Laboratory Handbook of Petrographic Techniques

The standard methods of rock and mineral thin section preparation are so widely used that they need no decription here. Adequate accounts may be found in Johannsen (1981), but the most thorough and up to date treatment of the subject appears in Hartshorne and Stuart. Only a few new techniqies which are considered to improve thin-section quality and especially to make the sections generally appl…

Andesites : Orogenic Andesites and Related Rocks

The Earth's crust has formed from the mantle as a result pof magmatic activity over 3700 Ma. At present such acticity occurs dominantly at lithospheric plate boundaries, althought minor magmatic activity also occurs within plates. Thus, volcanism can be classified according to its plate tectonic setting as summarized in Tabel. 1 Volcanism at constructive margins (Oceanic Ridges) is dominantly s…

Rock - Color Chart

The color names have been taken from ISCC-NBS system as described in U.S.National Bureau of Standards Special Publication SP440 as this system has been accepted by a larger number of scientific organizations. According to this system each color name, such as pale purple, occupies a field or portion of space in the color solid, whereas a Munsell designatuin, such as 5 P6/2 is represented by a po…

Magmas and Magmatic Rocks

In the past, rocks were usually regarded as aggregates of consolidated, naturally formed, in-animate matter from the Earth. Over the years this definition has been expanded to include unconsolidated materials, and natural, inanimate materials of extraterrestrial origin. A rock is now generally regarded as being a naturally formed body of solid, inanimate matter that has some degree of internal …

An introduction to the rock forming minerals

The minerals of the olivine group all possess orthorhombie symmety and a structure consisting of independent tetrahedra linked by divalent atoms in octahedral coordination. Minerals of the group show complete diadochy between the atomic pairs Mg and Fe+2 and Mn, i.e. between forsterite, Mn2Si04, and fayalite, Fe2Sio4, and between fayalite and tephroite, Mn2Sio4. The other members of the group a…

Petrographic Mineralogy

The student of petrography, if possible, shoulf make an attempt to get the complet story of each sample. Under indeal conditions he would start with the examination and systematic sampling of rock masses in the field. Frequently a study of field exposure yields information that is invaluable in the laboratory study of hand specimens and thin sections. Samples are collected in the filed under a …

Introduction to Theoretical Igneous Petrology

Petrology is the science concerned with the composition, origin, and natural history of rocks. Igneous petrology is a narrower field in which consideration is given to facts an theories resulting from study of rocks that were once partly or completely molten. Volcanology is a special field of igneous petrology in ehick emphasis is placed on phenomena associated with extrusive igneous rocks, esp…
