Fluid Migration History from Analysis of Filling Fractures in a Carbonate Formation (Lower Cretaceous, Middle Magdalena Valley Basin, Colombia)

Petrographic and SEM data indicate that the veins are fracture filling structures, with three types of textures:1) Granular aggregates of calcite (GA); 2) Elongated granular aggregates of calcite (EGA); and 3) Fibrous aggregates of calcite and dolomite (FA). The textural relationship suggests that GA must have been formed in an environment of widespread extension of the basin, while EGA and FA must have been formed in a compressive environment. The geochemical analyses of REE carried out in the dominant fill of the veins (GA) indicate that these fillings must have been formed in a closed system (intraformational fluid movement) for the drilling well Alfa-1, while in the drilling wells Alfa-2 and Alfa 3, these fills (GA) must have been formed in a characteristic environment of open system (transformational fluid movement). -
Coulsonite Fev2o4—A Rare Vanadium Spinel Group Mineral in Metamorphosed Massive Sulfide Ores of the Kola Region, Russia
minerals Article Coulsonite FeV2O4—A Rare Vanadium Spinel Group Mineral in Metamorphosed Massive Sulfide Ores of the Kola Region, Russia Alena A. Kompanchenko Geological Institute of the Federal Research Centre “Kola Science Centre of the Russian Academy of Sciences”, 14 Fersman Street, 184209 Apatity, Russia; [email protected]; Tel.: +7-921-048-8782 Received: 24 August 2020; Accepted: 21 September 2020; Published: 24 September 2020 Abstract: This work presents new data on a rare vanadium spinel group mineral, i.e., coulsonite FeV2O4 established in massive sulfide ores of the Bragino occurrence in the Kola region, Russia. Coulsonite in massive sulfide ores of the Bragino occurrence is one of the most common vanadium minerals. Three varieties of coulsonite were established based on its chemical composition, some physical properties, and mineral association: coulsonite-I, coulsonite-II, and coulsonite-III. Coulsonite-I forms octahedral crystal clusters of up to 500 µm, and has a uniformly high content of 2 Cr2O3 (20–30 wt.%), ZnO (up to 4.5 wt.%), and MnO (2.8 wt.%), high microhardness (743 kg/mm ) and coefficient of reflection. Coulsonite-II was found in relics of quartz–albite veins in association with other vanadium minerals. Its features are a thin tabular shape and enrichment in TiO2 of up to 18 wt.%. Coulsonite-III is the most common variety in massive sulfide ores of the Bragino occurrence. Coulsonite-III forms octahedral crystals of up to 150 µm, crystal clusters, and intergrowths with V-bearing ilmenite, W-V-bearing rutile, Sc-V-bearing senaite, etc. Chemical composition of coulsonite-III is characterized by wide variation of the major compounds—Fe, V, Cr. -

Jenkins1 6 7 8 1 Department of Geological Sciences and Environmental Studies 9 Binghamton University 10 Binghamton, NY, 13902 11 2 Present address: Department of Earth and Environmental Sciences, Rutgers University, 12 Newark, NJ 07102 13 14 *Corresponding author 15 16 17 1 18 Abstract 19 Scapolites are widespread rock-forming aluminosilicates, appearing in metasomatic and igneous 20 environments, and metamorphic terrains. Marialite (Na4Al3Si9O24Cl) is the Cl-rich end member 21 of the group. Even though Cl-rich scapolite is presumably stable over a wide range of pressure 22 and temperature, little is known about its stability field. Understanding Cl-rich scapolite 23 paragenesis is important since it can help identifying subsurface fluid flow, metamorphic and 24 isotopic equilibration. Due to its metasomatic nature Cl-rich scapolite is commonly reported in 25 economic ore deposits, hence it is of critical interest to the mineral resource industries who seek 26 to better understand processes contributing to mineralization. In this experimental study two 27 reactions were investigated. The first one was the anhydrous reaction of albite + halite to form 28 marialite (3NaAlSi3O8 + NaCl = Na4Al3Si9O24Cl (1)). The second reaction was the 29 hydrothermal equivalent described by H2O + Na4Al3Si9O24Cl = 3NaAlSi3O8 + liquid (2), where 30 the liquid is assumed to be a saline-rich hydrous-silicate melt. Experiments were performed 31 using a piston-cylinder press and internally heated gas vessels. The temperature and pressure 32 conditions range from 700-1050°C and 0.5-2.0 GPa, respectively. -
