In this section we review the early literature on “beef” and “cone-in-cone”, explaining what t… 展开

We have compiled a catalogue of worldwide localities, where beef or cone-in-cone occur in bedding-parallel layers (Cobbold et al., 2012). Where the fibres consist dominant… 展开

Also at the surface, or in boreholes, we have recorded 30 localities, where beef consists of gypsum fibres (Table 1, Fig. 2B), or exceptionally of anhydrite fibres (Machel, 1985). … 展开

At the surface and in deep mines, we have recorded 17 localities, where bedding-parallel layers consist mainly of fibrous quartz (Table 1, Fig. 2C). Typically the fibres are severa… 展开

At intermediate temperatures (150 °C–250 °C), calcite and quartz may precipitate almost simultaneously from aqueous fluids, accounting for bedding-parallel veins of hybrid nature (e.… 展开
