  2. Rock cycle - Wikipedia

    en.wikipedia.org/wiki/Rock_cycle

    For example, an igneous rock such as basalt may break down and dissolve when exposed to the atmosphere, or melt as it is subducted under a continent. Due to the driving forces of the rock cycle, plate tectonics and the water cycle, rocks do not remain in equilibrium and change as they encounter new environments. The rock cycle explains how the ...

  3. Original - The rock cycle is a fundamental concept in geology that describes the dynamic transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Due to the driving forces of the rock cycle, plate tectonics and the water cycle , rocks do not remain in equilibrium and are forced to change as they ...

  4. Historical geology - Wikipedia

    en.wikipedia.org/wiki/Historical_geology

    Weathering, erosion, and deposition are examples of gradual geological processes, taking place over large sections of the geologic time scale. In the rock cycle, rocks are continually broken down, transported, and deposited, cycling through three main rock types: sedimentary, metamorphic, and igneous.

  5. Stage (stratigraphy) - Wikipedia

    en.wikipedia.org/wiki/Stage_(stratigraphy)

    In chronostratigraphy, a stage is a succession of rock strata laid down in a single age on the geologic timescale, which usually represents millions of years of deposition.A given stage of rock and the corresponding age of time will by convention have the same name, and the same boundaries.

  6. Cementation (geology) - Wikipedia

    en.wikipedia.org/wiki/Cementation_(geology)

    Minerals bond grains of sediment together by growing around them. This process is called cementation and is a part of the rock cycle. Cementation involves ions carried in groundwater chemically precipitating to form new crystalline material between sedimentary grains. The new pore-filling minerals form "bridges" between original sediment grains ...

    An example of using thermal modeling in P-T-t path reconstruction. The above diagram shows the calculated geothermal gradients upon crustal thickening at 0 million year (m.y.) followed by an immediate uplift event at a rate of 1 mm per year. The P-T-t evolution of a rock originally at 40 km below ground is marked as red dots on the diagram.
