Some rare rocks, such as the monomineralic types that occur in layered igneous rock bodies (Wager & Brown ), are believed to have differentiated under special conditions. The study of layered igneous rock reveals that there are many differentiation factors that can modify the normal sequence of crystal- lization-differentiation within a Cited by: 4.

    Early Stage (– Ma). Earliest magmatism is recorded in several small ultramafic to mafic intrusions in the Lake Nipigon area of Ontario that are commonly mineralized with Ni-Cu-PGE sulfide (Heaman et al., ).The oldest dated volcanics in the Midcontinent Rift are Ma (Davis and Green, ).The lower sections of the early stage volcanics are generally primitive olivine.

However, it has come to be used by geologists to describe igneous rocks that contain macroscopic inhomogeneities with an essentially sheet-like form, although it should be noted that in many outcrops of limited size these inhomogeneities may appear to be two-dimensional.

In this chapter, we consider the classification of igneous rocks in more detail, and we see, for example, that some rock types commonly occur together, whereas others are never associated.

In Chapter 8, we learned about igneous rock-forming processes – why rocks melt, where they melt, and how they melt. He visited Greenland several times, and his many publications on this topic culminated in a monumental book, Layered Igneous Rocks, completed by G.M.

Igneous rocks formed by sedimentation are termed cumulates (Latin cumulus, a heap), and characteristically display cumulate general development of ideas on this subject is described by Wager and Brown ().However, Irvine () redefines cumulate so that crystal settling is a possible, but not essential, process in the origin of the rocks to which the term is applied.

The general pattern of the behaviour of gallium in the rocks and minerals of the intrusion was determined by the early work of Wager and Mitchell () who, using optical emission spectrography, established that gallium was largely concentrated in plagioclase and magnetite, and found rather little variation in the gallium content of the whole Cited by: 5.
