What is a light colored rock with a high silica content?
A light-colored rock with high silica content is likely to be quartz. Quartz is a common mineral that is made up of silicon and oxygen atoms. It can vary in color but is commonly found in light shades such as white or clear.
What rock has more silica granite or basalt?
Granite has more silica than basalt. Granite is a light-colored, coarse-grained igneous rock made up of quartz, feldspar, and mica, which are minerals rich in silica. Basalt, on the other hand, is a dark-colored, fine-grained igneous rock with lower silica content compared to granite.
Would you expect a light gray igneous rock to be rich or poor in silica?
I would expect a light gray igneous rock to be rich in silica. Light gray color in igneous rocks is often associated with high silica content, which is typical of felsic or granitic compositions.
What is a dark colored low silica rock?
Basalt is a dark-colored, low-silica igneous rock commonly found as a result of volcanic activity. Its composition typically contains around 50% silica, making it relatively low in silica compared to other igneous rocks like granite.
Is gabbro a felsic rock?
No, gabbro is not a felsic rock. Gabbro is classified as a mafic rock due to its dark color and high content of iron and magnesium minerals, while felsic rocks are light-colored and have a higher silica content.
What is the rock that has high silica and light colored other than granite?
quartzite
What is A light colored igneous rock with high silica context explosive eruptions?
majority
What is a light colored rock with a high silica content?
A light-colored rock with high silica content is likely to be quartz. Quartz is a common mineral that is made up of silicon and oxygen atoms. It can vary in color but is commonly found in light shades such as white or clear.
A light colored igneous rock with silica content and explosive eruptions?
The rock is likely rhyolite, which is a light-colored igneous rock with high silica content. Rhyolitic magma is viscous and tends to trap gas, leading to explosive eruptions with ash and pyroclastic flows. The high silica content of rhyolite contributes to its light color and explosive nature.
What is light colored ofrten intrusive igneous rock containing a high percentage of silica are called?
felsic
When silica is in a rock does it make it lighter or darker?
Generally, igneous rocks with more silica are lighter in color.
Granite jigneous rocks are light-colored lower in density thank basltic rock and high in silica content?
Yes
What color will igneous rock with high levels of silica be?
An igneous rock with a high level of silica will have a light color.
Is and igneous rock low in silica dark colored or light colored?
Generally, igneous rocks that are low in silica are dark relative to those that are high in silica. This tendency is largely the result of rocks low in silica having increased iron. Iron minerals tend to adsorb significant amounts of the visible spectrum and hence appear dark. I want to emphasize that this is a general tendency and there are exeptions -- obsidian which is very high in silica is typically a dark to black rock and a special igneous rock call carbonatite is very light in color but has little silica.
What rock has more silica granite or basalt?
Granite has more silica than basalt. Granite is a light-colored, coarse-grained igneous rock made up of quartz, feldspar, and mica, which are minerals rich in silica. Basalt, on the other hand, is a dark-colored, fine-grained igneous rock with lower silica content compared to granite.
What is a dark-colored low silica rock?
Mafic igneous rocks, like basalt, are dark colored and low in silica.
What rock forms from light-colored lava?
Rhyolite is a common rock that forms from light-colored lava. It is composed mainly of silica-rich minerals such as quartz and feldspar, giving it a light color. Rhyolite has a fine-grained texture and often contains small crystals.
