Mottled rock
NettetThe mottled rock enclosing the fossils consists of broken up bits of fossils, lime mud, and fecal pellets from the wide range of skeletal and soft-bodied invertebrates. The wide range of fossil organisms, combined with paleomagnetic information, indicate that this area of Manitoba was a relatively warm, inland sea that just south of the Ordovician paleoequator. NettetPetrographic and chemical studies combined with field observations indicate probable origins of these types. A review of other reports of mottled carbonate rocks indicates the existence of several additional types of mottling. Each type is the result of variations of the processes which cause the segregation of the component minerals.

Anorthosite is a phaneritic, intrusive igneous rock characterized by its composition: mostly plagioclase feldspar (90–100%), with a minimal mafic component (0–10%). Pyroxene, ilmenite, magnetite, and olivine are the mafic minerals most commonly present. Anorthosites are of enormous geologic interest, because it is still not fully understood how they form. Most models involve separating plagioclase crystals based on their density. Plagioclase cry…
