Abstract In Australian stratigraphic nomenclature, the concept of granitic rock suites has been in formal use for over a decade. The basis for this suite classification of granitic rocks is inconsistent and, in eastern Australian usage, unsound on several levels. We also note that the approach used in Western Australia is different. Granitic intrusions are probably not truly amenable to any strict, comprehensive, lithostratigraphic classification. If these rocks are integrated into such a scheme, group- and supergroup-level units (i.e. formal suites and supersuites) should not be incorporated. For the present, mappable units should be recognised at the levels of formation and member. The use of granite suites and supersuites in formal stratigraphic hierarchies is not recommended. Instead, granitic bodies could be grouped into individual plutons, which may or may not form parts of larger batholiths. KEY POINTS The suite-based classification of granitic bodies, as currently used in the Australian Stratigraphic Units Database, is based on unsound principles, and is not employed in a consistent manner. Granitic intrusive rocks probably cannot be grouped using lithostratigraphic principles that are consistent with either the local or international codes. Granitic bodies can be grouped into batholiths, plutons and members, but the names of these units should, for the moment, remain informal.

花岗岩套房：一个有问题的概念？

摘要 在澳大利亚地层命名法中，花岗岩组的概念已正式使用十多年。对花岗岩进行这种组合分类的基础不一致，并且在澳大利亚东部的用法中，在几个层面上都是不合理的。我们还注意到，在西澳大利亚州使用的方法是不同的。花岗岩侵入体可能并不真正适合任何严格、全面的岩石地层分类。如果将这些岩石整合到这样的方案中，则不应包含组级和超组级单元（即正式套房和超级套房）。目前，可映射单位应在编队和成员级别得到认可。不推荐在正式的地层层级中使用花岗岩套间和超级套间。相反，花岗岩体可以分为单独的岩体，它可能会或可能不会构成较大基石的一部分。要点 澳大利亚地层单位数据库中目前使用的基于套件的花岗岩体分类是基于不合理的原则，并没有以一致的方式使用。使用符合当地或国际规范的岩石地层学原理，可能无法对花岗岩侵入岩进行分组。花岗岩体可以分为基岩、岩体和构件，但这些单元的名称目前应该保持非正式。使用符合当地或国际规范的岩石地层学原理，可能无法对花岗岩侵入岩进行分组。花岗岩体可以分为基岩、岩体和构件，但这些单元的名称目前应该保持非正式。使用符合当地或国际规范的岩石地层学原理，可能无法对花岗岩侵入岩进行分组。花岗岩体可以分为基岩、岩体和构件，但这些单元的名称目前应该保持非正式。
