摘要信标组还没有得到充分的定义。本小组各部门的拟议标准部分是根据维多利亚谷地区的堡垒山和堡垒来描述的。在那里，灯塔群有4500英尺厚，分为基底韦伯砂岩，堡垒砂岩和山堡垒煤系。Bastion山煤系的植物微化石年代为二叠纪中期，含有薄的无烟煤煤层，灰分为30%。同一领域的补充章节的详细内容载于附录。
Abstract The Beacon Group has not been adequately defined. Proposed standard sections of divisions of the Group are described from Mount Bastion and the Fortresses in the Victoria Valley region. There the Beacon Group is 4,500 ft thick and is divided into the basal Webb Sandstone, the Fortress Sandstone, and the Mount Bastion Coal Measures. The Mount Bastion Coal Measures are dated by plant microfossils as midPermian, and contain thin seams of anthracite with 30% ash. Details of supplementary sections in the same area are given in an appendix.
