Igneous rocks are those rocks that form out of molten rock. Molten rock is commonly known as magma, although this specifically refers to molten rock below the earth's surface. Molten rock that flows above ground is more specifically known as lava. Magma that solidifies becomes intrusive rock formations, whilst lava becomes extrusive rock. Thus there are two types of igneous rocks, intrusive ...

Igneous Rock Texture. If magma cools slowly, deep within the crust, the resulting rock is called intrusive or plutonic. The slow cooling process allows crystals to grow large, giving intrusive igneous rock a coarsegrained or phaneritic texture. The individual mineral crystals are readily visible to the unaided eye. When lava is extruded onto the surface, or intruded into shallow fissures near ...

Amygdular if vesicles have been filled with material (usually calcite, chalcedonay, or quartz, then the term amygdular should be added to the textural description of the rock. An amygdule is defined as a refilled vesicle. Pumiceous if vesicles are so abundant that they make up over 50% of the rock ...

Sedimentary rocks form by breaking down other kinds of rocks into small particles and washing or blowing them away; metamorphic rocks form from other rocks and igneous rocks form by melting other rocks. Thus rocks are always changing form and are redistributted as part of a giant cycle of renewal. This cycle is called the Rock Cycle. (image copied from here) Igneous Rocks: form by ...

Welded Tuffs are extrusive igneous rocks made up of the materials discharged during a volcanic event. The discharged materials fall on the earth's surface after which they lithify into rocks. Welded Tuffs are mostly composed of volcanic ash and at times include large size pieces such as clinkers. 12. Fire Opal . Fire opals are the igneous rocks that are flaming orange or yellow and red in ...

The materials that make up the rocks of the crust are slowly but constantly being changed from one form to another. The interrelationships between rock types can be summarized on what is known as the rock cycle diagram [see p. 28, and the figure to the left]. Magma can either cool slowly (over centuries to millions of years) within the crust—forming intrusive igneous rock, or erupt onto the ...

Also, rocks and beach pebbles too, are composed of minerals. So one could group stones according to what mineral they are made of. Jasper and agate stones belong to the quartz family. But not all stones are composed of only one or two minerals. In that case, a rock or pebble stone will belong to more than one mineral groups.

As we see in Table 2, diabase (dolerite) can be harder than that of most other coarser grained igneous rocks, and as a result it make a good rock hammer. Egyptian quarries are littered with spherical diabase pounders (Klemm Klemm 1993), examples of which can be seen from the Sphinx temple, as well as other places throughout Egypt ( UC27323, UC35981, UC379, UC21411 ).
