- Lunar and Planetary Science XXXV (2004) Vargeão (26º50’S/52º07’W) is the fourth proven Brazilian crater, formed in Cretaceous basalt flows of the Paraná Basin. This multi-ring complex astrobleme has a diameter of 12 km, with a 3 km wide central up-
lift where Jurassic-Triassic sandstones (Botucatu/Pirambóia Fm.) are exposed. Deformation features recognized by [10] and [11] include monomict and polymict breccias of basalt/diabase and sandstones, shatter cones in basalt and sandstone, and PDFs in quartz and feldspar in sandstone.

Обзор статей (из РЖ ВИНИТИ "Геология и геофизика"):
Сообщение об обнаружении и параметрах новых астроблем на
северо-востоке Бразилии, крупнейшими из которых являются Araguainha
(диаметр 40 км), Cangaiha (12 км), Colon (3 км), Riachao (4 км), S. M.
Tapuio (25 км), S. Marta (12 км) Vargeao (12 км). Также обнаружены
структуры Picos, B. Jesus, S. P. Crentes, A. Turiaqu, A. Araguaia, E.
Martins и Bandeira. По морфологическим, петрологическим и структурным
аспектам Araguainha, Cangaiha, S. M. Tapuio и S. Marta отнесены к
меторитным кратерам
(Castelo Branco R.M.G., 2000).
