GLY 4200 Lecture 1 Fall 2017 2 Classical Definition of Mineral From Edward Salisbury Dana A body produced by the processes of inorganic nature having usually a definite chemical composition and if formed under favorable conditions a certain characteristic atomic structure which is expressed in its crystalline form and other properties.

Portable X-Ray Fluorescence (XRF) instruments allow a large amount of data to be obtained rapidly, with minimal sample preparation or drilling impact, and at low cost. Rock powders, cuttings, slabs or core faces can be analysed directly using this non-destructive technique. XRF analyses provide highly precise, and if calibrated properly, accurate data on the bulk chemistry. Proprietary normative mineral algorithms are applied in order to convert the elemental chemical data to mineralogy. Mineral abundances determined from the XRF analyses correlate well with those obtained by X-Ray Diffraction, thin section point counting and SEM analyses. The vast majority of the data fall within the 5% envelope expected from the precision of the XRD analyses when compared with XRF determined mineralogy. Mineralogy in the Montney is variable and the most abundant minerals are calcite, dolomite, quartz, feldspar and . Lab 11 – Fall, . 2016. Feldspars: . Exsolution. , Zoning, and Twinning. 2. Feldspars. Feldspar minerals are the most common minerals in the earth's crust. They are aluminosilicates of potassium, calcium, and sodium. HIGHER-GRADE REGIONAL METAMORPHICS.

In order to observe an interference figure the microscope must be used in the . conoscopic. mode. Conoscopic. refers to the cone-shaped illumination obtained when the condenser lens is near the thin section. . A mineral is naturally occurring homogeneous inorganic substance having distinctive physical properties and a more or less definite chemical composition.. Minerals are to a large extent the units which make up the rocks of the earths crust or the outer shell..
