Richard Arculus
Richard John Arculus is an Australian petrology, petrologist and volcanologist, formerly a professor of the School of Earth Sciences at the Australian National University. His research interests and areas of expertise include inorganic geochemistry, igneous petrology, metamorphic petrology, volcanology, and chemical oceanography. Arculus graduated with a British undergraduate degree classification#First-class honours, first-class degree in Geology from Durham University in 1970. He then earned a PhD from the same institution in 1973. Following his time at Durham he was a post-doctoral fellow of the Carnegie Institution for Science. Career Through the 70s, 80s, and early 90s he held academic positions in the United States at Rice University and the University of Michigan, before moving to Australia to work at the University of New England (Australia), University of New England. Arculus joined ANU as a full professor in 1994. He successfully campaigned for Australia to join the Inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petrology
Petrology () is the branch of geology that studies rocks and the conditions under which they form. Petrology has three subdivisions: igneous, metamorphic, and sedimentary petrology. Igneous and metamorphic petrology are commonly taught together because they both contain heavy use of chemistry, chemical methods, and phase diagrams. Sedimentary petrology is, on the other hand, commonly taught together with stratigraphy because it deals with the processes that form sedimentary rock. Background Lithology was once approximately synonymous with petrography, but in current usage, lithology focuses on macroscopic hand-sample or outcrop-scale description of rocks while petrography is the speciality that deals with microscopic details. In the petroleum industry, lithology, or more specifically mud logging, is the graphic representation of geological formations being drilled through and drawn on a log called a mud log. As the cuttings are circulated out of the borehole, they are sam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
