Is onyx a sedimentary metamorphic or igneous rock?
Onyx is a variety of quartz, usually with a sedimentary origin.
A type of metamorphic rock in which mineral grains grow and rearrange but do not form layers?
Non-foliated metamorphic rock, such as marble or quartzite, is characterized by the absence of visible layering or banding. The mineral grains in these rocks recrystallize and grow in a uniform manner, without forming distinct layers like in foliated rocks. This type of metamorphism typically occurs under conditions of high pressure and temperature without the presence of directed stress.
What is the weakest type of rock?
The weakest type of rock is generally considered to be shale, which is a fine-grained sedimentary rock composed of clay minerals. Shale is prone to breaking apart easily and has a low resistance to weathering and erosion compared to other types of rock.
Non- rock has interlocking grains with no specific pattern?
Non-foliated rock, such as marble, has interlocking grains with no specific pattern due to the recrystallization process that occurs under high pressure and temperature, obscuring any original texture or layering. This results in a homogeneous, fine-grained appearance without distinct foliation or banding.
What type of rock is hornfels?
Hornfels is a metamorphic rock that forms from the heat and pressure of tectonic processes acting on existing rocks such as shale, basalt, or sandstone. It is typically fine-grained and can have a variety of mineral compositions depending on the original rock type that underwent metamorphism.
What type of metamorphic texture has no banding?
No banding or alignment of a metamorphic rock's minerals would be consider non-foliated.
Is a metamorphic rock with no banding a nonfoliated rock?
Yes, a metamorphic rock with no banding is classified as a nonfoliated rock. Nonfoliated rocks do not exhibit the layering or banding commonly seen in foliated rocks due to the recrystallization process they undergo during metamorphism.
What type of rock do you fine fossils?
fossils are fine in metamorphic rock
Which kind of metamorphic rock is massive and has no banding?
Marble is a metamorphic rock that is massive and lacks banding. It forms from the recrystallization of limestone and is composed mostly of the mineral calcite. Marbles are often used in architecture and sculpture due to their aesthetic qualities.
What type of rock is pumice?
It is an igneous (volcanic rock).
What is the type of rock that is formed by fine particles?
Siltstone.
What is metamorphic rock with flattened band patterns?
Metamorphic rock displaying banding is referred to as foliated metamorphic rock.
What is a foliated dense rock that has light and dark colored banding?
Gneiss
What type of rock is a stiltstone?
Siltstone is a fine-grained sedimentary rock consisting of consolidated silt.
Type Of Crystal that forms when molten rock cools quickly?
fine
What type of rock would granite turn into if exposed to heat and pressure?
Granite, a type of igneous rock, can metamorphose into gneiss when exposed to high temperatures and pressure. Gneiss is a foliated metamorphic rock with distinct layers or banding due to the rearrangement of minerals under heat and pressure.
Basalt is an example of a n?
Basalt is known as a type of rock. This rock is a dark-colored and fine grained.
