“…Garside et al (1975) show the increase of the bulk crystal growth with super saturation and the square root of the flow velocity. Theirs experiments show that the variation of the bulk growth rate increase at low velocity and high supersaturation.…”

Estimating the local paleo-fluid flow velocity: New textural method and application to metasomatism. Earth and Planetary Science Letters, Elsevier, 2009, 280 (1-4) Finally, a two-stage tectono-hydrodynamic model is proposed for the metsomatism. The first stage is genetically linked to the sill injection, and the second is characterized by a wider event with hydrothermal flow passing along the leucogranite sills.

“…Similar observations were reported in natural crystal by Kesler et al (1972) for galena in Mississippi Valley type deposits. Several models have been developed in order to study crystal growth and the relation with its environment at bulk crystal scale (e.g., Garside et al 1975) and very local scale (Chernov 1992). Prieto and Amoros (1981) and Sizaret et al (2006) analyzed the relationship between flow velocity and growth rate of faces with different angles of exposition to the flux, and Sizaret et al (2009) proposed an inverse method to reconstruct the local paleoflow velocity and direction by analyzing growth bands.…”

Structural, mineralogical, and paleoflow velocity constraints on Hercynian tin mineralization: the Achmmach prospect of the Moroccan Central Massif

International audienceThe Achmmach tin mineralization (NE of theMoroccan Central Massif) is associated with tourmaline-richalteration halos, veins, and faults hosted in sandstones andmetapelites of the Upper Visean-Namurian. These depositsare reported to be late Hercynian in age and related to theemplacement of late-orogenic granite not outcropping in thestudied area. Structural and paragenetic studies of theAchmmach tin deposit were conducted in order to establisha general model of the mineralization. From field constraints,the late Hercynian phase is marked by a transition fromtranspression to extension with deformation conditions evolvingfrom ductile to brittle environments. The transpression(horizontal shortening direction roughly trending E-W) is coevalwith the emplacement of the first tourmaline halos alongseveral conjugated trends (N070, N020, and N120).Thereafter, a tourmaline-rich breccia formed in response tothe fracturing of early tourmaline-altered rocks.Subsequently, during the extensional phase, these structureswere reactivated as normal faults and breccias, allowing theformation of the main tin mineralization (cassiterite) associatedwith a wide variety of sulfides (arsenopyrite, chalcopyrite,sphalerite, galena, pyrrhotite, bismuthinite, pyrite, and stannite). This evolution ends with fluorite and carbonate deposition.The hydrothermal fluid flow velocity, calculated byapplying statistical measures on the tourmaline growth bands,varies with the lithology. Values are lower in metapelites andhigher in breccia. In the general evolution model proposedhere, tourmaline alteration makes the rock more competent,allowing for brittle fracturing and generation of open spacewhere the main Sn mineralization was precipitated

“…This problem is compounded by the spread of data points due to experimental inaccuracy and by phenomena such as growth rate dispersion and influence of additives. Values of constants appearing in the kinetic expressions can therefore rarely be determined with an accuracy of better than 730% [14]. Growth rate experiments themselves in the case of lactose crystallisation are not found to be enough to describe the mechanisms of growth observed.…”
