ТЕКСТ А Igneous Rocks

Igneous rocks have crystallized from solidified magma..

Igneous rocks can be classified in a number of ways and one of them is based on mode of occurrence. They occur either as intrusive (below the surface) bodies or as extrusive masses solidified at the

Earth's surface. The terms "intrusive" and "extrusive" refer to the
place where rocks solidified,

The grain size of igneous rocks depends on their occurrence. The intrusive rocks generally cool more slowly than the extrusive rocks and crystallize to a larger grain size. The coarser-grained intru­sive rocks with grain size of more than O.5 mm called plutonic or abyssal are referred ito as intrusive igneous rocks because they are intruded into older pre-existing rocks. Extrusive or volcanic rocks have even fitier grains, less than 0.05 nun and are glassy.

Exposed igneous rocks are most numerous in mountain zones
for two reasons. First, the mountain belts have been zones of major
deformation. Second, uplifts in mountain belts have permitted
plutonic masses to be formed.

The largest bodies of igneous rocks are called batholiths (Fig. 2).
Batholiths cooled very slowly. This slow cooling permitted large min­
eral grains to form. It is not surprising that batholiths are composed
mainly of granitic rocks with large crystals called plutons. As is
known, granites and diorites belong,to the group of intrusive or
plutonic rocks formed by solidification of igneous mass under the
Earth's crust. Granites sometimes form smaller masses called stocks,
when the occurrence has an irregular ihipe;but smaller dimensions
than the batholiths.

Laccoliths and sills, which are very similar, are intruded be-
tween sedimentary rocks. Sills are thin and they may be horizontal,
inclined or vertical. Laccoliths are thicker bodies and in some cases
they form mountains.

Dykes are also intrusive bodies. They ranges in JhicJmeSs from a few inches to several thousand feet. Dykes, are gerjraify much longer than they are wide. Most dykes occupy cracks and have strai&nt parallel walls. These bodies cool much more rapidly and are commonly fine-grained. For example, granite may occur 4n dykes that cut older rocks.

Pegmatites (quartz, orthoclase and mica) also belong to the
group of plutonic or intrusive rocks. They occur in numerous veins
which usually cut through other plutonites, most often granite, or
adjacent rocks.

Extrusive,igneous rocks have been formed from lava flows which come from fissures to the surface and form fields of volcanic rocks such as rhyolite, andesite, basalt, as well as volcanic ashes and dust, tuff, etc. As a rule, these rocks of volcanic on|in cool rapidly and are fine-grained. It is interesting to note that basalt is the most
