Sedimentary Rocks | Geology
Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks. As discussed in the "Earth's Minerals" chapter, dissolved ions in fluids precipitate out of the fluid and settle out, just like the halite in Figure 5.

sedimentary rock
Sedimentary rock can also be formed when the shells of sea creatures fall to the floor of the sea after the creatures die. When the shells form a thick enough layer they become compressed and form rock. In some places where there are shallow bodies of water another kind of sedimentary rock may be formed. In these cases, if the surrounding air ...
Chapter 11 SEDIMENTARY BASINS
SEDIMENTARY BASINS 1. INTRODUCTION 1.1 The official definition of a sedimentary basin is: a low area in the Earth's crust, of tectonic origin, in which sediments accumulate. Sedimentary basins range in size from as small as hundreds of meters to large parts of ocean basins. The essential element of the concept is tectonic creation of relief, to
