Ore Deposit - an overview | ScienceDirect Topics
Ore deposits that are associated with mafic to ultramafic igneous rocks can generally be divided into those where the metals of interest are hosted in oxide minerals and those where the metals of interest are held as sulfides or are strongly associated with sulfides (e.g., PGE alloys, arsenides, bismuthinides). The oxide ore bodies include stratiform, podiform, and breccia-related chromite ...

Genetic Model of Ore Deposits ~ Mining Geology
18-05-2015 · SEDEX ore deposits are formed due to concurrent release of ore-bearing hydrothermal fluids into aqueous reservoir mainly ocean, resulting in the precipitation of stratiform zinc-lead sulfide ore in a marine basin environment. The stratification may be obscured due to post depositional deformation and remobilization.

Marble Rock: Geology, Properties, Uses - ThoughtCo
02-12-2019 · Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. In its pure form, marble is a white stone with a crystalline and sugary appearance, consisting of calcium carbonate (CaCO 3).Usually, marble contains other minerals, including quartz, graphite, pyrite, and iron oxides.These minerals can give marble a pink, brown, gray, green, or variegated coloration.
USGS-Publications B1693 -- Mineral Deposit Models
This publication describes the geologic characteristics of a number of specific mineral deposits and their regional geologic environments. The compendium of geologic models presented includes 85 descriptive models giving identifying attributes of the deposit type and 60 grade-tonnage models giving estimated pre-mining tonnages and grades from over 3900 well-characterized deposits.

Narrow-vein modelling and Mineral Resource …
Most vein modelling and Mineral Resource estimation methods for narrow vein deposits uses three dimensional (3D) block grade estimation, based on kriging and inverse distance weighting. In addition, most modelling packages require the assumption of a constant dip and dip direction for the whole vein.
