Document Summary
Geo-archaeology: application of the techniques of the earth sciences. Earth sciences: sciences related to earths physical spheres. Sciences of the lithosphere, hydrosphere, atmosphere, cryosphere, biosphere: petrology: study of rocks & minerals (study of the lithosphere) Exhibit distinct physical properties crystal shape, colour, hardness. Types or rocks/minerals can only occur where ingredients are present. Sedimentary rocks/minerals generated by depositional event (grand canyon) Metamporphic minerals/rocks modified temperature or pressure of deep burial. Minerals identified by; shape, colour, cleavage, fluorescence & pleochroism. William stratus smith: by identification of exposed outcrops: articulation with archaeology: Unique structure/composition illustrates raw material source (origin of material) Covers and preserves them. (spatial relationships: sedimentology: the study of the regolith. Extremely small silt (dust from the movement glaciers) and colloid (chemical reaction) particles. Generation how did that sediment come to be. Transformational history life history of the sediment since deposition. Cultural modification what transformations were a product of human activity. In residual sediments (those deposited adjacent to their source)
