It is usually considered that an integrated ophiolite section is represented by the Troodos ophiolite. Recent study shows that ophiolite sections vary a lot and can be assorted at least into two types. The first type, represented by the Troodos ophiolite, is a thick ocean crust with stratigraphic sequence and is characterized by sheeted dike swarms and thick cumulate unit. The second type, represented by Shuanggou ophiolite, is a thinner ocean crust only with mafic extrusive and intrusive rocks and is characterized by lack of sheeted dike swarms and ultramafic cumulates which may sometimes be poorly developed. Different types of ophiolite sections reflect different dynamic processes under the ocean ridge. It is usually considered that an integrated ophiolite section is represented by the Troodos ophiolite.
