ResumenLos depósitos de Pb-Zn-Cu-Ba-F-Sr epigenéticos estratoligados en series sedimentarias han constituido una de las mayores fuentes de metales en la historia de la humanidad. Aún en la actualidad continuan siendo un objetivo prioritario de exploración para las compañias mineras, debido tanto a su fácil metalurgia como a los grandes tonelajes que presentan los distritos clasifi cados bajo esta tipología.En México existen todo un conjunto de mineralizaciones de Pb-Zn-Ba-F que han sido sistemáticamente consideradas como pertenecientes a tipologías diversas (skarns, reemplazamientos de alta temperatura, epitermales, etc.) que, bajo una nueva pespectiva, responden a un modelo de circulación de fl uidos de cuenca enriquecidos en metales, fl úor y bario durante su tránsito por la serie sedimentaria. Estos fl uidos han dado lugar a un conjunto de cuerpos mineralizados estratoligados que aparecen encajonados dentro de las series de plataforma carbonatada mesozoicas del centro, N y NE de México. Típicamente, no están asociados genéticamente a magmatismo alguno, no causan una alteración muy acusada en la roca encajonante, suelen estar asociados a la presencia de materia orgánica (hidrocarburos líquidos, bitúmen), presentan una mineralogía muy sencilla, a menudo casi monominerálica (barita, celestina, fl uorita, esfalerita, galena) y suelen presentar temperaturas de formación dentro del rango de 90-150 °C con salinidades variables. Todo este conjunto de características hacen a estos depósitos plenamente comparables con los MVT del subtipo Alpino-Apalachiano.En este artículo se lleva a cabo una revisión sobre el conocimiento que se tiene sobre este tipo de depósitos a nivel global para, después, pasar a discutir la presencia de esta tipología en suelo mexicano y sus características geológicas y geoquímicas más relevantes.Palabras clave: Depósitos de tipo MVT, generalidades, geoquímica, depósitos en México, estado del arte. AbstractThe low temperature, epigenetic and stratabound Pb-Zn-Cu-Ba-F-Sr-bearing ore deposits enclosed within sedimentary series have been one of the major sources of metals in history. Presently, exploration companies still fi nd these deposits

The stratabound mineralisation, believed to result from intensive replacement of evaporites, is structurally controlled by a set of conjugate, extensional, north‐northeast, oblique‐slip faults, and shows signs of multiple brecciation and precipitation (Tompkins et al . 1994; Dorling et al .…”

Australia produces more than 22 mineral commodities from a wide variety of deposit types, but >90% of the value of mine production is obtained from just 10 commodities. Both production and resources are underpinned by a few major deposit classes and a small number of world‐class deposits. Most major deposits lie in highly endowed metallogenic provinces and formed at discrete intervals during major metallogenic epochs, notably: 2.7–2.6 Ga, 2.4–2.2 Ga, 1.7–1.6 Ga, 1.2 Ga, 500–480 Ma, 440–420 Ma, 380–350 Ma, 320–280 Ma, 240–220 Ma and 100–0 Ma. These lie within the global metallogenic epochs that have previously been shown to coincide with the accretion and breakup of the major continents. Many of the major metallogenic provinces formed by accretion during convergent tectonic regimes and can be linked to particular orogenic events and/or changes in the apparent polar wander path. Giant deposits appear to have formed from large systems commonly located at major crustal structures. The interplay of source, transport and trap is critical. Formation of ore bodies occurs when hydrothermal fluids are released in a focused manner, migrate along ‘open’ transport zones, and interact with suitable traps to deposit metals. Typically this occurs late in the tectonic evolution of the province or basin and may be associated with uplift and/or basin inversion. The efficiency of the trap site is a key factor in determining ore‐deposit size, and is enhanced by major physical and chemical contrasts between trap and fluid. Emplacement of mineralised intrusions and migration of mineralising fluids occurs in response to geodynamic triggers involving changes to the stress regime that may include far‐field stresses propagated across the Australian continent. With the exception of supergene deposits, mineralisation typically appears to have occurred within short time frames (<1 million years) in response to the geodynamic triggers. Formulation of the next generation of predictive, geologically credible models requires an integrated, holistic mineral systems approach with a strong focus on crustal architecture and the relative timing of critical events.

“…Tompkins et 01. (17) disputed this conclus~on and suggested that m~nera1i:at~on had occurred not only during subsidence but also during subsequent uplift, and they also suggested that two of the larger deposits (Blendevale and Cadjebut) were geologically younger (325 -t 25 Xla). hlore recently, hon.e~-er, Rb-Sr dating of sphalerite from the Blendevale deposit has indicated an age of 357 -t 3 hla, supporti~lg an earlier mineralization event (7).…”

ceptihility of Sr3CuPtc jIr,,j06 follolvs the predicted behavior of a random quantum spin chain (Figs. 3 and 4). A t high temperatures, the susceptibility has a linear x versus 1/T dependence and is Curie-like. In this regime, where there is 110 ordering among unpaired electrons, the spins act independently. A fit of the high-temperature data ga17e a Weiss constant of 8 = -12.7 K and a spin-only tnotnent of (I, = 2.11 Bohr magnetons. This moment is in excelle~lt agreement with that expected for a sample containing, on a17erage, one S = ?h Cu ion and o~le-half S = lh Ir ion, nhich should yield an effecti1.e moment of (I, = 2.12. A t lon.er temperatures, there is a t r a n sition to a regime where spin-spill interactions hecome important, as indicated by the broad cur17e in the inl~erse susceptibility. This transition marks the alignment of spins to form islands of effecti1.e spins, as discussed above. Comparison of Figs. 3 and 4 sho\vs that theory and experiment are in good agreement.
