									  THE STRUCTURE OF
   IGENEOUS ROCK
Is frozen in the form of rock big
scale, like pillow lava structure in
the environment that sea water,
lava body, flow structure and so
on.
     THE TYPES OF IGENEOUS
        ROCK STRUCTURE
Masif: does not indicate the nature of the flow of gas or impressions,
      or does not indicate the existence of other rock fragments that
      are embedded in the body.
Fillow lava (pillow lava): is a structure that is expressed padabatuan
      ekstrusi particular, characterized by a cushion-shaped mass in
      which the size of the form is generally between 30-60 cm
      distance and near
Joint: the structure is marked by a hefty-hefty arranged in
      perpendicular direction of flow, this structure can be developed
      columnar jointing.
Vesikuler, is a structure that marked the holes with a regular way.
      Hole was due to discharge gas at the time of freezing magma
      progress.
Skoria, such as vesikuler rah but does not indicate a regular
      Amigdaloidal, strutur where the holes filled by a gas discharge
      minerals such as secondary zeolit, carbonic, silica.
Xenolith, the structure shows that there is an incoming rock
      fragments embedded in the rock or frozen. Structure was
      created as a result of the merger is not a perfect bauan
      sampingdi of magma in the breach.
Autobrexia, the structure shows that the lava fragments from the
      lava-fragment itself.
