Are unakite rocks Sedimentary rocks Metamorphic rocks or Igneous rocks?
Unakite rocks are metamorphic rocks formed from the alteration of igneous rocks. They are typically composed of pink feldspar, green epidote, and clear quartz.
Is emerald an igneous rock?
No, Emerald is a variety of the mineral beryl (Be3Al2(SiO3)6,) colored green by trace amounts of chromium and sometimes vanadium and not an igneous rock. However beryl crystals form in association with Granite intrusions (which are Igneous rocks) and are often associated with tin and tungsten ore bodies in what are called pegmatities. They are also to be found in mica schists which are metamorphic rocks and also uniquely, the emerald deposits in Colombia Colombia are in limestone, a sedimentary rock.
Is epidote an igneous rock?
Epidote is not an igneous rock; it is a mineral that typically forms in metamorphic rocks and is sometimes found in igneous rocks as an accessory mineral. It is often associated with the alteration of plagioclase feldspar and can occur in high-grade metamorphic environments. Epidote is known for its distinctive green color and is commonly used as a gemstone.
Is hornblende an igneous rock?
No, hornblende is a mineral commonly found in igneous rocks such as basalt and granite, but it is not a rock itself. Hornblende is a type of amphibole mineral that is typically dark green to black in color and is a common component of many igneous rock formations.
What is the color of the sedimentary rock?
black

What is the best way to identify if a rock is sedimentary igneous or metamorphic?
sed- cobbles, porus, rub off n cums off, defenite layers met- distorted structure, not smooth, diff color lines, banding in some, sum r green ign- smooth, random intergrown crystals, pumice and scoria are vesicular
How do you determine if a rock is igneous sedimentary or metamorphic?
Speaking in very general terms, and with plenty of exceptions, igneous rock may possess larger visible crystals (granite), may be glassy (obsidian), may have air pockets or bubbles present (pumice), and may be dark green or black-ish (basalt). Sedimentary rock may display sediment layers (like shale), may contain fossils (fossiliferous limestone), and may be fine grained (chemical limestone). Metamorphic rock may display foliation (parallel layers of light and dark minerals)(like gneiss), may have a wavy appearance to the foliation, have platy cleavage, or sparkle from the mineral mica (mica schist).
What type of rock is unakite?
it is ether metamorphic or igneous but I'm pretty sure its a metamorphic rock
What types of rocks are found in Seattle Washington?
There are many types of rocks that are found in Washington state. The most common ones found are sedimentary rocks and metamorphic rocks.
Is hornblende an igneous rock?

How do you tell if a rock is sedimentryigneousand medimorphic?
There is more than one way to answer your question, and if you are given a hand sample (like a chunk of rock) sometimes its hard to tell! Here are some hints that can lead you figure out if a rock is sedimentary, igneous, or metamorphic If a rock is sedimentary: it will be composed of grains, or clasts, from other rocks. Sandstones, for example, will be made up of primarily sand grains. Siltstones, clay stones, or grainstones, will have smaller grains that you might not be able to see with the naked eye! Often sedimentary rocks are porous, which means they have little holes that can hold fluids, like water. can you rub the rock and feel grains coming off in your hand? you might have a sedimentary rock. Do you see fossils in the rock? Its most likely sedimentary. If a rock is igneous; you need to know what minerals may indicate igneous origin. if the rock is a plutonic igneous rock, it will have large grains, and you will probably see feldspars, biotite, pyroxene, and amphibole. Volcanic rocks will be finer grained, so you need to look for structures and textures that would indicate a volcanic origin. If the rock is massive, i.e, no orientation of grains, and no structures are present, you may have a volcanic igneous rock. If your rock is glassy, like obsidian, you may have a volcanic igneous rock. if your rock has holes in it, like pumice, you may have a volcanic igneous rock If the rock is metamorphic; again, you need to look for certain minerals and structures that could point you to this conclusion. If you see chlorite, a harder green mica, you probably have a metamorphic rock. If the rock looks like a sandstone but isn't porous, you have quartzite, a metamorphosed sand stone. If you see foliation (like paper thin layers, perhaps not linear), or deformation structures (like stretched or deformed crystals) there is a good chance you have a metamorphic rock. While some areas may have more of one type of rock than another area, try not to generalize the area until you know what may be causing these types of rocks.
What is the color of the sedimentary rock?
black
Is green aventurine an igneous rock?
Aventurine is a gemstone variety of quartz characterized by its translucency and sparkly metallic inclusions. Glittery inclusions are typically composed of muscovite mica, which usually results in medium to dark green aventurine stones with a silvery green or blue sheenTo buy Green Aventurine visit :-gemtre.in
What is a agate and how much is it worth?
Agate a quartz stone characterized by visible bands and bright colors. There several varieties of agate, many of which are named according to color or other distinguishing characteristic (i.e. Green Agate, Banded agate, Blue Lace Agate) and/or the location in which it is found (e.g. Oregon Snakeskin Agate, Mexican Lace Agate, Botswana Agate). While it was highly prized in ancient times and throughout history, agate is not considered a precious or rare stone. In raw form, small pieces of agate are generally very inexpensive. However, when sold as a piece of jewelry or decorative item, the price may be considerably higher.
