The document provides examples of these techniques and how paleocurrent analysis has been applied to study areas in western Maine.
Metamorphic facies
The document describes the different metamorphic facies defined by their mineral assemblages under varying pressure and temperature conditions within the Earth's crust and upper mantle. It outlines the key facies including zeolite, prehnite-pumpellyite, greenschist, amphibolite, granulite, blueschist, eclogite, albite-epidote hornfels, hornblende hornfels, pyroxene hornfels, and sanidinite facies. Each facies is characterized by index minerals and typical mineral assemblages that reflect the prevailing metamorphic conditions.
Stereographic projection
Stereographic projection is a powerful method for representing planar and linear geological features by plotting their orientations on a stereonet. It allows geologists to visualize and analyze structural data. A stereonet is a lower hemisphere projection where great circles represent planar features like bedding planes, and points represent linear features like fold axes. Various geological data can be plotted on a stereonet, including strike and dip of planes, plunge and trend of linear features, and poles to planes. This allows interpreting relationships between structures and reconstructing geometries, like determining the orientation of an ore body in relation to a dike intruding folded beds. Stereographic projection is an invaluable tool in structural geology.
Carbonatites
The document summarizes a seminar on carbonatites. Carbonatites are igneous rocks composed of more than 50% carbonate minerals such as calcite or dolomite. They can be intrusive or extrusive. Carbonatites form from low degrees of partial melting in the mantle and have unusual geochemistry dominated by incompatible elements. They are often associated with alkaline complexes and may contain economic concentrations of rare earth elements, niobium, and fluorite. The document outlines the mineralogy, texture, classification, geochemistry, theories of origin, world occurrences, and economic importance of carbonatites.
Fluids inclusion of metamorphic rocks
Fluid inclusions in metamorphic rocks provide information about fluids present during metamorphism. Fluid inclusions form when small portions of fluid get trapped in mineral crystals during their growth. Studies of fluid inclusions in South Indian granulites show they commonly contain CO2-rich fluids. Massive/banded charnockites from this region experienced high-grade metamorphism between 5-10.5 kbars and 550-880°C, indicating burial depths of 12-35 km. The quartz in these rocks contains primary and pseudosecondary CO2-rich inclusions with densities of 1.10-1.15 g/cc, providing evidence of the presence of CO2-rich fluids
Garnet GROUP OF MINERAL
Garnet is a group of six silicate minerals that are isomorphous and never occur in pure form. They vary slightly in properties but can be indistinguishable without analysis. Garnets have the general formula X3Y2(SiO4)3 and consist of silicon tetrahedrons linked to distorted metal octahedrons, forming a cubic crystal structure. They commonly occur as dodecahedrons or trapezohedrons and vary in color from red to green to black. Garnets are used as abrasives, for water jet cutting, filtration, and as gemstones due to their variety of colors and hardness.

It can be found in color pink, white, gray, or brown. Feldspar is the name given to a group of minerals distinguished by the presence of alumina and silica (SiO2) in their chemistry. Feldspars (KAlSi3O8 – NaAISi3O8 – CaAl2Si2O8) are a group of rock- forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight. Feldspar is the most famous mineral that can be seen in the earth’s crust – and in our daily lives, Like dinnerware, bathroom and building tiles. Feldspar is used by various industries like Palash internationals in different applications. Palash Internationals is the most abundant Feldspar Manufacturers in India.
