granite and dolerite are examples of which rock

Examples: Limestone and Marble. Granite, Dolerite, Basalt, Trap, are examples. Granite and Dolerite are two examples of intrusive igneous rock. Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. However, if the bubbles are tiny, it’s called pumice. Is Granite an Intrusive or Extrusive Rock. Co Min. two types of host rock, Tjuv-Ante’s Cave represents a unique environment in which to study differences in microbe-rock interactions and speleothem genesis between the granite and dolerite host rock. Form excellent concrete aggregate. Granite Basalt Gneiss Schist Quart-zite Marble Lime-stone Sand-stone Shale Av. In India there are abundant deposits of such rocks in areas like Raniganj, Rajasthan, Bihar, Madhya Pradesh, Tamil Nadu, Karnataka, Meghalaya and Assam. Examples: Granite, Quartzite, Sandstone etc. Our study shows that the mafic rock is superior to the granite in hosting a microbial community and to support formation of speleothems. These rocks are readily acted upon by even dilute HCl. Fig 2: Igneous Rock – Granite ... Dolerite is an example of a hypabyssal rock. Examples of extrusive igneous rocks include basalt, andesite, rhyolite, dacite, obsidian, pumice and scoria. Komatiite is a very rare and old extrusive igneous rock. Some cool so quickly that they form an amorphous glass. • Introduction • Mineralogy • Textures • Classification of dolerite • Dolerite dyke • Formation of dolerite • Distribution • Uses • Conclusion 2. Examples of intrusive igneous rocks are: diabase, diorite, gabbro, granite, pegmatite, and peridotite. If the solidification of the rock occurs near to the earth surface, then the rocks obtained are known as volcanic rocks. Co Range No. Calcareous rocks have calcium carbonate or lime as their leading constituent. If they erupt from volcanoes onto the surface as lava, they are called extrusive rocks.By contrast, Intrusive rocks are formed from magma that cools underground. Granite is an acid rock. Granite is the best example of plutonic rock. These rocks include: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff. 1. Acid rocks: Igneous rocks containing over 65 per cent of silica. The difference between dolerite and granite. Igneous rocks are those that form via the process of melting and cooling. These rocks possess extremely fine-grained structure. Argillaceous rocks are those which have clay or alumina as the main constituent. • A dolerite is the medium-grained equivalent of a basalt - a basic rock dominated by plagioclase and pyroxene. Granite has a lot of different colors ranging from white to pink. If the intrusive rock cooled underground but near the surface, it is called subvolcanic or hypabyssal, and often has visible, but tiny mineral grains. For instance, if an extrusive rock comes out as glass with large bubbles, it’s called scoria. Granite is quarried for building stone, road gravel, decorative stone, and tombstones. Usually contains one or more dark minerals, which may be mica, pyroxene, or amphibole. This type of rock is also known as plutonic rock. If the bubbles are minimal, the rock is called obsidian. is that “dolerite” is a fine-grained basaltic rock and “granite” is a group of igneous and plutonic rocks composed primarily of feldspar and quartz. Examples: Kaolin, Laterite, Slate etc. A rock mass can also fail in tension, compression or shear. Co Max. An extrusive igneous rocks definition states these rocks form when magma "exits and cools above (or very near) the Earth's surface." Compared with basic rocks, acid rocks are of lighter colour and in coarsely crystalline varieties ; free silica or quartz can be seen without the use of a lens.
