Petrology

Earth-Science Reviews, 1991
Publisher Summary This chapter discusses the petrology of Victorian brown coals in terms of their visible constituent elements. The Victorian brown coals occur in beds or seams ranging in thickness from a few centimeters to over 100 m extending laterally from a few meters to over 50 km. These bands are formed of coals belonging to different lithotypes

Archean granitoids: classification, petrology, geochemistry and origin

Special Publications, 2019
This paper describes the petrology, geochemistry and petrogenesis of Archean granitoids. Archean granites define a continuum of compositions between several end members: (i) magmas that originated by partial melting of a range of crustal sources, from ...

What is a Kimberlite? Petrology and Mineralogy of Hypabyssal Kimberlites

, 2019
Hypabyssal kimberlites are subvolcanic intrusive rocks crystallised from mantle-derived magmas poor in SiO2 and rich in CO2 and H2O. They are complex, hybrid rocks containing significant amounts of mantle-derived fragments, primarily olivine with rare ...

Petrology and Geochronology of Rutile

, 2017
Rutile (TiO2) is an important accessory mineral that, when present, offers a rich source of information about the rock units in which it is incorporated. It occurs in a variety of specific microstructural settings, contains significant amounts of several

Porosity of Devonian and Mississippian New Albany Shale across a maturation gradient: Insights from organic petrology, gas adsorption, and mercury intrusion

, 2013
The evolution of porosity in shales with increasing maturity was examined in a suite of five New Albany Shale samples spanning a maturity range from immature (vitrinite reflectance, Ro 0.35%) to postmature (Ro 1.41%).

The metamorphosis of metamorphic petrology

, 2016
The past half-century has seen an explosion in the breadth and depth of studies of metamorphic terranes and of the processes that shaped them. These developments have come from a number of different disciplines and have culminated in an unprecedented ...

Petrology of moldavites

Geochimica et Cosmochimica Acta, 1969
Abstract During the systematic petrological examination of 311 Bohemian and 130 Moravian moldavites, layered Muong Nong type specimens were found to be fairly common. In these layered forms mineral grains which appear to be detrital were found in one specimen, another contains thin bubbles of irregular angular outline, and other specimens contain ...
