Carbonate Sedimentary Rock Classification

Oct 26, 2000· Two carbonate classification systems are in common use today, one by R.L. Folk and the second by R.J. Dunham . The Dunham system is based on depositional texture (that is, the amount of matrix surrounding the grains at the time of deposition). It uses such names as mudstone, wackestone, packstone, grainstone, and boundstone.

A Classification of Limestone Reservoirs1 | AAPG Bulletin ...

This paper contains a classification of limestone reservoirs based on the origin of the openings in the rock. It is shown that the most important type of reservoir is one in which porosity has been developed by erosion which took place before the time of deposition of the beds now overlying the reservoir.

Sedimentary Rock Classification

Oct 26, 2000· A good classification is based on some theory that explains how the rocks form, and are related to each other. We want to group together rocks that form by similar processes. The most general theoretical model we have for sedimentary rocks is the simple ideal model.The basic classification is based on that model.

What are the Different Gravel Sizes? (with pictures)

Aug 04, 2020· Size #10 gravel can be made from a variety of larger stones, but is most often made from slag or limestone. Size #57 gravel is often used to make walkways or for decoration. Size #67 is usually about the same size as #10, but often has a slightly different purpose. It's commonly used as fill in roadways and concrete slabbing.

Porosity - AAPG Wiki

Aug 29, 2016· Primary porosity in clastic and some carbonate rocks (such as oolites) is a function of grain size, packing, shape, sorting, and amount of intergranular matrix and cement. In theory, porosity is independent of grain size. Changes in grain size, however, affect grain shape and sorting.

Indiana Limestone | Indiana Geological & Water Survey

Indiana Limestone, which is a Mississippian-age grainstone of very uniform texture and grade, has gained world-wide acceptance as a premier dimension stone. The Salem Limestone, which is the geologic formational name for this carbonate unit, crops out in a belt that trends southward from Stinesville in Monroe County to Bedford in Lawrence County.

About Limestone & Sandstone - Salado | Texas Quarries

Limestone is one of the most popular and usable dimension stones available. Limestone has a uniform texture and grade that weathers naturally over time, gaining a natural patina and improving in appearance over time. While subtle color and grain variations are present within a deposit, limestone is actually very homogeneous for a natural product.
