MobileMT for porphyry exploration - model studies and field examples

open access: yes, 2021
Resistivity methods are an important part of the arsenal of geophysical techniques for the exploration of porphyry-style mineralization. One of the geophysical techniques that could be used to detect the porphyry targets, or its attributes is MobileMT ...

Nature, origin, and phosphorylation potential of the phosphorus/sulfur‐bearing nanoscale multiphasic assemblages in the CM chondrites Murchison and Murray

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 9, Page 2303-2335, September 2026.
Abstract Carbonaceous chondrites contain phosphorus, whose speciation and thus history remain to be investigated. Phosphorus/sulfur‐bearing assemblages have been reported in carbonaceous CM chondrites, but there is no consensus about their exact compositions and origins.

Skarn-porphyry transition: an example from the Antamina skarn, Peru

open access: yes, 2015
It is important to understand skarn-porphyry transitions in order to use exposed skarns to look for associated and potentially larger porphyries. For such purposes, a good start is to understand the transition between porphyry and skarn in known deposits.

The first discovery of a shocked, metasomatised CV3 chondrule‐fragment in a (Al,Cu)‐bearing micrometeorite

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 9, Page 2269-2283, September 2026.
Abstract We report the discovery of the second (Al,Cu)‐alloy–bearing micrometeorite, FB‐A2, recovered from Mount Gariglione (southern Italy), representing the sixth such occurrence worldwide. Although chondritic in nature, FB‐A2 differs markedly from previously described microspherules.

Oceanic anoxic events, subduction style and molybdenum mineralization

open access: yesSolid Earth Sciences, 2016
Nearly half of the world's Mo resources are hosted in Cenozoic porphyries along the east Pacific margin. In contrast, there are essentially no large Mo porphyry deposits along the west Pacific.

Molybdeunum mineralization with emphasis on porphyry systems genesis and exploration [PDF]

open access: yes, 1986
Mo became very important in the last century, because of its sophisticated properties and its use in the new technology of alloys . Porphyry systems (porphyry Cu-Mo and Mo) contribute a significant proportion (90 - 95 per cent) to the Mo world's ...
