This includes the biological, chemical, mineralogical, mechanical, paleontological, physical, petrophysical, and stratigraphical aspects of such rocks and sediments evaluated from the microscopic level to the regional geographical level and with their application to the discovery and exploitation of natural resources. We will try to cover a little of each. Dolomite occurs in crystalline and noncrystalline forms, is clearly associated and often interbedded with limestone, and usually represents a postdepositional replacement of limestone. Limestones include chalk, calcarenite, coquina, and travertine, and they effervesce freely with any common acid. Usage of the term prior to 1960 may also be synonymous with what would later be known as dolomite, especially within the context of field descriptions.
Petrology is broader in scope than petrography.
