Petrologic significance of Fe-rich staurolite in pelitic schists of the Silgará Formation, Santander Massif

Autor: Ríos R, Carlos Alberto, Castellanos A, Oscar Mauricio

Publikováno v: Earth Sciences Research Journal, Volume: 20, Issue: 1, Pages: 1-7, Published: JAN 2016

Medium grade metapelites of the Silgará Formation at the Santander Massif (Colombian Andes) have been affected by a medium-pressure/high-temperature Barrovian type of metamorphism, developing a sequence of metamorphic zones (biotite, garnet, staurol

Zeolitisation of Neogene sedimentary and pyroclastic rocks exposed in Paipa (Boyacá), in the Colombian Andes: simulating their natural formation conditions

Autor: Ortíz Q, Fredy Alberto, Torres Valenzuela, Johel, Ríos R., Carlos Alberto

Publikováno v: Earth Sciences Research Journal, Vol 15, Iss 2, Pp 89-100 (2011)
Earth Sciences Research Journal, Volume: 15, Issue: 2, Pages: 100-89, Published: DEC 2011

The present study concerns the synthesis of zeolites from Neogene sedimentary and pyroclastic rocks exposed around the Sochagota Lake, Paipa (Boyacá). Two synthesis methods were used: conventional hydrothermal treatment and alkaline fusion followed
