Question

Difference between calcarious and carbonacious rocks....

Answer 1

Calcareous rocks are formed due to the gradual deposition and accumulation of sediments derived from the decaying matter of animals and plants containing lime. eg. Limestone

Carbonaceous rocks are actually vegetation remnants that are buried and undergo changes due to pressure from overlying deposits and earth movements. eg. Lignite

Answer 2

Sedimentary rocks comprising an important improvement in the primary matter over medium deposits are charged carbonaceous sedimentary rocks. The volume of organic matter compelled to characterize debris as carbonaceous is not substantially stabilized.

Calcareous stones are carbonated ingredients, generally dolostone. Typically develop in continuous continental rock elements completing an enduring boundary. They may be uncomplicated carbonate, or they may collect shifting products of other precipitates in the form of hematite.
