Document Summary

Quaternary period: holocene -0. 01mya to now, pleistocene 2. 6mya to 0. 01mya. Carboniferous period: pennsylvanian 318mya-299mya, mississippian 359mya-318mya. Types of sedimentary environments fluvial: deposition in rivers +floodplains. Deltaic: deposition in sediment accumulations @ river mouths. Small crystals and natural glass particles, often altered to pale clay. Processes associated with the river that contribute to development of landslides in the river valley. Factors affecting the colour and clarity of the water. Reddish rock next to coal= clinker how do clinkers form and what is their relationship to coal. They are burnt coal formed by oxidation (why they are red in colour) Topographic maps: show natural and artificial features of the land surface. Geologic maps: typically shaded to show the rock-units that exist immediately below the surface. Cross sections: interpretations of what you would see if you could look at a slice cut through the outer parts of the earth. Geologic history: written account of the history of an area.
