The Parana volcanic province is a window into mantle and crustal processes in the Cretaceous. The variability and complexity of this province can be determined through the study of minerals. An integrated study of zircon from Parana lavas (one high-T

Different hypotheses exist on the origin of native copper mineralization in the Parana volcanic province that invoke magmatic, late magmatic, or hydrothermal events. The average copper content in the host basalts is ~200 ppm. Native copper occurs as

A remarkable sand injectite complex (1 million km2) is hosted in Parana volcanic province, South America, and is here described. Named Novo Hamburgo Complex, these sand injectites originated by the interaction of several major geological processes, a

A new frontier of amethyst geode deposits (amethyst, agate, gypsum, calcite and zeolites) driven by the prospective guide termed silica gossan may change the metallogenetic scenario previously known in the Parana volcanic province. Silica gossans, wh

Thousands of silica gossans are exposed at the top of the Lower Cretaceous basalt hills in the Parana volcanic province, strongly indicating the presence of calcite, amethyst and agate geode deposits along with native copper mineralization. The Embra

Variable intensity of hydrothermal alteration of the Veia Alta basalt flow, Ametista do Sul, Brazil, exerted the fundamental control on the shape and size of the amethyst geodes. The loss on ignition (LOI) of the host basalt is used as a proxy for in

The Serra Geral Group has high Cu concentrations in southern Brazil, including the Realeza (Parana) region where Au and Ag also occur. The basalts (46.7–50.8 wt.% SiO 2 ) have breccias at the top of 10 out of 31 studied flows in the Realeza section

Two fundamental issues in the understanding of processes active at the onset of volcanism in the Parana volcanic province of South America are the description of individual lava flows and the relationships between the lavas and the underlying loose e
