Chalk formation

Chalk is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite.Calcite is an ionic salt called calcium carbonate or CaCO 3.It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite shells (coccoliths) shed from micro-organisms called coccolithophores. Flint (a type of chert) is very common as bands parallel ....

The Log Format. At the top of the log is the header which records: The banner of the logging company. the name of the energy company. the types of log recorded on run. the name and location of the well. the date of the logging operation. the ground elevation (GL) and Kelly bushing elevation (KB) the drill-bit size.Distribution--The belt of outcrop of the chalk beds in Kansas extends from Jewell, Smith, and Phillips Counties to Kearny and Hamilton Counties; the formation is restricted to approximately the northwestern one-fifth of the state. The eastern edge of the outcrop has been indented by incision of streams, so that it forms a very irregular pattern.
