摘要
海南省坝王岭地区花岗岩分布广泛。通过1:5万区调填图,初步建立了单元、超单元等级体制。其中的雅加超单元是一个高位深成岩体的典型代表,它由南宝岭、分水岭、黑岭三个单元组成,单元之间全为涌动型侵入接触,无截然的岩性分界面,但不同单元间岩性变化明显,岩石结构变化较大。该超单元具套叠式构造特点,是一个以典型的结构演化序列为主所形成的超单元。
Granite is widely distributed in Bawangling Hill area,Hainan Province. Through 1 : 50,000 scale regional geological reconnaissance mapping in Bawangling Hill area, units and superunits of granite are primarily established. Among the super units, Yajia Superunit is a representative of high-seated pluton,and consists of Nanbaoling,Fenshuiling and Heiling Units. The relations between these units are all surge-type intrusive contact. So,there are no obvious boundaries between them,but the lithology and structure are much different from each other. This Superunit is characterized by tepee structure and is a superunit mainly with the typical evolutionary sequence of textures.
