The document provides an overview of a course on carbonates and sedimentary basins. It discusses how carbonate sediments form in different depositional environments and the factors controlling carbonate accumulation and distribution. It also summarizes the key components and textures of carbonate rocks and the processes of diagenesis.

4. Sedimentary rocks are the product of the creation, transport, deposition, and diagenesis of detritus and solutes derived from pre-existing rocks.

113. Global Climate Cycles Global climatic cycles, referenced to geologic periods (yellow), megasequences (light purple), sea level cycles (blue), & volcanic output (dark purple). (Redrawn & modified L. Waite, 2002 after Fischer, 1984)

114. Frakes et al. (1992) have alternating cold & warm states ("cool" & "warm" modes) at comparable time scales to Fischer (1984) cycles but propose older portion of Mesozoic greenhouse (Middle Jurassic to Early Cretaceous) has a cool climate, & presence of seasonal ice at higher latitudes (after L. Waite, 2002) Phanerozoic Global Climate History
