Intrusion igeneous rock Ekstrution Igeneous rock Consists of all material issued to the surface of the earth, both in the land or under the sea surface. This material dg quickly freeze the liquid is thick and which is called lava Teknologi dan Rekayasa The relation between genetic intrution igeneous rock, gang and ekstrution igeneous rock (Katili, 1963) THE EFFUSIVE OF MERAPI MOUNTAIN YOGYAKARTA Quelpuke is a form of a thick extrusion rock Intrution igeneous rock Igeneous Rock : Frozen under the surface of the earth Include : Batholit form Exposed stock form Dyke form Lopolith form Laccolith form Sill form Teknologi dan Rekayasa The form of intrution igeneous rock (AWR potter & H. Robinson Teknologi dan Rekayasa The Block diagram that show the ideal form of lakolith In geology, an intrusion is a rock that has been frozen into a crystal from the melt in the magma under the Earth surface. Magma is frozen below the ground before they reach the surface of the earth called pluton, the name of Pluto, the Roman god of the world underground.
