The loss of heat through radiation and gradual cooling led to solidification and hardening of the upper portion. Lecture notes . Magma is a hot viscous, siliceous melt, containing water vapour and gases. Igneous Rocks: A change of temperature caused the formation of igneous rocks. pyroclastic . 2 • Why is the Earth hot inside? Lecture 1 . 1. Part 2. The IUGS mineralogical based classification and nomenclature scheme for phaneritic and aphanitic igneous rocks. Some pictures from the trip!!!!. Find University Of Eldoret Ees 301:Igneous Petrology previous year question paper. IGNEOUS PETROLOGY General Procedures . Feel free to use the past paper as you prepare for your upcoming examinations. Abstract. McDermott) The basic terminology of igneous petrology. Note that the lithosphere is comprised of both crust and part of the upper mantle. Procedures used during Leg 176 for describing igneous rocks in general follow the outline presented in the "Explanatory Notes" chapter of Leg 153 (Shipboard Scientific Party, 1995), and much of the discussion presented here comes from that source.
