“…With Göttingen colleagues, his new verdict is that none of the purported glacial mixtites in central and northern Namibia (Gevers 1931;le Roex 1941) have diagnostic glacial features, except possibly those in the Kaoko Belt, which were not revisited. All are better interpreted, he concludes, as submarine mass-flow deposits, possibly triggered by glacioeustatic changes (Martin et al 1985). Henno's recantation makes for sad reading in light of recent studies by specialists showing unambiguous evidence for dynamic grounded ice in the Chuos (Le Heron et al 2013) and Ghaub (Domack and Hoffman 2011) formations of the Otavi fold belt (Fig.…”

“…Henno's last paper on Damaran geology concerns the mixtites of central and northern Namibia (Martin et al 1985). Cogently, he had previously argued that they were likely to be glacial in origin because undoubted glacial deposits occur in southern Namibia at comparable stratigraphic levels (Martin 1965a, b).…”

“…Contudo os trabalhos de Schermerhorn (1974), Porada & Wittig (1983 a e b), Martin et al (1985) e Eyles & Januszczac (2007) refutaram a influência glacial. Na região de Kaokoveld as intercalações ferruginosas são muito delgadas e ricas em sílica (Martin 1965), não apresentando valor econômico, portanto pouco estudadas.…”

“…Ainda assim as formações ferríferas e seus contextos foram muitas vezes interpretados como depósitos glaciomarinhos (Martin 1965, Preiss 1987, Preiss et al 1993, Klein & Beukes 1993 Quanto à interpretação dos ambientes deposicionais, depósitos interpretados como glaciais vêm sendo discutidos e reinterpretados por diferentes autores ao longo da história dos estudos de sucessões neoproterozóicas (Schermerhorn 1974, Martin et al 1985, Eyles & Januszczak, 2004e 2007. Depósitos tidos como produtos de chuva de detritos e clastos caídos de gelos flutuantes, também podem ser interpretados em contextos de fluxos gravitacionais sem influência glacial.…”
