Textures Of Rocks

This is a planet texture inspired by the mars surface the mars texture is made using a red rock texture.

Textures of rocks. Phaneritic aphanitic porphyritic glassy pyroclastic and pegmatitic. Texture and structure of igneous rocks. Texture of a rock is the appearance of the rock and how one feels touching it. The texture of a rock provides a clue whether the magma cooled fast or slowly and where the rock was formed.

You can use this planet mars texture to create interesting text effects and typography you can also use it to add texture to a sphere and make a planet in 3d use this mars texture as background for your website or for all kinds of graphic design. The texture of a rock is the size shape and arrangement of the grains for sedimentary rocks or crystals for igneous and metamorphic rocks. There are six main types of textures. Texture or rock microstructure in geology refers to the relationship between the materials of which a rock is composed.

The size and shape of the mineral grains or crystals and the pattern of their arrangement give a texture to the rock. Larger scale features such as fractures and layering are considered rock structures in comparison. Rocks with holocrystalline texture are also termed as phaneric and the holohyaline rocks are referred as aphinitic. Also of importance are the rock s extent of homogeneity i e uniformity of composition throughout and the degree of.

Even if a complex assemblage is not identifiable at the wellsite a combination of minerals and textures should allow the rock to be characterized. The broadest textural classes are crystalline in which the components are intergrown and interlocking crystals fragmental in which there is an accumulation of fragments by some physical process aphanitic in which crystals are not visible to the unaided eye and. The textures are different in intrusive vein and extrusive rocks. Add details to your answers for question 1.

The texture of a rock refers to the details of its visible character. The texture of a metamorphic rock is a unique product of its mineralogy and metamorphic conditions. The term microcrystalline is used for the textures in which the minerals are perceivably crystallized but in extremely fine grain. This includes the size and quality and interrelations of its grains and the fabric they form.

Textures of igneous rocks. The texture of igneous rocks can be analyzed to understand how the rock became solid or crystallized from liquid melted rock. The texture of igneous rocks depends on the composition of the magma and the conditions surrounding the magma s cooling.
