  <dc:description>&lt;p&gt;Fractal measurements using the Cantor's dust method in a linear one-dimensional analysis mode were made on the fracture patterns revealed on two-dimensional, planar surfaces in four granites. This method allows one to conclude that:&lt;/p&gt;&lt;ul class="list"&gt;&lt;li class="react-xocs-list-item"&gt;&lt;p&gt;(1)|The fracture systems seen on two-dimensional surfaces in granites are consistent with the part of fractal theory that predicts a repetition of patterns on different scales of observation, self similarity. Fractal analysis gives essentially the same values of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;D&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;on the scale of kilometres, metres and centimetres (five orders of magnitude) using mapped, surface fracture patterns in a Sierra Nevada granite batholith (Mt. Abbot quadrangle, Calif.).&lt;/p&gt;&lt;/li&gt;&lt;li class="react-xocs-list-item"&gt;&lt;p&gt;(2)|Fractures show the same fractal values at different depths in a given batholith. Mapped fractures (main stage ore veins) at three mining levels (over a 700 m depth interval) of the Boulder batholith, Butte, Mont. show the same fractal values although the fracture disposition appears to be different at different levels.&lt;/p&gt;&lt;/li&gt;&lt;li class="react-xocs-list-item"&gt;&lt;p&gt;(3)|Different sets of fracture planes in a granite batholith, Central France, and in experimental deformation can have different fractal values. In these examples shear and tension modes have the same fractal values while compressional fractures follow a different fractal mode of failure. The composite fracture patterns are also fractal but with a different, median, fractal value compared to the individual values for the fracture plane sets. These observations indicate that the fractal method can possibly be used to distinguish fractures of different origins in a complex system.&lt;/p&gt;&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;It is concluded that granites fracture in a fractal manner which can be followed at many scales. It appears that fracture planes of different origins can be characterized using linear fractal analysis.&lt;/p&gt;</dc:description>
