery makers who search specifically for multi-coloured varieties like rainbow obsidians!
5. Ancient History
Finally, one reason for the popularity of Obsidian throughout history is its use as sharp-edged tools by our ancestors around 8,000 years ago! It was then believed that having accurate cutting tools allowed early humans to survive better as hunters/gatherers.
In conclusion, these are only some fascinating aspects of Obsidian’s classification among felsic rocks such as its explosive origins and its usage among ancient cultures; however with its wide array of colours and unique properties make it an intriguing subject even nowadayss – both for professional practitioners and curious rock enthusiasts alike.
The Role of Geological Processes in Determining Obsidian’sRock Formation and Classification
Obsidian is a volcanic rock that has fascinated people for thousands of years. Its unique properties and striking appearance have made it a prized material in everything from jewelry to weaponry, but what many people don’t realize is just how much the geological processes that formed obsidian play into its classification and properties.
At its most basic level, obsidian is formed when magma cools rapidly, preventing crystals from forming within the rock. This gives obsidian its smooth, glassy texture and black or dark brown coloration. However, there are actually several different types of obsidian, each with their own specific characteristics.
One important factor in determining an obsidian’s classification is the chemical composition of the magma it was formed from. Obsidians can range from being very silica-rich (rhyolitic) to having very little silica (basaltic). Rhyolitic obsidians tend to be lighter in color and more brittle than their basaltic counterparts, which are typically darker and more homogeneous in structure.
Another important factor is the presence or absence of certain minerals within the obsidian. For example, snowflake obsidian gets its distinctive white spots from tiny clusters of crystals (usually feldspar) that form during the cooling process. Mahogany obsidian, on the other hand, contains iron oxide impurities that give it a reddish-brown hue.
All of these factors are determined by various geological processes that occur during the formation of an obsidian deposit. Magma composition can be influenced by things like subduction zones (where one tectonic plate moves beneath another), as well as local topography and geothermal activity. The cooling rate of magma can be affected by factors such as water content and pressure within the volcano where it forms.
Understanding these processes not only helps us classify different types of obsidian; it also sheds light on broader geological phenomena such as volcanic eruptions and plate tectonics. In fact, studying the chemical makeup of obsidian has proven to be a useful tool for geologists researching these and other topics.
So whether you’re admiring a piece of obsidian jewelry or using an obsidian blade to hunt game, take a moment to appreciate the fascinating geological history that helped create this unique material. From magma formation to crystal nucleation and beyond, the story of obsidian is one that’s deeply intertwined with the complex workings of our planet.
