We call that particular tabular mineralization the “sandwich-style” model. Three basic parameters of these deposits are: A) Hydrothermal alteration and mineralization are hosted in permeable pyroclastics bound by impermeable rocks. B) Mineralizing fluids migrated along concentric and radial fractures in the volcanic edifice. C) Hydrothermal convection cells were active for a few thousand years ...

Maria Alejandra earned her B.S Honors in Geology from the Univesidad Nacional de Colombia at Bogotá. She is currently a 4th-year PhD student at the University of Michigan working with Adam Simon. She investigates the origin of structurally and lithologically controlled iron oxide - copper - gold (IOCG) and iron oxide - apatite (IOA) hydrothermal mineral deposits. She focuses on geochemical char...

In the northern of the Sierra de Santa Marta, IOCG-IOA mineralization features have never been reported in Colombia. In a zone where anorthosites were mapped, light and dark rocks were found, with dark gray specks, lenses and sheets or bands; composed by plagioclases with mafic minerals, ilmenite, magnetite and apatite; with granular textures, in parts porphyry-aphanitic; and sedimentary eviden...

Phengite is the main potassic dioctahedral mica identified at the Olympic Dam iron oxide-copper-gold (IOCG) deposit, South Australia, where its mineral chemistry is quite variable. These differences can be explained by contrasting degrees of hydrothermal alteration. In the heavily-sericitized, ore-bearing rocks, the phengites display a lower-Si content, a higher-Al content, and a lower Mg-numbe...

A successful exploration implies to have very clear the characteristics that present the hydrothermal alteration that is associated to these deposits, because it is very important to recognize its alteration-mineralization features and at the same time to take into account the different "pathfinders" that reflect the porphyry type mineralization that can be outcropping or hidden. Within the cha...

Australia is well-known for its beautiful beaches, great views, and kangaroos, but also for its mineral wealth, the early recognition of its mineral prospectivity was held in 1848, the first discovery of Gold in the country, now called the Goldfields region. In 2016, Australia was the top producer for iron ore, bauxite and lithium, and it is second producer of Gold in the world, and the top of ...
