Uncategorized Geophysical Prospecting : Gravity 15 Sep 2013 Two major emphases of geophysics: "pure" "applied" 1. pure geophysics - study of the physics of the Earth Examples: variations in temperature with depth causes of reversals in Earth's magnetic field 2. applied geophysics (also called exploration…
Petrology Metamorphic Textures 15 Sep 201315 Sep 2013 Metamorphic rocks exhibit a variety of textures. These can range from textures similar to the original protolith at low grades of metamorphism, to textures that are purely produced during metamorphism…

Petrology Metamorphic Petrology: Introduction 13 Sep 201313 Sep 2013 Metamorphism is defined as follows: The mineralogical and structural adjustment of solid rocks to physical and chemical conditions that have been imposed at depths below the near surface zones of…
Mineralogy Crystal Morphology and Crystal Symmetry 13 Sep 201313 Sep 2013 The symmetry observed in crystals as exhibited by their crystal faces is due to the ordered internal arrangement of atoms in a crystal structure, as mentioned previously. This arrangement of…

Mineralogy Symmetry Elements – The 32 Crystal Classes 12 Sep 201312 Sep 2013 As stated in the last post, there are 32 possible combinations of symmetry operations that define the external symmetry of crystals. These 32 possible combinations result in the 32 crystal…
Geophysical Prospecting Geophysical Exploration of Gold 11 Sep 2013 It is almost impossible to use Geophysical Prospecting methods for exploration of gold as it is present in very low grades in the subsurface. However indirect geophysical indications may occur…
Mineralogy Crystallography 11 Sep 201311 Sep 2013 DEFINITION OF A MINERAL A mineral is a naturally occurring homogeneous solid with a definite (but not generally fixed) chemical composition and a highly ordered atomic arrangement, usually formed by an inorganic process. Naturally Occurring - Means it…
