Task: Class Definition Understanding (ontology: Earth_Environment/SWEET)

Which of the following definitions best describes 'dike'?

A. A dike swarm or dyke swarm in geology is a major group of parallel, linear, or radially oriented dikes intruded within continental crust. [Wikipedia]
B. A the concept is a large emplacement of igneous intrusive (also called plutonic) rock that forms from cooled magma deep in the Earth's crust. Batholiths are almost always made mostly of felsic or intermediate rock-types, such as granite, quartz monzonite, or diorite (see also granite dome).There is also an important geographic usage of the term the concept. For a geographer, a the concept is an exposed area of mostly continuous plutonic rock that covers an area larger than 100 square kilometers. [Wikipedia]
C. [Pluton] Igneous intrusion - A the concept is a tabular pluton that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or even along the direction of foliation in metamorphic rock. The term the concept is synonymous with concordant intrusive sheet. This means that the the concept does not cut across preexisting rocks, in contrast to dikes, which do cut across older rocks. [Wikipedia]
D. Dikes, long, planar (sheet) igneous intrusions, enter along cracks, and therefore often form in large numbers in areas that are being actively deformed. [Wikipedia]

Answer: Dikes, long, planar (sheet) igneous intrusions, enter along cracks, and therefore often form in large numbers in areas that are being actively deformed. [Wikipedia]
