Appsec 101 Secure Coding The quartz monzonitic intrusion of ‘botro ai marmi’ in tuscany, italy, can be considered to be a typical example of an intrusion centred magmatic hydrothermal system. Copper–gold mineralization associated with potassic alteration occurs in all five intrusions, but the earliest quartz monzonite porphyry intrusion is volumetrically most important and contains the highest ore grade, the highest vein density and the most intense potassic alteration.
Appsec 101 Secure Coding Using the douay intrusion related gold system (irgs) as a type example of neoarchean syenite associated mineralization (abitibi greenstone belt), we demonstrate that zircon from altered quartz monzonite rocks can also be used to infer the age of a magmatic hydrothermal event. Epithermal precious metal deposits form at shallow depths, <1 km. in volcanic arcs, these deposits are linked to deeper porphyritic intrusions and exsolved magmatic fluids. to understand how –. Chalcopyrite and pyrite bearing biotitic breccias emanating from these dikes grade into biotitic veins, indicating that hydrothermal fluids were introduced with dike intrusion about 10 m.y. after emplacement of the butte quartz monzonite. The quartz monzonitic intrusion of "botro ai marmi" crops out on the western edge of the ridge (fig. 2) and is associated with the development of a wide thermometamorphic and metasomatic aureola characterized by the occurrence of marble and skarn.

Copper–gold minerali zation associated with potassic alteration occurs in all five intrusions, but the earliest quartz monzonite por phyry intrusion is volumetrically most important and contains the highest ore grade, the highest vein den sity and the most intense potassic alteration. Here, we present numerical simulations of fluid convection around upper crustal intrusions which explicitly incorporate the feedback between quartz solubility and rock permeability. as groundwater is heated to ~350°c, silica dissolves from the host rock, increasing porosity and permeability. • modelling of the ti diffusion in quartz quantifies the time scales of porphyry deposits. • quartz records a detailed growth history with ti gradients zoning patterns. • individual magma and fluid pulses formed rapidly within tens of thousands of years. •. The fakos quartz monzonite is inferred to be the source of the magmatic component of the mineralizing fluids due to its spatial relationship to hydrothermal veins, which crosscut and emanate from the quartz monzonite.
